   What's New

              The B2000 badge offers numerous extensions to B1000A features and provides
              a platform to support future wireless growth and standards. The following list
              summarizes the features available in the B2000 badge:
              • End-User Features on page 13
              • Configuration Support on page 14
              • Hardware and Infrastructure Features on page 15

              Important: The B2000 features described in this document require Vocera 4.0
              Service Pack 5 or greater.


End-User Features
              This section briefly describes the new features of the B2000 that improve or
              change the badge-user's experience.
              • Improved display screen
                The B2000 badge features a high-contrast, high-resolution display with an
                extensive grey-scale to provide greater readability. This display allows for fonts
                that use both upper- and lower-case characters. The B1000A LCD does not
                have grey-scale capabilities, and all characters are represented in upper case.
                See Display Screen on page 21.
              • Selectable font for messages
                If you use the badge to receive text messages, you can choose the font that
                provides the best readability for you. See Adjusting the Message Font on
                page 26.
              • Screen saver
                The B2000 badge provides a screen saver that displays your first name with
                the initial of your last name and also an icon indicating the remaining battery

  Configuration Support


                          Most exterior surfaces of the B2000 badge incorporate an antimicrobial
                          additive from BioCote® to inhibit the growth of bacteria, mold, and fungi.
                          See Anti-Microbial Protection on page 27.
                     • Simultaneous call announcements
                          When the Announce Through Speaker property is enabled, the B2000
                          provides call announcements through both the badge speaker and the
                          headset. These dual announcements ensure that you will always be notified
                          of an incoming call, even if your headset is temporarily off. After accepting
                          the call, the audio is only through the headset.
                          When this property is enabled in the B1000A badge, the call announcement
                          is played through the speaker only.
                          See Using the Announce through Speaker Commands in the Vocera User
                          Guide.
                     • Improved selection buttons
                          The selection buttons on the side of the B2000 badge are rubber-capped,
                          making them softer and easier to press.
                     • Searching for server notification
                          The B2000 provides a spoken reminder ("Searching for Server") if you press
                          the call button when the badge is not connected to the Vocera Server. See
                          Alert Tones and Notifications on page 27.
                     • Colored protective sleeves
                          The badge protective sleeve is now available in a variety of colors. As before,
                          the sleeve protects the badge from everyday wear and tear and helps to
                          extend its life. You can change batteries, operate buttons, and view the
                          display screen without removing the sleeve. See Protective Sleeves on
                          page 28.
                     • Backward-compatibility with existing batteries, chargers, and attachments
                          All existing devices work with the B2000 badge.


Configuration Support
                     The B2000 badge provides new capabilities that you can access through the
                     configuration utilities in Vocera. This section briefly describes the impact of the
                     B2000 on badge configuration.

                                                          Hardware and Infrastructure Features


                A badge profile is the set of properties that specifies how a badge connects
                to your network. B2000 and B1000A badges have independent profiles,
                allowing them to run on VLANs that have different network and security
                settings. See About Badge Profiles on page 45.
              • Badge Properties Editor interface
                The Badge Properties Editor provides an interface for creating both
                B2000 and B1000A profiles. See Using the Badge Properties Editor on
                page 47.
              • Badge Configuration Utility extensions
                The Badge Configuration Utility has been extended to allow you to
                configure B2000 and B1000A badges simultaneously. See Using the Badge
                Properties Editor on page 47.
              • Badge configuration menus
                You access the internal badge configuration menus in slightly different ways
                for the B2000 and the B1000A. See Displaying the Badge Configuration
                Menu on page 70.
              • Property names
                Because B2000 and B1000A badges have independent profiles, their
                properties have different names. See Badge Property Reference on
                page 83.


Hardware and Infrastructure Features
              The B2000 badge provides a new radio and antenna that offer significant
              enhancements to the capabilities of the B1000A hardware. This section briefly
              describes the features enabled by the new hardware and their impact on your
              network environment.
              • 802.11g support
                The B2000 radio can run in either 802.11b or .11g mode. Sites can take
                full advantage of an 802.11g network by deploying B2000 badges. See
                802.11b/g Support on page 97.
              • WPA2 support
                The B2000 supports the following elements of the WPA2 standard:
                • EAP Types: EAP-FAST, WPA-PEAP and WPA-PSK.
                • Encryption: AES-CCMP.
                • Message Integrity: Michael 8 MIC.

                                                                               What's New ··· 15
  Hardware and Infrastructure Features


                        See WPA2 Support on page 108.
                     • WMM (WiFi Multimedia subset of 802.11e)
                        WMM provides standards-based QoS to prioritize voice over data traffic and
                        ensure high level voice quality. The B2000 badge allows you to use WMM to
                        prioritize packets. In order to take advantage of this standard, your access
                        points must also support it.
                     • APSD (Automatic Power Save Delivery subset of 802.11e)
                        APSD improves power management and potentially increases the talk time of
                        802.11 clients. The B2000 badge supports APSD. In order to take advantage
                        of this standard, your access points must also support it.
                     • Partial support for region-based channel selection (802.11d)
                        The B2000 badge provides automatic channel selection based on the country
                        code broadcast by access points. In order to take advantage of this standard,
                        your access points must also support it.
                     • Upgradeable platform
                        The software in the badge is built on a Linux-based operating system. The
                        new hardware provides an enhanced CPU and additional memory. Together,
                        the B2000 hardware and software provide a platform that helps to make the
                        badge architecture scalable for future needs.
                     • RoHS compliance
                        The B2000 badge is designed to the European RoHS directive, which provides
                        for environmentally friendly disposal of electrical products.
                     Full support for WMM, APSD, and region-based channel selection will be
                     provided in the first half of 2008 in a firmware service pack release.

                 • Protective Sleeves on page 28.


Display Screen
                 The display screen on the back of the badge provides status information and
                 a menu allowing you to view badge information and customize settings. The
                 display screen also allows you to view text messages sent by email, the Vocera
                 User Console, or an application that integrates with the Vocera system, such
                 as a nurse call system. See The Badge Menus on page 22 for information
                 about each of the screens in the badge menu.
                 The B2000 badge features a high-contrast, high-resolution display with an
                 extensive grey-scale to provide greater readability. This display allows for fonts
                 that use both upper- and lower-case characters.

                                                                        B2000 End-User Features ··· 21
  The Badge Menus


                     The B2000 badge automatically launches a screen saver when its display
                     is inactive. The screen saver shows your first name and the first initial of
                     your last name, along with an icon indicating the remaining battery life. The
                     badge dismisses this screen saver immediately if the display needs to become
                     active—for example, if you receive a call or a message.
                     You can manually interrupt the screen saver and return the badge to its
                     previous display by using any of the badge buttons:
                     • Pressing a side button dismisses the screen saver without taking any
                       additional action.
                     • Pressing the Call button dismisses the screen saver and also initiates a call.
                     • Pressing the DND/Hold button dismisses the screen saver and either places
                       the badge in DND mode or puts a call on hold.


The Badge Menus
                     The display on the back of the badge shows a series of menu screens that
                     comprise the top level of the menu system. To navigate through the menu
                     system, you use the Up, Select, and Down buttons on the side of the badge:

                     Figure 2. Badge selection buttons




                     Use the Select button to choose a displayed item. To return to the main screen
                     at any time, press and hold the Select button until the badge beeps.
                     If you press the Up button to scroll through the top-level menu, you see the
                     following choices: Messages, Font, Volume, Power Off, and Info (the Font menu
                     is not available on the B1000A badge). If you press the Up button once more,
                     the display returns to the main screen. Press the Down button to navigate in the
                     reverse direction.

                                            a call, this shows the name of the person with whom
                                            you are currently speaking. If you are already on a call
                                            and you hear the Call Waiting tone, this displays the
                                            name of the person who is trying to call you.
                                            If you are in a conference, this shows its name. If you
                                            are receiving a broadcast, this shows the name of the
                                            person making the broadcast.
                                            If you received a message, this shows the name of the
                                            person who sent the message for 15 seconds.

            Most of this information is intended to be used by your system administrator for
            diagnostic purposes.
            The Info menu provides the following information:
            • Battery. The battery strength is given in volts (V). The badge operates correctly
              when the battery level is 3.5 V or greater.
            • Badge MAC. The MAC address is a unique identifier for your badge that the
              Vocera server uses as the Badge ID.
            • Location. The name of the location or the physical network address of the
              access point with which your badge is currently communicating.
            • Badge IP. The Internet Protocol (IP) network address of the badge.

                     • Version. The version of the Vocera Server you are connected to and the
                       firmware that your badge is using.
                     • Server IP. The IP network address of the Vocera Server or the active node of
                       the Vocera Server cluster.
                     • Cluster. The IP network addresses of the nodes in the Vocera Server cluster, if
                       one exists.
                     • AP MAC. The physical ID of the access point to which the badge is currently
                       connected.
                     • User. The name of the person who is currently logged in to your network
                       with this badge.
                     • Radio. If the badge is connected to the network, displays the message
                       "Connected" and the channel that the radio is using; otherwise, displays the
                       message "Powering off."
                        In the B2000 badge, this screen also displays the signal-to-noise ration (SNR)
                        of the connection and plays a beep for the built-in survey tool that is used to
                        configure badges.
                        In the B1000A badge, this screen displays the proprietary CQ value that is
                        used to configure badges.
                     • SSID. The SSID of the access point the badge is connected to.


Adjusting the Message Font
                     You can adjust the way that the badge displays text messages. If you receive
                     a lot of text messages—for example, if your site integrates with a messaging
                     system such as a Nurse Call System—you may want to choose the display that is
                     most readable for you.

                     To adjust the font used by badge messages:
                       1. Turn the badge over, so you can see the display.
                       2. Press the Up button until you see the Font icon.

                   main screen.


Anti-Microbial Protection
               Most exterior surfaces of the B2000 badge incorporate an antimicrobial additive
               from BioCote® to inhibit the growth of bacteria, mold, and fungi. This additive
               is molded into the badge material, and you cannot wear it off or remove it by
               scratching the badge.
               A topical solution, also from BioCote, is applied to the buttons and the plastic
               display screen of the B2000 badge. The battery compartment, the inner surface
               of the battery, and the microphone screen do not incorporate antimicrobial
               protection.
               The BioCote additive is also molded into the material for all colors of the
               protective sleeve except black. See Protective Sleeves on page 28.


Alert Tones and Notifications
               Alert tones are controlled by settings on the Vocera server. Your badge may play
               any or all of the following alert tones:

                        DND Reminder                Plays a tone every 15 minutes to remind you that the
                                                    badge is in DND mode.

                       If you are not receiving a alert tone or reminder that you would find useful, or if
                       you do not want to be notified of any of the above conditions, ask your system
                       administrator to change the settings for your badge. The system administrator
                       can also set an option to disable all alerts when your badge is in Do Not Disturb
                       mode.
                       In addition to the alert tones, the B2000 provides a spoken notification
                       ("Searching for Server") if you press the call button when the badge is
                       connected to the network, but not connected to the Vocera Server.


Protective Sleeves
                       The protective sleeve safeguards the badge from everyday wear and tear and
                       helps to extend its life. You can change batteries, operate buttons, and view the
                       display screen without removing the sleeve. You must remove the sleeve before
                       placing the badge in the charger.

   Configuring New Badges

              To an end user, a badge is a convenient communication device. To your wireless
              network, however, a badge is a network client—it requires minor configuration
              before it can communicate with your network, as any IP device does.
              For example, you must either assign a badge a fixed IP address or specify that
              a DHCP server will assign an IP address dynamically. This IP address is a badge
              property. Similarly, you must specify other properties for your badge, such as
              the SSID your wireless network uses, and any security settings your network
              may require.
              This chapter summarizes the procedures for configuring an initial test badge,
              troubleshooting it if necessary, and then configuring the remaining badges.
              These procedures point to other chapters in the part called Configuring
              Badges on page 31, where the summarized tasks are described in detail.
              The first time you configure badges, you will need to refer to these other
              chapters for complete information. After you have configured badges once
              or twice, you can use this chapter by itself as a reminder of the basic steps in
              badge configuration.


Configuring a Test Badge
              When you perform the initial badge configuration, set up a single test
              badge first, confirm that it connects to the network the way you intended,
              and troubleshoot your badge.properties file if it does not. After you can
              successfully connect with this test badge, you can configure the remaining
              badges.

              Important: Make sure a single test badge can connect to your network before
              you configure all your badges. If you download incorrect properties to your
              badges and they cannot connect, you may need to reset the factory defaults on
              each individual badge—a labor-intensive process.




                                                                    Configuring New Badges ··· 33
  Configuring a Test Badge


                     To configure a test badge:
                       1. Set up a configuration computer using the network settings required to
                          connect to badges that have factory default settings.
                         See Setting Up the Configuration Computer on page 39 for details.
                       2. Use the Badge Properties Editor on the configuration computer to create
                          a badge.properties file that specifies how your badges connect to your
                          network.
                         See Creating a Property File to Download on page 45.

                         Best Practice: Use the Badge Properties Editor to specify that a DHCP
                         server is assigning IP addresses to the badges dynamically. If your badges
                         require static IP addresses, see Configuring Badges with Static IP
                         Addresses on page 36. This section assumes you are using a DHCP
                         server to assign IP addresses to the badges.

                       3. Make sure the production Vocera Server is running and the badge is within
                          range of the wireless network it is trying to connect to.
                         The badge will attempt to connect to the Vocera Server after updating itself
                         from the Badge Configuration Utility.
                       4. From the Windows Start menu on the configuration computer, choose
                          Programs > Vocera > Badge Utilities > Badge Configuration Utility.
                         The Badge Configuration Utility opens in a command window, displaying a
                         list of firmware components and properties that the utility will download.
                       5. Attach a charged battery to a new badge (a badge that has never been
                          configured).
                         A new badge automatically looks for the configuration computer (because
                         the IP address of the configuration computer is set to 10.0.0.1) and
                         connects to it. The Badge Configuration Utility displays the start session
                         message, then it automatically starts downloading firmware and properties
                         to the badge.
                         The Badge Configuration Utility continues to display messages as it
                         downloads the firmware and properties. When the download is complete,
                         it displays the message end session and appends the MAC address of the
                         badge to the macaddr.txt file in the \vocera\config directory.
                         Next, the badge reboots and tries to connect to the network using the SSID
                         and other network properties that you specified in the badge.properties
                         file.

                 If the badge successfully connects to the network, it then tries to connect
                 to the production Vocera server using the Vocera Server IP Address that you
                 specified in the badge.properties file.
               6. Look at the screen of the badge:
                 • The message “Logged Out” indicates that the badge is configured
                   properly and has connected to the Vocera server.
                    Continue with Configuring the Remaining Badges on page 35.
                 • If the badge does not display “Logged Out” within 30 seconds to one
                   minute, the badge is not configured properly and did not connect to the
                   Vocera server.
                    Continue with Troubleshooting Badge Configuration on page 67.
               7. Shut down the Badge Configuration Utility.
                 On the configuration computer, click the close icon in the upper-right
                 corner of the command window in which the Badge Configuration Utility is
                 running.
                 The Badge Configuration Utility session ends, and the command window
                 closes.
               8. After you are finished troubleshooting, copy the badge.properties file you
                  created on the configuration computer to the \vocera\config directory of
                  your production Vocera Server.
               9. Do either of the following:
                 • If your production Vocera Server is running, stop it and then restart it to
                   load the badge.properties file into memory.
                 • If your production Vocera Server is not running, start it to load the
                   badge.properties file into memory.
                 See Using the Vocera Control Panel in the Vocera Configuration Guide.


Configuring the Remaining Badges
              After you have successfully configured and tested one badge, configure the
              remaining badges for your site. The procedure for configuring these badges is
              essentially the same as the procedure described in Configuring a Test Badge
              on page 33; you simply use the Badge Configuration Utility to connect to
              each of your remaining badges.




                                                                   Configuring New Badges ··· 35

                     To configure the remaining badges:
                       1. From the Windows Start menu on the configuration computer, choose
                          Programs > Vocera > Badge Utilities > Badge Configuration Utility.
                          The Badge Configuration Utility opens in a command window, displaying a
                          list of firmware components and properties that the utility will download.
                       2. Attach a charged battery to a new badge.
                          The following events occur:
                          • The badge connects to the configuration computer.
                          • The Badge Configuration Utility downloads firmware and properties to
                            the badge.
                          • The Badge Configuration Utility appends the MAC address of the badge
                            to the end of the macaddr.txt file.
                          • The badge reboots and tries to connect to the production Vocera Server.
                          When the badge displays “Logged Out”, configuration is complete.
                       3. Continue configuring the remaining badges.
                       4. When you are finished, shut down the Badge Configuration Utility.
                          On the configuration computer, click the close icon in the upper-right
                          corner of the command window in which the Badge Configuration Utility is
                          running.
                          The Badge Configuration Utility session ends, and the command window
                          closes.


Configuring Badges with Static IP Addresses
                     You cannot use the Badge Properties Editor to assign static IP addresses,
                     because each static address must be unique. Therefore, each badge that uses
                     a static IP address must be configured manually. Because this is a slow and
                     potentially error-prone process, use a DHCP server to assign IP addresses to
                     badges whenever possible.
                     Use static IP addresses only in the following situations:
                     • You are setting up a small evaluation system.
                     • Static IP addresses are mandatory at your site.

                     To configure badges with static IP addresses:
                       1. Set up the configuration computer.
                          See Setting Up the Configuration Computer on page 39.

       Setting TCP/IP Properties on page 53:
      • Subnet Mask
      • Default Gateway
      • Preferred DNS
      • Alternate DNS
    c. Click OK to save these values and close the Badge Properties Editor.
4. Use the Badge Configuration Utility to download these shared properties to
   all the badges.
  See Configuring a Test Badge on page 33.
5. Use the vconfig utility to set the B2.BadgeIPAddr value of each B2000
   badge and the BadgeIPAddr value of each B1000A badge to different
   static IP addresses. Use standard dotted notation (for example, 192.168.3.7)
   to specify this value.

  Important: You must use vconfig to set this property manually on each
  badge.
  An online help system on the Vocera Server computer shows you
  how to use the vconfig utility. Open the help system by navigating to
  \vocera\config\help\vconfig\index.html in your browser.

Setting Up the Configuration Computer

         A badge requires basic configuration information, such as an SSID and security
         settings, to connect to your wireless network. Because a badge has no
         keyboard, you cannot configure it directly. Instead, you must configure it from a
         special computer called a configuration computer.
         A new badge is factory-programmed to establish a wireless connection
         to a computer with the IP address of 10.0.0.1 using an SSID of vocera (all
         lower-case), with open authentication and no encryption. After the badge
         connects to the configuration computer, you can use this computer to
         customize badge settings for your specific network requirements and security.
         The configuration computer must be a stand-alone computer that is not
         connected to your site's network. Here is the procedure for setting up the
         configuration computer:
          1. Install the Badge Utilities on the configuration computer. The Badge Utilities
             let you specify badge properties in a text file, then download the properties
             to your badges.
            See Installing the Badge Utilities on page 40.
          2. Assign a specific IP address (10.0.0.1) and subnet mask (255.0.0.0) to
             the configuration computer. When you boot a new badge, it looks for a
             computer with these properties that is running the Badge Configuration
             Utility.
            See Specifying TCP/IP Properties on page 41.
          3. Cable the configuration computer directly to an access point that is set
             up without security requirements. Any access point security will prevent
             unconfigured badges from connecting.
            See Setting Up an Isolated Access Point on page 41.
         Any notebook or desktop computer running Windows 2003 Server or Windows
         XP and containing an Ethernet network card is typically sufficient for use as the
         configuration computer.

  Installing the Badge Utilities


Installing the Badge Utilities
                        Vocera does not support more than one version of the Badge Utilities on a
                        configuration computer. The Badge Utilities version and Vocera server version
                        must be the same.
                        If the Badge Utilities from a previous version of Vocera are installed on the
                        configuration computer, remove them before installing the current Badge
                        Utilities. See Removing an Earlier Version of the Badge Utilities on
                        page 40.
                        If the Badge Utilities are not already installed on the configuration computer,
                        install them as described in Running the Badge Utilities Installation
                        Program on page 40.

Removing an Earlier Version of the Badge Utilities
                        If the Badge Utilities from a previous version of Vocera are installed on your
                        configuration computer, remove them before installing the current badge
                        utilities. By default, the Badge Utilities are installed in the \vocera\config
                        directory at the root of a drive that you specify.

                        To remove an earlier version of the Badge Utilities:
                         1. Log in to the computer with administrator privileges.
                         2. Choose Start > Control Panel > Add or Remove Programs.
                            The Add or Remove Programs dialog box appears.
                         3. Select Vocera Utilities.
                         4. Click Remove.
                            A dialog box asks you to confirm.
                         5. Click Yes.
                            A dialog box asks you to wait while the Badge Utilities are removed. It
                            closes when the operation is complete.

                   Next.
                5. Continue following the prompts in the installation program to install the
                   utilities.
                  Use the Help button on any screen for further information.


Specifying TCP/IP Properties
               You need to specify certain TCP/IP properties in the configuration computer to
               allow a new badge to connect to it properly.

               To specify TCP/IP properties:
               In Windows, use the Network Connections control panel to specify the
               following TCP/IP properties for the network card in your configuration
               computer:
               • Set the IP address to 10.0.0.1
                 When you boot a new badge, it automatically looks for a computer with this
                 address that is running the Badge Configuration Utility.
               • Set the Subnet mask to 255.0.0.0
               The exact procedure for setting your TCP/IP properties depends upon the
               version of the operating system. Refer to your Windows documentation for
               complete information.


Setting Up an Isolated Access Point
               To set up a badge, connect the configuration computer to an isolated access
               point—one that is not connected to the site’s network. The access point must
               be isolated from the rest of the network so you can set it up with a different
               SSID, and without compromising the site’s security.

  Setting Up an Isolated Access Point


                      This isolated access point allows a badge to connect to the configuration
                      computer using default factory settings. This access point is a temporary set up
                      that you use only to configure badges. Configured badges can connect to your
                      wireless LAN by using your existing SSID and security system.

                      To set up an isolated access point:
                        1. Attach an Ethernet crossover cable to the network port on the
                           configuration computer.
                        2. Connect the other end of the cable to the Ethernet port on the access
                           point.
                        3. If necessary, install configuration software for the access point on the
                           configuration computer.
                          Many access points require only a browser for configuration.
                        4. Using the access point configuration utility, make sure your access point is
                           set up as follows:
                          • Allow open authentication (typically the default)
                          • Turn off all security (typically the default)
                          • Assign the SSID value as vocera (using all lower-case letters)
                          • Allow a broadcast SSID to associate (typically the default)
                          • Configure as an access point in infrastructure mode (typically the default)
                          The exact procedure for setting up your access point depends upon the
                          hardware manufacturer. Refer to your access point documentation for
                          complete information.
                          When Vocera badges come from the factory, their SSID property is set either
                          to vocera or to <no value>. If you configure your access point as described
                          above, both types of badges can connect to it.
                      When you are finished, your badge configuration hardware should be set up as

   Creating a Property File to Download

              Badge properties tell a badge how to communicate on the wireless network
              deployed at your specific site. Use the Badge Properties Editor to create a
              badge.properties file specifying the property values your site requires,
              and then use either the Badge Configuration Utility or the Vocera Server to
              download these properties to all your badges.
              The badge.properties file used by the B2000 badge has the same file format
              as the file used by the B1000A badge. However, the B2000 provides some new
              properties that the B1000A does not support. See Badge Property Reference
              on page 83 and About Badge Profiles on page 45.

              Important: Many of the properties that you specify determine how your
              badges connect to your network and behave in your specific environment.
              You can optimize many network settings to improve badge performance, and
              configure your badge accordingly. See Vocera Infrastructure Planning Guide for
              information about how to configure your network infrastructure optimally to
              support the Vocera Communications System.


About Badge Profiles
              A badge profile is the set of properties that specifies how that badge connects
              to your network. B2000 and B1000A badges have independent profiles,
              allowing them to run on VLANs that have different network and security
              settings. Consequently, you can tune B2000 and B1000A badges independently
              to optimize their performance, or give them any combination of different
              property settings for specific purposes.
              For example, suppose all the 802.11g clients at your site are on a VLAN whose
              SSID is green, and your 802.11b clients are on the blue VLAN. You could create
              a profile for your B2000 badges that allows them to connect to the green SSID,
              and another profile for your B1000A badges allowing them to connect to the
              blue VLAN.

  About Badge Profiles


                     The properties used by the B2000 and B1000A have different names. In the
                     badge.properties file, all the properties used by the B2000 badge begin with a
                     "B2." prefix. Badge properties have the following naming conventions:
                     • If a B2000 property controls the same behavior as a B1000A property, the
                       only difference between the property names is the "B2." prefix.
                         For example, the B2000 and B1000A properties specifying the SSID that a
                         badge connects to are B2.SSID and SSID, respectively.
                     • If a B2000 property does not have a corresponding B1000A property, the
                       property name still begins with the "B2." prefix.
                         For example, the unique B2000 property that allows the badge to
                         take advantage of WMM when it is supported by your access points is
                         B2.EnableWMM. Because B1000A badges do not support this property,
                         there is not a corresponding B1000A EnableWMM property.
                     If you set all B2000 properties and their corresponding B1000A properties to
                     the same values, you create identical profiles for the two badge models. You
                     can also set B2000 and B1000A properties to different values.
                     For example, suppose your B1000A badges connect to the solar VLAN using a
                     pre-shared key, and you want your B2000 badges to connect to the lunar VLAN
                     using EAP-FAST. You could specify different profiles for the two badge models,
                     as shown in the following badge.properties fragment:

                    If you are deploying both badge models on the same subnet, make sure you
                    set the value of each B2000 property to the same value you are using for the
                    B1000A. The default values of these two B2000 properties are different to
                    reflect the more typical network environment at this time.
                    See Badge Property Reference on page 83 for a complete list of the

Using the Badge Properties Editor
                    The Badge Properties Editor is installed in the \vocera\config directory on
                    both the configuration computer and the Vocera Server computer. If you are
                    performing the initial badge configuration, run the Badge Properties Editor on
                    the configuration computer.

  Using the Badge Properties Editor


                      Note: You can use the Badge Properties Editor to specify properties for both
                      B1000A and B2000 badges. In addition, you can specify different network
                      profiles for your B1000A and B2000 badges, allowing them to reside on
                      different VLANs. See About Badge Profiles on page 45.

                      To use the Badge Properties Editor:
                       1. From the Windows Start menu, choose Programs > Vocera > Badge
                          Utilities > Badge Properties Editor.
                          The Badge Properties Editor appears.
                       2. Set property values as described in the following topics:
                          • Setting General Properties on page 49 describes the minimal set of
                            properties you need to set for any badge in use at your site.
                          • Setting Security Properties on page 50 describes how to make
                            badges work with the security features implemented on your wireless
                            network.
                          • Setting TCP/IP Properties on page 53 describes the IP settings that
                            a badge can use.
                          • Setting Advanced Properties on page 55 describes a small set of
                            properties that are used in special situations.
                          The Badge Properties Editor creates a text file called badge.properties in
                          \vocera\config.
                      After you create the badge.properties file, you can upload the property values
                      it contains to your badges.
                      • If you are configuring new badges, use the Badge Configuration Utility to
                        download properties to the badges.
                        See Using the Badge Configuration Utility on page 59.
                      • If you are updating badges that are already connected to a Vocera Server, use
                        the Vocera Server to download properties to the badges.
                        See Maintaining Properties and Firmware on page 79.

                      Note: Use the Badge Properties Editor to create and modify the
                      badge.properties file instead of using a text editor. Some values in
                      badge.properties are encrypted; in addition, other properties are
                      case-sensitive or accept only a limited range of values. Using the Badge
                      Properties Editor reduces the likelihood of creating incorrect property names or
                      values.

Setting General Properties
                 The general properties comprise the minimal set of properties needed by
                 any badge at your site. You must set values for all the general properties.
                 Depending on the configuration of your site, you may have to set other
                 properties as well.

                 Table 6. General properties

                  Property             Description

                  Badge Type           Specify whether you are creating properties for B1000A badges
                                       or B2000 badges. When your environment has both badge
                                       models in use, do the following:
                                        1. Choose B1000A.
                                        2. Set all the properties needed by the B1000A profile.
                                        3. Click Apply to save these values without closing the Badge
                                           Properties Editor.
                                        4. Choose B2000.
                                        5. Set all the properties needed by the B2000 profile.

                  SSID                 Use the SSID field to specify the SSID of the wireless network
                                       or subnet the Vocera badges will use. This is a required field.
                                       This value is case sensitive, and can be up to 32 characters in
                                       length. You can use initial or embedded spaces in the SSID
                                       value; trailing spaces cause an error message when the value is
                                       saved.

                                       Best Practice: Specify an SSID other than vocera (all
                                       lower-case) for your production server. Badges are
                                       factory-programmed to use the vocera SSID to establish a
                                       wireless connection to the configuration computer that you
                                       have set up for your Vocera system.

                  Vocera Server IP     Use the Vocera Server IP Address field to specify the IP
                  Address              address of the computer which is running the Vocera server.
                                       This is a required field.
                                       Use dotted notation (such as 192.168.3.7) to specify this value.
                                       If you are configuring a cluster, enter the IP address of each
                                       machine in the cluster, separated by commas, with no spaces.
                                       The badge supports a maximum of 63 characters for the
                                       members of the cluster list. This limit allows you to enter four
                                       numeric IP addresses, separated by commas, with no spaces
                                       between them.

Setting Security Properties
                       Set badge security properties that correspond to the type of authentication and
                       encryption employed by your wireless network.
                       If you are deploying both B2000 and B1000A badges, you can configure them
                       to reside on separate VLANs and take advantage of the enhanced security
                       support of the B2000. If all your badges reside on the same VLAN, the security
                       you choose must be supported by both badge models. See About Badge
                       Profiles on page 45 for information about configuring badges on separate
                       VLANs.
                       For more information about the security systems supported by Vocera, see

 Badge Type           Specify whether you are creating properties for B1000A badges
                      or B2000 badges. When your environment has both badge
                      models in use, do the following:
                        1. Choose B1000A.
                        2. Set all the properties needed by the B1000A profile.

                        5. Set all the properties needed by the B2000 profile.

 Authentication       In the Authentication field, specify whether your wireless
                      network requires authentication for access:
                      • Specify Open if your wireless network does not require
                        authentication.
                      • If your wireless network requires authentication, specify the
                        corresponding protocol.
                      Important: If you are using EAP-FAST authentication, you
                      must also create a .pac file. See Configuring EAP-FAST
                      Authentication on page 112.

 User Name,           If your network uses either LEAP, WPA-PEAP, or EAP-FAST
 Password             authentication with TKIP-WPA encryption, enter appropriate
                      values in the User Name and Password fields. Otherwise, skip
                      these fields.
                      Each badge on a Vocera server must use the same user name
                      and password for LEAP, WPA-PEAP, or EAP-FAST authentication.
                      The user name format depends on requirements set by the
                      RADIUS authentication server. For example, when using
                      LEAP with Cisco ACS and Windows Active Directory, enter
                      domain\userid in the User Name field, where domain is a
                      Windows domain name and userid identifies the user. Other
                      RADIUS servers may require the user name only.
                      The password value is case sensitive. You can use initial or
                      embedded spaces in either of these values; trailing spaces
                      cause an error message when the values are saved.
                      The badge supports a maximum of 32 alphanumeric characters
                      for both the User Name and the Password. In addition, the
                      badge supports the following characters for LEAP passwords:
                      ^ # ! * @ % & $

                  badges transmit data using hexadecimal keys. WEP uses 64-bit or 128-bit keys
                  (sometimes called 40-bit or 104-bit keys, respectively) to encrypt and decrypt
                  data. Each device transmits and receives using a hexadecimal key in one of four
                  possible positions. The position used to transmit and receive is not necessarily
                  the same.
                  To successfully transmit data, the position and value of the key used to transmit
                  must match the position and value of the key in the receiving device. The
                  position that the access point uses to transmit is not necessarily the same as the
                  position that the badge uses to transmit. However, the value that the access
                  point uses to transmit must match the value you supply for the corresponding
                  position of the badge.
                  For example, if an access point uses its first encryption key to transmit data,
                  you must configure the badges to use that same hexadecimal value in the first
                  position. Similarly, if the badges use their third WEP key to transmit data, the
                  third WEP key stored in the access point must have a matching encryption key
                  value.
                  You do not have to specify values for each of the four WEP keys, only the keys
                  that the access point and badge actually use to transmit data. However, the
                  best practice is to make sure that the values of the keys in all four positions
                  match. That way, if a security administrator changes the position that the access
                  point uses to transmit, the badges will continue to work.

Setting TCP/IP Properties
                  The TCP/IP properties specify whether badges are assigned IP addresses
                  dynamically by a DHCP server, or whether each badge has a static IP address.
                  Use a DHCP server to assign IP addresses to the badges whenever possible.
                  Static IP addresses are feasible only for small evaluation systems. Because using
                  a static IP address for each badge requires manual configuration, it is a slow and
                  error-prone process for large numbers of badges.

                        Badge Type            Specify whether you are creating properties for B1000A badges
                                              or B2000 badges. When your environment has both badge
                                              models in use, do the following:
                                               1. Choose B1000A.
                                               2. Set all the properties needed by the B1000A profile.

                                               5. Set all the properties needed by the B2000 profile.

                        Use DHCP Settings     Choose Use DHCP Settings if your site uses a DHCP server to
                                              provide IP addresses dynamically.
                                              Most sites use a DHCP server for IP addresses. This choice is the
                                              default.

                        Use Static Settings   Choose Use Static Settings if you want to specify specific
                                              static IP addresses.
                                              Use static addresses for small evaluation systems only, because
                                              you must set each IP address manually with the Vconfig utility.
                                              You cannot set static IP addresses in the Badge Properties
                                              Editor. See Configuring Badges with Static IP Addresses on
                                              page 36.

                        Subnet Mask           Use the Subnet Mask field to specify which bits in the IP
                                              address correspond to the subnet.

                        Default Gateway       If your LAN uses a gateway to connect to other networks, enter
                                              its dotted notation address in the Default Gateway field.
                                              This value is necessary only if the Vocera Server resides on a
                                              different subnet than the badges.

                        Preferred DNS         Use the Preferred DNS field to enter the IP address of the DNS
                                              server that your site uses to resolve DNS queries, if the value of
                                              the Vocera Server IP Address field in the General properties
                                              page is specified as a DNS name.

                        Alternate DNS         Use the Alternate DNS field to enter the IP address of the
                                              secondary DNS server, if the value of the Vocera Server IP
                                              Address field in the General properties page is specified as a
                                              DNS name. The secondary DNS server is used if the primary
                                              DNS server is not available.

                 Badge Type            Specify whether you are creating properties for B1000A badges
                                       or B2000 badges. When your environment has both badge

                                         5. Set all the properties needed by the B2000 profile.

                 Subnet Roaming        Check Subnet Roaming only if the access points on your
                                       wireless LAN are divided into multiple subnets, and if you
                                       want to allow users to roam across subnet boundaries. The
                                       subnet where the Vocera server is located is not relevant to this
                                       property.
                                       If you allow subnet roaming, you use a DHCP server to
                                       supply your IP addresses. See Setting TCP/IP Properties on
                                       page 53 for information about configuring Vocera with a
                                       DHCP server.
                                       If all access points on your wireless LAN are on the same
                                       subnet, leave Subnet Roaming disabled to minimize DHCP
                                       traffic and to reduce the chance of a momentary loss of audio
                                       when roaming between access points.
                                       This property is available for both B1000A and B2000 badges.

                       Property         Description

                       Roaming Policy   The Roaming Policy property specifies how quickly a badge
                                        searches for an access point when signal quality drops. Higher
                                        values cause a badge to search sooner, and may correct
                                        problems with choppy audio. However, a badge cannot send
                                        or receive audio packets while searching for an access point,
                                        so communication may be interrupted. Lower values allow a
                                        badge to tolerate lower signal quality before searching. The
                                        optimal threshold value varies from one 802.11 network to
                                        another, depending on how the network is configured. The
                                        default value is 2.
                                        This property is available for both B1000A and B2000 badges.

                       Broadcast Uses   Use the Broadcast Uses IGMP field to specify whether you
                       IGMP             want badges to use Internet Group Management Protocol. If
                                        your want broadcast and push-to-talk commands to function
                                        across multiple IP subnets, IGMP must be supported in the
                                        switch or router, and this property must be enabled (checked).
                                        This property is available for both B1000A and B2000 badges.

                       Short Preamble   Use the Short Preamble (802.11 Frame) field to specify
                       (802.11 Frame)   whether you want B1000A badges to transmit with a short or
                                        long preamble.
                                        By default, the B1000A badge transmits with a long preamble.
                                        Check Short Preamble only if you must optimize bandwidth.
                                        This property is not available for the B2000 badge, which
                                        always transmits with a short preamble.

                       Scan Default     The B1000A badge uses the setting you make in the Scan
                       Channels         Default Channels field to optimize roaming. When you check
                                        this property, the badge first scans channels 1, 6, and 11 as
                                        its signal drops. If the badge is unable to connect to an access
                                        point on one of these channels, it then scans all available
                                        channels.
                                        For optimal performance of the badge and other wireless
                                        clients, Vocera recommends that the access points on your
                                        network are set only to the three non-overlapping channels of
                                        1, 6, and 11. If your network uses only channels 1, 6, and 11,
                                        check the Scan Default Channels field.
                                        The Scan Default Channels setting is available for B1000A
                                        badges only.

Property   Description

802.11d    Use the 802.11d field to specify whether you want B2000
           badges to select AP channels based on the country code
           broadcast by access points and on the Channels To Scan
           property.
           By default, this property is not selected. In order to take
           advantage of this feature, your access points must also support
           it. This property is not available for the B1000A badge.

APSD       Use the APSD field to specify whether you want to enable
           Automatic Power Save Delivery (APSD) power management.
           APSD potentially increases the talk time of 802.11 clients.
           By default, this property is not selected. In order to take
           advantage of this feature, your access points must also support
           it. This property is not available for the B1000A badge.

WMM        Use the WMM field to specify whether you want to enable
           WMM (the WiFi Multimedia subset of 802.11e).
           WMM provides standards-based QoS to prioritize voice over
           data traffic and ensure high level voice quality. The B2000
           badge allows you to use WMM to prioritize packets.
           By default, this property is not selected. In order to take
           advantage of this feature, your access points must also support
           it. This property is not available for the B1000A badge.

CCKM       Use the CCKM field to specify whether you want to enable
           Cisco Certified Key Management.
           CCKM is a form of fast roaming supported on Cisco access
           points and on various routers. Using CCKM, Vocera devices can
           roam from one access point to another without any noticeable
           delay during reassociation. After a Vocera device is initially
           authenticated by the RADIUS authentication server, each
           access point on your network acts as a wireless domain service
           (WDS) and caches security credentials for CCKM-enabled client
           devices. When a Vocera device roams to a new access point,
           the WDS cache reduces the time it needs to reassociate.
           By default, this property is not selected. In order to take
           advantage of this feature, your access points must also support
           it, and you must use either LEAP, WPA-PEAP, or EAP-FAST
           authentication. This property is not available for the B1000A
           badge.

                     Enabling 802.11d
                     If you enable 802.11d in B2000 badges and you roam with a badge to an
                     access point that does not have 802.11d enabled, the badge will passively scan
                     for beacons to discover what country it's in. If it finds beacons but the beacons
                     do not identify the country, the badge will display the following message:
                     COUNTRY INFO NOT FOUND IN BEACONS
                     If this happens, press the Call button to clear the message, and then make sure
                     that 802.11d is enabled on all access points.

   Using the Badge Configuration Utility

               The Badge Configuration Utility is a tool that can download properties and
               firmware from the configuration computer to:
               • New badges that have never been configured.
               • Badges that have been reset to factory defaults.
                 See How to Restore Factory Settings on page 77.
               Because the Badge Configuration Utility is used with new badges, it must
               run on a stand-alone configuration computer. Each badge uses a built-in
               program called Updater during initial configuration. By default, the Updater
               program scans channels 1 through 11 attempting to connect to a Badge
               Configuration Utility on a machine whose IP address is 10.0.0.1. See Setting
               Up the Configuration Computer on page 39.
               After the badge downloads its properties and firmware, it reboots and attempts
               to connect to the network using the property values it has downloaded. If it
               connects to the network successfully, it then attempts to connect to the Vocera
               Server specified in either its B2.ServerIPAddr or its ServerIPAddr property.

               Note: The Badge Configuration Utility performs different actions when it
               configures B2000 and B1000A badges, as described in About the Badge
               Configuration Utility on page 59. However, these actions are all internal
               to the Badge Configuration Utility, so you can configure B2000 and B1000A
               badges simultaneously.


About the Badge Configuration Utility
               The \vocera\config directory on the configuration computer contains all the
               files used by the Badge Properties Editor and the Badge Configuration Utility.
               By default, the same set of files is also installed in this directory on the Vocera
               Server computer.

                Although you can configure B2000 and B1000A badges simultaneously,
                the Badge Configuration Utility performs slightly different actions during
                configuration. The following sections describe the Badge Configuration Utility
                behavior with each badge model:
                • The Badge Configuration Utility and the B2000 on page 61
                • The Badge Configuration Utility and the B1000A on page 64

The Badge Configuration Utility and the B2000
                When you start either the Badge Configuration Utility or the Vocera Server,
                they both auto-generate data used by the B2000 badge. Specifically, each
                application:
                • Creates the \vocera\config\gen2\metadata\filelist file.
                  See The filelist File on page 62.
                • Hashes the \vocera\config\gen2\metadata\filelist file to calculate a
                  MasterHash value.
                • Does one of the following:
                  • If badge.properties exists, copies it to create the
                    badge.properties.server file, and appends the MasterHash property and
                    value to the end of badge.properties.server.
                  • If badge.properties does not exist, creates a zero-length
                    badge.properties file, copies it to create the badge.properties.server
                    file, and appends the MasterHash property and value to the end of
                    badge.properties.server.
                  See The badge.properties.server File on page 63.

  The Badge Configuration Utility and the B2000


                     The filelist File
                     The filelist file contains a record for every file in the badge directory tree.
                     The badge uses the information in filelist to determine what firmware and
                     properties it needs to download to synchronize itself with the configuration
                     computer.
                     Each record in filelist has three fields containing the following information:
                     • The file name and path, relative to \vocera\config\gen2.
                     • The file size, in bytes.
                     • The file hash, a digital fingerprint used to identify the exact version of the file.
                     The following illustration shows the content of a typical filelist file.

                     Figure 15. Content of filelist file




                     When the badge connects to the Badge Configuration Utility, filelist is the first
                     file it downloads. The badge checks each record in filelist sequentially. The
                     information in filelist provides redundant checks to help ensure that the badge
                     and the server are synchronized:
                     • If a file appears in filelist, but not on the badge, the badge requests it from
                       the Badge Configuration Utility.

                                      The Badge Configuration Utility and the B2000


• If the size of a file in filelist is different than the size of the file on the badge,
  the badge requests it from the Badge Configuration Utility.
• If the hash of a file in filelist is different than the hash of the file on the
  badge, the badge requests it from the Badge Configuration Utility.
The first records in filelist identify the files in the Linux operating system used
by the badge. The badge.properties.server file is the last record in filelist,
and is consequently the last file downloaded by the badge.
If the badge loses its connection with the Badge Configuration Utility for any
reason during the update process, it restarts its Updater program and continues
until it downloads the last file in filelist.

The badge.properties.server File
The B2000 uses badge.properties.server to create or maintain its own
badge.properties file. After the badge downloads badge.properties.server,
it does the following:
• Creates a badge.properties file on the badge, if it does not already exist.
• Adds any new properties and values that are in badge.properties.server to
  the list in badge.properties.
• Updates badge.properties with any values that are different in
  badge.properties.server.
Properties that are auto-generated by the Badge Configuration Utility appear at
the end of badge.properties.server, as shown in the following illustration:

                     Figure 16. Auto-generated badge properties




                     The last property in badge.properties.server is the auto-generated
                     MasterHash. The Badge Configuration Utility does not use MasterHash; it is
                     used by the Vocera Server to keep badges in sync with itself. See Maintaining
                     Properties and Firmware on page 79.

The Badge Configuration Utility and the B1000A
                     In contrast to the B2000, the B1000A downloads .fci firmware files from the
                     \vocera\config\fci directory and badge.properties only.
                     When the B1000A connects to the Badge Configuration Utility, the application
                     checks to see if any .fci file is missing or different on the badge. If it is, the
                     badge downloads the necessary .fci files from the Badge Configuration Utility.
                     The Badge Configuration Utility then reads badge.properties into memory,
                     hashes it to create a digital fingerprint, stores the hash as the value of the
                     PropertyVersion property, and appends this virtual property to the version of
                     badge.properties it has in memory.

                                                        Running the Badge Configuration Utility


               The Badge Configuration Utility checks one property at a time, and the badge
               downloads any properties that are missing or different. When the badge
               downloads the PropertyVersion hash, the update is complete and the badge
               reboots.
               If the badge loses its connection with the Badge Configuration Utility for any
               reason during the update process, it restarts its Updater program and continues
               until it downloads PropertyVersion.


Running the Badge Configuration Utility
               To use the Badge Configuration Utility:
                1. From the Windows Start menu on the configuration computer, choose
                   Programs > Vocera > Badge Utilities > Badge Configuration Utility.
                  The Badge Configuration Utility opens in a command window, listing the
                  B1000A .fci files, followed by each value in badge.properties, followed by
                  B2000 information.

                  Figure 17. Badge Configuration Utility start-up




                2. Attach a charged battery to either a new badge or a badge that has been
                   reset to factory defaults.
                  The badge automatically runs its Updater program because the InstallDone
                  property is set to False. Updater looks for a Badge Configuration Utility
                  running on 10.0.0.1 and connects to it.

  Running the Badge Configuration Utility


                       3. The Badge Configuration Utility displays the start session message, and
                          then the badge automatically starts the download process.
                       4. The Badge Configuration Utility identifies the model of the badge:
                          • If the badge is a B2000, it downloads filelist from the Badge
                            Configuration Utility and updates itself as described in The Badge
                            Configuration Utility and the B2000 on page 61.
                          • If the badge is a B1000A, it downloads the files in \vocera\config\fci
                            and the badge.properties file from the Badge Configuration Utility, if
                            necessary.
                            See The Badge Configuration Utility and the B1000A on page 64.
                       5. The Badge Configuration Utility continues to display messages as the badge
                          downloads firmware and properties. When the download is complete,
                          the Badge Configuration Utility displays the message end session and
                          appends the MAC address of the badge to the macaddr.txt file in the
                          \vocera\config directory.
                       6. The badge automatically reboots and tries to connect to the network, using
                          the SSID and other network properties that it downloaded.
                          If successful, the badge tries to connect to the Vocera Server that was
                          specified in the ServerIPAddr property.
                       7. Look at the screen of the badge:
                          • The message “Logged Out” indicates that the badge is configured
                            properly and has connected to the Vocera Server.
                            Continue with Configuring the Remaining Badges on page 35.
                          • If the badge does not display “Logged Out” within 30 seconds to one
                            minute, the badge is not configured properly and did not connect to the
                            Vocera Server
                            Continue with Troubleshooting Badge Configuration on page 67.
                       8. Shut down the Badge Configuration Utility.
                          On the configuration computer, click the close icon in the upper-right
                          corner of the command window in which the Badge Configuration Utility is
                          running.
                          The Badge Configuration Utility session ends, and the command window
                          closes.

               • Troubleshooting the Initial Badge Configuration on page 67.
                 If a badge is not communicating properly after its initial configuration, this
                 topic helps you determine where the problem is occurring.
               • Troubleshooting the Badge Property Settings on page 69.
                 If the communication problem is internal to the badge, this topic shows you
                 how to change badge property settings.

               • Restoring Factory Settings on page 76.
                 If you cannot troubleshoot your badge, or if you think it is so badly
                 configured that you cannot proceed, you can restore it to its original factory
                 settings and try to configure it again.


Troubleshooting the Initial Badge Configuration
               If you complete the steps described in Configuring a Test Badge on page 33
               and the screen of the test badge does not display the “Logged out” message,
               you need to troubleshoot it. The badge may not be configured properly, or
               there may be a problem with some of the other hardware and software you are
               using.
               When the badge does not successfully connect to the production Vocera Server
               at the end of its configuration cycle, one or more of the following problems
               may have occurred:
               • The production Vocera Server is not running
               • The badge is not within range of an access point used by the production
                 server

                                    because:
                                    • The Vocera Server is not running.
                                      Make sure the Vocera Server is running, then remove the

                                    • The subnet that the badges are on cannot reach the subnet
                                      that the Vocera server is on. This situation can occur if you
                                      have set up an isolated subnet for the badges.
                                      Make sure the switch and router settings allow the badge
                                      subnet access to the server subnet, then remove the battery

Troubleshooting the Badge Property Settings
              Troubleshooting the badge property settings is an iterative process. If you did
              not successfully configure a badge the first time, you can reset the factory
              defaults and configure the badge again. You can repeat this process as many
              times as necessary.

              To troubleshoot badge properties:
               1. Display the badge configuration menus.
                 See Displaying the Badge Configuration Menu on page 70.
               2. Reset all the badge properties to the factory default settings.
                 See Restoring Factory Settings on page 76.
               3. Launch the Badge Properties Editor again.
                 When you launch the Badge Properties Editor after the initial configuration,
                 it reloads your working settings from the badge.properties file. See Using
                 the Badge Properties Editor on page 47 for information about launching
                 the Badge Properties Editor.
               4. Use the Badge Properties Editor to change the incorrect property values.

  Using the Badge Configuration Menu


                         Refer to the table in Troubleshooting the Initial Badge Configuration
                         on page 67 for hints about what property values are incorrect. Then
                         change the values as described in Using the Badge Properties Editor on
                         page 47.
                       5. Configure the badge by running the Badge Configuration Utility again.
                         See Configuring a Test Badge on page 33.


Using the Badge Configuration Menu
                     The badge configuration menu lets you access a set of diagnostic
                     and configuration tools that are built into the badge. These tools are
                     powerful—they are intended only for use when troubleshooting badge
                     configuration.
                     The following topics describe how to use the badge configuration menus:
                     • Displaying the Badge Configuration Menu on page 70
                     • Navigating in the Badge Configuration Menu on page 75

Displaying the Badge Configuration Menu
                     Do not confuse the badge configuration menu with the top-level badge menu:
                     • The configuration menu contains utilities for configuration and
                       troubleshooting, and it is only available before the badge fully boots.
                     • The top-level menu contains information and controls for end users, and it is
                       only available after the badge fully boots.
                     The procedures for displaying the configuration menu in the B1000A and
                     B2000 badges are similar, although the screens displayed by each are different.
                     The following sections illustrate the steps for each badge model:
                     • Displaying the B2000 Configuration Menu on page 70
                     • Displaying the B1000A Configuration Menu on page 73

                     Displaying the B2000 Configuration Menu
                     Because badge users should not have access to the badge utilities, make sure
                     that the configuration menus are hidden before distributing badges to users.
                     The Hide Boot Menus property determines whether the badge configuration
                     menus are hidden, or if they can be easily accessed through the Hold/DND
                     button. See Setting General Properties on page 49.

Navigating in the Badge Configuration Menu
                Because the screen of the badge is small, all the menu items are not visible at

                or you can select a menu item to view a nested set of items related to the
                upper-level menu choice.
                Use the following buttons to navigate in the badge menus:
                • The Scroll Up button (the top button on the side of the badge)
                  Press this button to scroll up through menu items.
                • The Scroll Down button (the bottom button on the side of the badge)
                  Press this button to scroll down through menu items.
                • The Select button (the middle button on the side of the badge)
                  Press this button to select a menu item. Depending on the selection you
                  make, any of the following things can happen:
                  • A lower-level set of menu items appears.
                  • An action occurs (such as connecting to the vconfig utility).
                  • A value is set (such as TRUE or FALSE).
                • The Call button (the big button on the front of the badge)
                  Press this button to navigate to an upper-level set of menu items. If you
                  are already in the top-level set of menus, pressing the Call button does not
                  navigate further.

Restoring Factory Settings
                      When you use the Badge Configuration Utility, you download property values
                      that specify how a badge connects to your network and the way it will behave
                      when it is connected. If one or more of these values are incorrect, you can
                      restore all the factory default settings and configure the badge again.
                      The following topics explain how to restore a badge’s factory default settings.
                      • About the InstallDone Property on page 76
                      • How to Restore Factory Settings on page 77

About the InstallDone Property
                      InstallDone is a hidden property that the Badge Configuration Utility uses. You
                      cannot set the value of the InstallDone property in the Badge Properties Editor.
                      By default, InstallDone is set to FALSE in a new badge that you receive from
                      the factory. The Badge Configuration Utility sets this property to TRUE when it
                      successfully downloads badge firmware and properties.

                 If InstallDone is FALSE, a badge automatically looks for the configuration
                 computer (the IP address 10.0.0.1) when it powers up. If InstallDone is TRUE,
                 the badge boots normally and connects to the Vocera server. When you restore
                 factory settings, you also set InstallDone to FALSE, which lets you use the
                 Badge Configuration Utility a second time.

How to Restore Factory Settings
                 Before you can reuse the Badge Configuration Utility on a badge, you must
                 restore the badge’s factory default settings.

                 To restore the factory settings on the B2000:
                  1. Display the badge configuration menu.

78 ··· Vocera B2000 Badge Guide
Maintaining Properties and Firmware

         You can use the production Vocera Server to change badge properties or
         update firmware any time after the initial badge configuration, instead of using
         the configuration computer. This is convenient because the Vocera Server can
         update connected badges automatically, without requiring you to configure
         them manually again.
         For example, a service pack may contain firmware updates that you need
         to implement, or you may need to change values in badge.properties to
         accommodate your evolving network needs. In either of these cases, the Vocera
         Server can download the necessary files to any connected badges and update
         them.

         Note: Although the production Vocera Server can update your existing
         badges, you should continue to maintain the configuration computer after
         you complete the initial badge configuration. You will need the configuration
         computer to configure any new badges that you receive.
         When the Vocera Server downloads firmware or the badge.properties file, the
         badge notifies the user by saying, “I am updating the software in your badge. It
         may take a few minutes”. When the download finishes, the badge notifies the
         user by saying, “Update complete.”
         Users cannot place or receive calls while their badges are being updated. Any
         badges that are off network at the time will automatically be updated as soon
         as they boot and connect to the server.

         Best Practice: Copy the badge.properties file from the \vocera\config
         directory on the configuration computer to the same directory on the
         production Vocera Server after you complete the initial badge configuration.
         You can use this file as a reference to see what property values the badges are
         currently using. In addition, if you need to change badge properties later, the
         Vocera Server uses this file to update the badges automatically.

  About Property and Firmware Maintenance


                     The rest of this chapter explains how to use the Vocera Server to maintain
                     badges. See Configuring New Badges on page 33 for information about
                     setting badge properties for the first time.


About Property and Firmware Maintenance
                     The Vocera Server maintains a copy of the most recent badge firmware in its
                     own directory structure in the following locations:
                     • For the B2000 badge, in the \vocera\config\gen2\badge directory tree.
                     • For the B1000A badge, in the \vocera\config\fci directory.
                     The Vocera Server can update badge properties and firmware at either of the
                     following times:
                     • Immediately after a badge boots.
                        When a badge boots, it connects to the Vocera Server. The server compares
                        the badge firmware and properties with its own copies as described in
                        Updating Properties and Firmware on page 80.
                     • Immediately after the server starts.
                        You need to stop the server to install any upgrades or service packs that
                        may contain new firmware. When you restart the server, it compares the
                        badge firmware and properties with its own copies as described in Updating
                        Properties and Firmware on page 80.
                     The server downloads firmware even if a badge has a more recent version of
                     the firmware than the server. If you receive a firmware upgrade from Vocera,
                     install it on the Vocera server as described in the firmware service pack.


Updating Properties and Firmware
                     Each time the Vocera Server starts, it reads badge.properties into memory.
                     If property values on the badge don’t match the in-memory values, the server
                     automatically updates the badges with the values from badge.properties.

                     Important: If you edit the badge.properties on the Vocera Server, its values
                     are not read into memory again until you restart the server. At that time, the
                     server automatically downloads the new properties to badges that connect to
                     it.

                     To update properties and firmware:
                       1. Use the Badge Properties Editor to update the badge.properties file in the
                          \vocera\config directory on the computer running the Vocera Server.

  See Using the Badge Properties Editor on page 47.
2. Use the Vocera Control Panel to restart the server, as described in Using the
   Vocera Control Panel in the Vocera Configuration Guide.
  The Vocera Server does the following:
  • Creates the filelist file, hashes it, and creates the
    badge.properties.server file.
    See The Badge Configuration Utility and the B2000 on page 61.
  • Reads badge.properties into memory, hashes it, and appends the hash
    value as a virtual property in the version of badge.properties it has in
    memory.
    See The Badge Configuration Utility and the B1000A on page 64.
3. As badges connect to the server, the following events occur:
  • If the badge is a B2000, it downloads filelist and checks the values in
    that file, synchronizing itself with the Vocera Server if necessary.
    See The Badge Configuration Utility and the B2000 on page 61.
  • If the badge is a B1000A, the server makes sure the badge's firmware
    and properties are the same as its own. The badge downloads any
    firmware and properties that it needs to synchronize itself with the server.
    See The Badge Configuration Utility and the B1000A on page 64.
  If a badge is offline, these events occur as soon as the badge boots and
  connects to the server.

Badge Property Reference

         This section contains an alphabetical list of the most common badge properties.
         These property names appear in the badge.properties file and when you
         connect to a badge with the Vconfig utility. The list contains cross-references to
         the fields and pages you can use to set these properties in the Badge Properties
         Editor (BPE).

         Important: Badges have many properties that are for internal use only. Be
         careful using Vconfig. Setting the wrong value or the wrong property can
         cause unrecoverable damage to a badge. Use the Badge Properties Editor to set
         property values unless you are working with Vocera Technical Support. Do not
         use Vconfig to set any properties other than the ones listed in this chapter.
         For more information about the Vconfig utility, view its help system by
         navigating to \vocera\config\help\vconfig\index.htm in your browser.

 Not available                        is enabled for Vocera devices.

• B2000:                              CCKM is a form of fast roaming supported on
                                      Cisco access points and on various routers. Using
 B2.EnableCCKM                        CCKM, Vocera devices can roam from one access
                                      point to another without any noticeable delay
                                      during reassociation. After a Vocera device is initially
                                      authenticated by the RADIUS authentication server,
                                      each access point on your network acts as a wireless
                                      domain service (WDS) and caches security credentials
                                      for CCKM-enabled client devices. When a Vocera
                                      device roams to a new access point, the WDS cache
                                      reduces the time it needs to reassociate.

                                     5, the default listen interval is 500 ms.
                                     The B1000A badge uses PrismSleepTime property,
                                     set to 500 ms by default, to control the same

Property Name    Default Value   Description

• B1000A:        FALSE           In the B1000A badge, specifies whether you want
 ShortPreamble                   badges to transmit with a short or long preamble.

• B2000:                         The 802.11 specification provides for both short and
                                 long preamble settings for frames. Short preambles
 Not available                   use slightly less bandwidth; however, some access
                                 points do not support short preambles.
                                 Set this value as follows:
                                 • Set this property to FALSE, the default, if you
                                   want the Vocera badge to use a long preamble.
                                 • Set this property to TRUE only if you must
                                   optimize bandwidth, and if you are certain that

              • Access Point Settings on page 98.

802.11b/g Support
              The B2000 badge supports both 802.11b and 802.11g. The B2000 badge
              cannot be configured to use either 802.11b or 802.11g data rates; it
              automatically uses the 802.11b and 802.11g data rates that have been enabled
              on the access points. For optimal coverage, Vocera recommends that you
              enable all 802.11b and 802.11g data rates on the access points.
              The B1000A badge is an 802.11b client. It is compatible with 802.11b access
              points or 802.11g access points that are configured in either of the following
              ways:
              • To support 802.11b clients only.
              • To support a mixed 802.11b and g environment.
              A mixed 802.11b and g environment, rather than a dedicated 802.11g
              environment, lowers the throughput for your 802.11g clients, but it still
              provides them with better throughput than a dedicated 802.11b environment.

Data Rates
                      For optimal reliability, Vocera recommends that you enable all 802.11b/g data
                      rates on your network. When all data rates are enabled, the badge can switch
                      among them if necessary to maintain a connection, minimizing the likelihood
                      of lost packets. You must also set one or more data rates as Basic. See Data
                      Rates and Overlapping Cells in the Vocera Infrastructure Planning Guide and
                      Configuring AP Radio Data Rates in the Vocera Infrastructure Planning Guide

SSID and Security
                    The badges are centrally maintained by the Vocera server from a single
                    configuration file. Because the badge does not have a keyboard, this centralized
                    management is practical and minimizes maintenance that would otherwise be
                    time-consuming and error-prone.

                    Note: You can use the Badge Properties Editor to specify properties for both
                    B2000 and B1000A badges. In addition, you can specify different network
                    profiles for your B2000 and B1000A badges, allowing them to reside on
                    different VLANs.

                    To configure badge SSID and security settings:
                     1. Use the Badge Properties Editor to specify the SSID of the badge VLAN.
                       See Setting General Properties on page 49.
                     2. Use the Badge Properties Editor to specify the security requirements of the
                        badge VLAN.
                       See Setting Security Properties on page 50.
                    See Security on page 105 for additional information about configuring
                    badge security.


Acceptable Voice Quality
                    Vocera B2000 and B1000A badges provide different utilities for evaluating the
                    communication quality of the signal you are receiving from an access point.
                    Both survey tools use a logarithmic scale to measure communication quality,
                    but the values are normalized differently. Consequently, communication quality
                    is measured in SNR (for Signal-to-Noise Ratio) on a B2000 badge and in CQ
                    (for Communication Quality) on a B1000A badge. An SNR value is similar but
                    not equivalent to a CQ value. The SNR and CQ values are not equivalent to
                    traditional SNR values, which are normally measured in decibels. Instead, SNR
                    and CQ values are based on a logarithmic scale ranging from 0 to 92, where 0
                    represents no signal and 92 is the strongest possible signal with essentially no
                    background noise.
                    Depending on what type of Vocera badge you have, use the appropriate tool
                    to confirm that your access point coverage is sufficient to support the badge
                    in all areas where it will be used. The Vocera system can maintain good voice
                    quality in all places where the SNR value is greater than or equal to 16 and the
                    CQ value is greater than or equal to 20.



                                                                          B2000 Wireless Features ··· 99
  Acceptable Voice Quality


                     The Vocera utilities for evaluating communication quality are Layer 2
                     applications that do not require the badge to connect to the Vocera server
                     or to acquire an IP address. Consequently, you can use it to confirm network
                     coverage early in the implementation process, before the Vocera system is
                     physically deployed.

                     Note: To use the B1000A badge in survey mode, you must make sure that the
                     badge VLAN at least temporarily allows open authentication while you conduct
                     the survey. The B2000 badge survey tool does not require open authentication.

                     To confirm communication quality levels throughout a site using a
                     B2000 badge:
                       1. Press the Hold/DND button to put the badge in Do Not Disturb (DND)
                          mode.
                       2. On the main menu of the badge, scroll to display the info icon.
                       3. Use the Select button to display the Info menu.
                       4. Scroll down until RADIO appears, then select it.

                             The badge displays information similar to the following:

 6. Wear the badge normally.
   Use a lanyard or one of the other badge attachments to wear the badge
   properly. Do not handle the badge or read the display as you perform the
   test, or it will not measure access point signal strength correctly.

   Note: You may want to perform a survey with two badges, both in survey
   mode. Wear the first badge normally and listen for beeping tones that
   indicate the general SNR range. Hold the second badge to display the SNR
   value, but turn down the badge volume so the tones do not distract other
   people.
 7. Connect a headset to the badge.
   The badge emits a tone during the test to indicate the communication
   quality. In certain environments, such as hospitals, this tone can be mistaken
   for the emergency sound made by life-support equipment.
 8. Walk slowly through the entire coverage area and listen to the tones made
    by the site survey tool. You must perform the test in two directions offset by
    180 degrees (while facing one direction, and then while facing the direction
    180 degrees opposite).
   Don't forget to include stairways, elevators, kitchens, bathrooms, and other
   areas where Vocera usage exposes gaps in conventional site surveys.
 9. To exit from the Radio Info screen, press the badge Select button.
10. Note any area where the tone from the Radio Info tool indicates that
    the coverage is less than or equal to the acceptable level for the current
    roaming policy, somewhere between 16 and 22.
   You must improve the coverage in these areas in order to have a successful
   deployment.

               6. Note any area where the tone from the CQ tool indicates that the coverage
                  is less than or equal to the acceptable level for the current roaming policy,

                   You must improve the coverage in these areas in order to have a successful
                   deployment.


The Roaming Policy Property
              The Roaming Policy property determines how aggressively the badge attempts
              to roam as the signal-to-noise (SNR) ratio of the transmission from an access
              point deteriorates. The badge assesses the SNR in terms of the SNR metric for
              B2000 badges and the proprietary Communications Quality (CQ) metric for
              B1000A badges, as discussed in Acceptable Voice Quality on page 99.
              The badge begins to look for another access point when the SNR value or CQ
              value drops to a level specified by the Roaming Policy value.
              The Roaming Policy value is an integer from 0 to 3, where 0 specifies the least
              aggressive roaming and 3 is most aggressive. By default, Roaming Policy is set
              to 2. The following table shows the relationship between badge SNR and CQ
              values and Roaming Policy:

                     The previous table shows the typical SNR and CQ values at which the badge
                     initiates roaming. The actual SNR and CQ values may vary somewhat, due to
                     environmental factors and dynamic changes in coverage.
                     If you are not satisfied with the roaming behavior of the badge, you can
                     experiment by adjusting the Roaming Policy property. Make sure you test any
                     changes thoroughly before implementing them on all badges in a production
                     system.

                     To specify the Roaming Policy property:
                     • Use the Badge Properties Editor to set the Roaming Policy property to the
                       appropriate value on all badges.
                        See Setting Advanced Properties on page 55 for more information about
                        how to set the Roaming Policy property.

   Security

              Security is a critical concern for any enterprise application. In particular, the
              data transmitted on a wireless network is often considered to be at risk because
              radio waves can be monitored without physical access to the network.
              Vocera supports well-known industry standards for wireless security. This
              chapter summarizes the security support provided by Vocera and discusses the
              network overhead introduced by various security methodologies.

              Note: You must configure properties in the Vocera badges to support
              the security requirements of your wireless network. See Setting Security
              Properties on page 50 for additional information.


Security Support
              Vocera supports industry standard security systems such as WPA (Wi-Fi
              Protected Access) and WPA2, as well as popular proprietary security methods
              such as Cisco LEAP.
              The following table summarizes the security support in Vocera:

                     The LEAP, PEAP, and EAP-FAST protocols typically require each user in a network
                     environment to be authenticated with a unique set of credentials. However,
                     each badge in a profile must have the same security properties so the Vocera
                     server can automatically update all badges when necessary. Consequently,
                     Vocera supports device authentication for PEAP, LEAP, and EAP-FAST, not user
                     authentication. All badges must present the same set of credentials for network
                     authentication. See About Badge Profiles on page 45.
                     Vocera has tested the following authentication servers:

                     ACS, do not enable EAP-GTC on the server, as this setting will interfere with
                     authentication.




106 ··· Vocera B2000 Badge Guide
                                                                                  WPA Support


WPA Support
              Wi-Fi Protected Access (WPA) is a set of standards and protocols designed to
              make wireless networks secure. WPA was developed by the Wi-Fi Alliance, an
              organization formed to certify interoperability of wireless networking products
              based on the IEEE 802.11 specification. The Wi-Fi Alliance created WPA based
              on Draft 3 of the 802.11i standard.
              The B1000A and the B2000 badge support the following WPA features:
              • WPA-PEAP (Wi-Fi Protected Access Protected Extensible Authentication
                Protocol)
                PEAP is a two-part protocol. In the first part, an authentication server and a
                client set up an encrypted Transport Level Security (TLS) tunnel. The badge
                accepts a certificate from the authentication server, but does not validate it
                because of the processing overhead required.
                In the second part, authentication occurs in the tunnel. PEAP allows you
                to choose among several authentication techniques. Vocera supports the
                MS-CHAP (Microsoft Challenge Handshake Authentication Protocol) version
                2 standard, which provides mutual authentication via user names and
                passwords.
              • EAP-FAST (Extensible Authentication Protocol-Flexible Authentication via
                Secure Tunneling)
                EAP-FAST, like PEAP, is a client-server security architecture that encrypts EAP
                transactions with a TLS tunnel. The tunnel is established based on shared
                secrets called Protected Access Credentials (PACs) instead of public key
                certificates. See Configuring EAP-FAST Authentication on page 112 for
                more information.
                EAP-FAST support is available in the B2000 badge only.
              • WPA-PSK (Wi-Fi Protected Access Pre-Shared Key)
                WPA-PSK (Pre-Shared Key), a technique for verifying identity that is an
                alternative to WPA-PEAP. WPA-PSK offers some of the benefits of TKIP-WPA
                without the overhead of an authentication server. Vocera supports WPA-PSK
                as defined by WPA.
              • TKIP-WPA (Temporal Key Integrity Protocol)
                TKIP-WPA encryption uses dynamic keys that change as the system is used.
              • MIC (Message Integrity Check)
                MIC is a checksum calculated by both the client and the server to confirm
                that the content of a packet has not been changed.

                                                                                   Security ··· 107
  WPA2 Support


WPA2 Support
                     The Wi-Fi Alliance created the WPA2 specification based on the mandatory
                     elements of the 802.11i standard. The WPA2 specification provides greater
                     security than the WPA specification, which is based on a subset of 802.11i.
                     In particular, WPA2 makes use of the hardware-based AES (Advanced
                     Encryption Standard) specification, which is considered superior to the
                     encryption used by WEP and WPA.
                     The B2000 badge supports the following WPA2 features:

                     AES (Advanced Encryption Standard) is a strong form of encryption that is part
                     of the WPA2 standard. The B2000 radio provides hardware support for AES.
                     The hardware of the B1000A badge cannot support this form of encryption.

Cisco Support
                     In addition to their support for industry standards, Cisco also provides
                     proprietary security solutions that have become popular. Vocera supports the
                     following proprietary Cisco security methods:
                     • Cisco LEAP (Lightweight Extensible Authentication Protocol)
                        If your site uses LEAP security, a Vocera badge must submit a user name
                        and password to an authentication server when it accesses your wireless
                        network. The authentication server checks these credentials, and if the user is
                        authenticated, it allows the badge to access the network.
                        The B1000A supports LEAP with WEP and TKIP-Cisco. Cisco no longer
                        supports TKIP-Cisco, so the B2000 badge provides TKIP-WPA as an alternative
                        for customers committed to LEAP.
                     • TKIP-Cisco (Temporal Key Integrity Protocol)

                TKIP-Cisco is Cisco’s proprietary implementation of TKIP. It is available for
                systems that use the LEAP authentication protocol. Cisco refers to this same
                security implementation as Cisco TKIP in Cisco VxWorks and as CKIP in Cisco
                IOS.
                The B1000A supports TKIP-Cisco encryption for LEAP authentication.
                However, Cisco no longer supports TKIP-Cisco, so the B2000 badge provides
                TKIP-WPA as an alternative for customers committed to LEAP.

WEP Support
              WEP (Wired Equivalent Privacy) is the most basic level of security support
              provided for 802.11 networks. B2000 and B1000A badges both support WEP.
              • Open authentication
                Open authentication is an 802.11 standard that allows devices to connect to
                a wireless network without authentication.
              • WEP Wired Equivalent Privacy
                WEP encryption is the basic level of 802.11 security. WEP uses 64-bit or
                128-bit keys (sometimes called 40-bit or 104-bit keys, respectively) to encrypt
                and decrypt data. WEP encryption uses a single key that does not change. If
                Vocera badges and your site’s access points use the same WEP key, they can
                communicate with each other.


Security and Roaming Delays
              In general, increasing levels of security increase the amount of time required for
              a client to associate with the network. The overhead introduced by security can
              cause performance problems with Vocera. This overhead is not noticeable the
              first time a badge associates with an access point, but it may cause a noticeable
              interruption in speech if a badge roams and re-associates while a call is active.
              While encryption techniques such as WEP introduce a certain amount of
              overhead to each packet, the required processing is minimal and does not affect
              Vocera. The overhead introduced by authentication techniques, however, can
              be significant and may affect the performance of the badge as it roams.
              The delay in re-associating when roaming depends upon the specific
              configuration of your network and the type of security you implement. You may
              need to experiment to find the best balance between an appropriate level of
              security and acceptable performance.

Authentication Delays
                     The following table provides general guidelines for the amount of additional
                     overhead different methods of security introduce when roaming. The specific
                     performance you see may vary depending upon the access point you are using
                     and your network configuration.

                     All forms of authentication introduce considerable overhead. In particular,
                     PEAP adds the most overhead due to the time required for connecting to
                     an authentication server. PSK provides a considerable level of security while
                     introducing only minimal overhead.

Optimizing PEAP, LEAP, and EAP-FAST
                     The PEAP, LEAP, and EAP-FAST protocols require back-end authentication servers
                     to authenticate client credentials the first time a client connects to the network,
                     each time the client roams, and at periodic intervals. Various properties control
                     how often the authentication occurs, and in the case of PEAP and EAP-FAST,
                     whether a full authentication or a fast authentication occurs.
                     The authentication that occurs the first time a client connects to the network
                     is not noticeable to a badge user because it appears to be part of the general
                     boot and connection procedure. However, the authentication that occurs
                     during roaming or at a timeout interval can interrupt a conversation, due to

packets that are lost while the authentication server processes credentials and
re-authenticates the badge. You can optimize badge performance by allowing
fast reconnects and setting a lengthy timeout interval, as described in the
following sections.

Timeout Intervals
On authentication servers, a Session Timeout value specifies the duration
of time that elapses before a client such as the badge is required to
re-authenticate, regardless of whether it has roamed. Some vendors may refer
to this timeout value as a group session timeout or a user session timeout.
Because a session timeout always triggers re-authentication, you can optimize
performance by making sure that the timeout interval does not expire too
frequently. For example, if your employees typically work eight-hour shifts,
you could set the session timeout value to eight hours, ensuring that an
authentication timeout does not occur during a shift. For PEAP, a session
timeout will trigger a full authentication, unless fast reconnects are enabled. See
Fast Reconnects on page 111.

Note: Do not confuse this session timeout, with the PEAP session timeout
described in PEAP Session Timeouts on page 112.

Fast Reconnects
PEAP and EAP-FAST require a full authentication the first time a client connects
to the network, but optionally allow a fast reconnect any other time an
authentication occurs, up until the expiration of the PEAP session timeout
interval for PEAP or the expiration of the authorization PAC time to live (TTL)
for EAP-FAST. See PEAP Session Timeouts on page 112 and EAP-FAST
Stateless Session Resume on page 112 for more information about PEAP
session timeout and authorization PAC time to live.
Because a fast reconnect reduces the time required for reauthentication by
several seconds, you can optimize PEAP and EAP-FAST performance by enabling
fast reconnects. For example, if a user roams during a conversation, the
authentication that occurs causes the minimum possible interruption when fast
reconnects are enabled.




                                                                     Security ··· 111
  Configuring EAP-FAST Authentication


                     PEAP Session Timeouts
                     When you are using PEAP authentication, an additional value called the
                     PEAP Session Timeout interacts with fast reconnects. When the PEAP
                     session timeout interval expires, a client is required to perform a full
                     authentication, regardless whether fast reconnects are enabled, the next time
                     any authentication occurs. Do not confuse the PEAP session timeout with the
                     session timeout described in Timeout Intervals on page 111.
                     You can optimize performance by making sure that the PEAP session timeout
                     interval does not expire too frequently, as you do with the regular session
                     timeout. For example, if your employees typically work eight-hour shifts, you
                     could set the PEAP session timeout value to eight hours, ensuring that a full
                     authentication does not occur during a shift.

                     EAP-FAST Stateless Session Resume
                     When you are using EAP-FAST authentication, an additional option called
                     Allow Stateless Session Resume interacts with fast reconnects. This setting
                     is similar to the PEAP Session Timeout setting. Make sure this option is
                     selected, and specify a value for the Authorization PAC Time to Live (TTL)
                     property. The Authorization PAC TTL value (in minutes or hours) sets the
                     time after which the user authorization PAC expires. When ACS receives an
                     expired authorization PAC, the stateless session cannot resume and phase
                     two EAP-FAST authentication is performed. Therefore, you should set the
                     Authorization PAC TTL property to a value that does not trigger a full
                     authentication over the duration of a typical shift.


Configuring EAP-FAST Authentication
                     The EAP-FAST protocol, supported by the B2000 badge, is a client-server
                     security architecture that encrypts EAP transactions with a TLS tunnel.
                     The tunnel is established based on shared secrets called Protected Access
                     Credentials (PACs) instead of public key certificates.
                     To implement EAP-FAST, you must create a PAC on the Cisco ACS and copy it
                     to the Vocera Server. The badge downloads this PAC from the Vocera Server
                     and then exchanges it with an access point that is enabled to support EAP-FAST.
                     EAP-FAST has been tested with Cisco Secure ACS v4.0(1) Build 27.
                     Each badge must use the same user name and password for EAP-FAST
                     authentication (this is also true for LEAP and WPA-PEAP authentication).

                                             Configuring EAP-FAST Authentication


To implement EAP-FAST authentication:
 1. On the Cisco Secure ACS, login and choose System Configuration >
    Global Authentication Setup.
 2. Make sure the Enable Fast Reconnect option is checked.
 3. Click EAP-FAST Configuration.
 4. Make sure the Allow EAP-FAST option is checked.
 5. Enter the following property values:
   • Active Master Key TTL – amount of time that a master key is used to
     generate new PACs.
   • Retired Master Key TTL – amount of time that PACs generated using a
     retired master key are acceptable for EAP-FAST authentication.
   • Tunnel PAC TTL – amount of time that a PAC is used before it expires
     and must be replaced. Set this property value to 5 years to ensure that
     the PAC file you create for Vocera will not expire soon.
 6. Make sure the Allow Stateless Session Resume option is checked, and
    set Authorization PAC TTL to 8 hours, or the length of a typical shift. This
    ensures that a session will not trigger a full authentication over the duration
    of a typical shift.
 7. Click Submit.
 8. On the Cisco Secure ACS, create a single user that all Vocera badges will
    use.
 9. On the computer running Cisco Secure ACS, open an MS DOS command
    prompt window and change to the directory containing the CSUtil file.
10. Start CSUtil with following arguments:
   CSUtil.exe -t -u [username] -passwd [password] -filepath
   C:\ClientPACs
   Where [username] and [password] are the user account and password set
   up for Vocera.
11. Press Enter.
   The CSUtil application creates a PAC called [username].pac in the directory
   C:\ClientPACs.
12. Rename this file to eapfast.pac.
13. Copy eapfast.pac to the following location on both the Vocera Server and
    the stand-alone configuration computer:
   \vocera\config\gen2\badge\res\certificates\EAP-Fast\

                         Using the Badge Properties Editor on page 47.
                     15. In the Badge Type list, choose B2000.
                     16. Click the Security tab, and supply the following property values:
                         • Set Authentication to EAP-FAST.
                         • Set Encryption to either TKIP-WPA or AES-CCMP.
                         • Set User Name to username.
                            Where username is an ACS user ID.
                         • Set Password to password.
                            Where password is the password of the ACS user.
                     17. Click OK to save these values and close the Badge Properties Editor.
                     18. Copy badge.properties to the following location on both the Vocera
                         Server and the stand-alone configuration computer:
                         \vocera\config
                     19. Do either of the following:
                         • Stop the Vocera Server and restart it.
                            This causes the server to reload badge.properties into memory. When
                            the server restarts, it updates the badges with badge.properties and the
                            eapfast.pac file, allowing the badge to be authenticated during boot-up
                            and roaming.
                         • Run the Badge Configuration Utility.
                            When the badge connects, the Badge Configuration Utility updates it
                            with badge.properties and the eapfast.pac file, allowing the badge to
                            be authenticated during boot-up and roaming.

                         Important: The eapfast.pac file must be in place before the badges
                         download the badge.properties file with EAP-FAST security enabled.

THIS BADGE MEETS THE FCC REQUIREMENTS FOR EXPOSURE TO RADIO
FREQUENCY ENERGY (SAR).
Your wireless badge is a radio transmitter and receiver. It is designed and
manufactured not to exceed the emission limits for exposure to radio frequency
(RF) energy set by the Federal Communications Commission of the U.S.
Government. These limits are part of a set of comprehensive guidelines
that establish permitted levels of RF energy for the general population. The
guidelines are based on standards that were developed by independent
scientific organizations through periodic and thorough evaluation of scientific
studies. The standards include a substantial safety margin designed to assure
the safety of all persons, regardless of age and health. The exposure standard
for wireless communications devices employs a unit of measurement known as
the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
Tests for SAR are conducted using standard operating positions, as applicable
to this device, specified by the FCC. The standard incorporates a substantial
margin of safety to give additional protection for the public and to account for
any variations in measurement. Before a badge is available for sale to the public,
sample units must be tested by a certified regulatory lab to verify that they do
not exceed the limit established by the government-adopted requirement for
safe exposure.

                       RF exposure (SAR) tests have been performed on the Vocera badge when it
                       is being worn correctly and used with the approved accessories. The SAR test
                       results show that the badge complies with all FCC exposure requirements.
                       When a properly-oriented badge is operated with the appropriate accessories,
                       as directed in the Vocera User Guide, the level of RF exposure is well below the
                       FCC limit of 1.6W/Kg.
                       Therefore, to ensure compliance with FCC RF exposure guidelines when
                       wearing the Vocera badge, the user should only use Vocera approved
                       accessories (e.g., lanyard, pocket clip, etc.). Accessories that have not been
                       tested for RF exposure compliance with this product may not comply with the
                       FCC RF exposure safety guidelines and should not be used.
                       To ensure RF exposure compliance of the badge when using the lanyard,
                       position and maintain the call button, the speaker, and the antenna facing away
                       from the body, as illustrated in the “Getting Started” section of the Vocera User
                       Guide. The badge and lanyard attachment have been designed specifically to
                       maintain proper orientation during normal usage. Additionally, the lanyard clip
                       can be secured to clothing to provide additional stability. Wearing the Vocera
                       badge with the antenna facing the body may result in non-compliance with
                       FCC RF exposure guidelines and must be avoided.
                       Use only the internal antenna which is part of this product. Any use of
                       unauthorized antennas, any modifications to the supplied antenna, or any use
                       of unauthorized attachments could damage the badge, violate FCC regulations,
                       and void the user’s authority to operate the product.

   Important Safety Instructions

              The Vocera badge (including its battery component) and the Vocera
              battery charger are electronic devices. Care appropriate to the use of
              any electronic device must be taken in using the badge and the battery
              charger in order to minimize the possibility of injury (e.g., from shock)
              and damage (e.g., from fire).
              In addition, the Vocera badge is a wireless communication device
              that works by generating radio frequency (RF) signals. These signals,
              although generally lower in strength than a typical cellular telephone,
              can interfere with other electronic devices that are not appropriately
              shielded against RF signals. If the Vocera badge will be used in
              proximity to sensitive electronic devices for which interference could
              result in serious consequences, you must consult with the manufacturer
              of any such device in order to determine whether the Vocera badge can
              be safely operated in proximity to such device.
              In order to ensure comfortable use of the badge and to avoid possible
              damage to hearing, do not bring the speaker within close proximity of
              the ear while the badge is powered on.
              References below to the “badge” refer to the Vocera badge, including
              its battery component, while references to the “product” refer to the
              badge and the Vocera battery charger.
              In addition to other basic safety precautions appropriate to the use of
              wireless electronic devices, please follow the safety and use instructions
              set forth below.

                       6. Do not position the badge or battery charger near any source of water
                          such as a sink, wash bowl, or toilet. Do not spill liquid of any kind on the
                          product, as doing so may short out parts, causing damage to the product
                          and creating the risk of fire or electric shock.
                       7. Take the badge or charger to a qualified service provider in these
                          circumstances:
                         • If liquid has been spilled onto the badge or charger, or if rain or water has
                           touched the badge or charger.
                         • If the badge or charger does not operate normally after you follow the
                           operating instructions.
                         • If the badge or charger has been dropped or damaged.
                         • If the badge or charger exhibits a distinct degradation in performance.
                         • If the power cord or plug on the charger is damaged or frayed.
                       8. Unplug the charger from the wall outlet before cleaning. To clean or
                          disinfect the badge and charger, wipe with a cloth dampened with
                          germicidal solution or isopropyl alcohol. Use of any other cleaners may
                          damage the badge and void your warranty.
                       9. Use the battery charger indoors only.
                     10. Do not allow anything to rest on the charger‘s power cord. Do not locate
                         the charger where the cord may be damaged or where the cord may cause
                         someone to trip. Keep the power cord away from operating machinery.
                     11. Do not overload outlets or extension cords, because this may cause a fire or

                                                   Additional Instructions Related to Battery Safety


               12. Operate the charger only with a Vocera-approved power adapter.
                  Utilisez le chargeur seulement avec un adaptateur de puissance approuvé
                  par Vocera.


Additional Instructions Related to Battery Safety
                1. Use only the batteries supplied with the product or Vocera-approved
                   replacements.
                2. Do not use the battery to power any device other than a Vocera badge.
                3. Charge the battery only in a Vocera charger and according to the
                   instructions in the Vocera User Guide. These instructions are also included
                   with the charger.
                4. Do not charge the battery in a place where static electricity is generated or
                   let the battery touch any object that is statically charged.
                5. The battery can be stored at temperatures between –4° F and 104° F
                   (between –20° C and 40° C), and can be charged or operated at
                   temperatures between 32° F and 104° F (between 0° C and 40° C).
                6. Do not put the battery into a microwave oven, conventional oven, dryer, or
                   high-pressure container, or dispose of the battery in a fire. If you do so, the
                   battery might explode.
                7. Do not open or puncture the battery or subject the battery to strong
                   physical shock.
                8. Stop using the battery if it exhibits abnormal heat, odor, color, deformation,
                   or is in an abnormal condition.
                9. If you detect leakage or a foul odor, it is especially important to keep the
                   battery away from fire. If battery liquid leaks onto your skin or clothes,
                   immediately wash well with clean water. If liquid leaking from the battery
                   gets into your eyes, do not rub your eyes. Instead, immediately rinse your
                   eyes well with clean water, and consult a doctor.
               10. Handle batteries with care to avoid shorting the battery with conducting
                   materials, such as rings, bracelets, and keys. If the battery shorts, it may
                   overheat and burn you.
               11. After the battery has reached the end of its useful life, we recommend
                   recycling the materials at a recycling center in your community. If you
                   choose to dispose of the batteries, consult the regulations that are in force
                   in your locale.

  Important Information About Use in Certain Areas


                     12. When recycling or discarding the battery, make it non-conductive by
                         applying vinyl tape to the terminals located on the edges of the battery, at
                         the sides.

Important Information About Use in Certain Areas
                       1. Turn your badge OFF in facilities when any posted notices instruct you to
                          turn off all devices that emit a radio frequency. To turn the badge OFF,
                          depress the Hold/DND button for 5 seconds or remove the battery. If the
                          rules of your facility limit use of RF-emitting devices in certain areas, you
                          must familiarize yourself with these rules and follow them strictly.
                       2. If you have any reason to suspect that the badge is interfering with sensitive
                          equipment, turn the badge OFF immediately.
                       3. Turn your badge OFF and do not use the charger when you are in any
                          area with potentially explosive materials in the atmosphere. Sparks in such
                          areas could cause an explosion or fire, resulting in bodily injury or death.
                          Areas with potentially explosive atmospheres include: fueling areas; transfer
                          or storage facilities for fuel or chemicals; facilities with equipment using
                          liquefied petroleum gas, such as propane or butane; and areas where the
                          air contains chemicals or particles, such as grain, dust, or metal powders.
                     FAILURE TO FOLLOW THE FOREGOING INSTRUCTIONS COULD RESULT IN (A)
                     DAMAGE TO EQUIPMENT, VOIDING YOUR WARRANTY AND/OR (B) PROPERTY
                     DAMAGE AND/OR SERIOUS PERSONAL INJURY, INCLUDING DEATH.

                     Make sure the following ports are open for communication:
                     • If a firewall separates the Vocera server machine from the wireless
                       network, you will need to make sure all ports required for badge < > server
                       communication are open. These include 5100 - 5200, and 5400. Also open
                       5300 - 5399 for communications among the badges, the Vocera server
                       machine, and the Telephony server machine (which may or may not be the
                       same as the Vocera server machine).
                     • If access to the User Console or Administration Console is required from
                       outside the firewall, you must also open port 8080 for communication to the
                       Vocera server.
                     • If access to VMI or VAI applications is required from outside the firewall, you
                       must also open ports 5005 and 5251, respectively, for communication to the
                       Vocera server.
