Safety Information
                 To ensure personal safety and protect the equipment, follow these guidelines:
                 •   Read the safety information in Appendix C, “Translated Safety Warnings.”
                 •   Keep the chassis area clear and dust-free during and after installation.
                 •   Keep tools and chassis components away from walk areas.
                 •   Do not wear loose clothing that could get caught in the chassis.
                 •   Wear safety glasses when working under hazardous conditions.
                 •   Do not perform any action that creates a hazard or makes the equipment unsafe.


                 Warning The ports labeled “1X” through “8X,” “console,” “UP,” and “DOWN” are safety
                 extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV
                 circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits.


                 Warning Unplug the power cord before you work on a system that does not have an on/off
                 switch.

Safety Information




                Warning Do not work on the system or connect or disconnect cables during periods of
                lightning activity.


                Warning Do not touch the power supply when the power cord is connected. For systems
                with a power switch, line voltages are present within the power supply even when the power
                switch is off and the power cord is connected. For systems without a power switch, line
                voltages are present within the power supply when the power cord is connected.


                Warning Read the installation instructions before you connect the system to its power
                source.


                Warning The power supply is designed to work with TN power systems.




                Warning This equipment is intended to be grounded. Ensure that the host is connected to
                earth ground during normal use.


                Warning When installing the unit, the ground connection must always be made first and
                disconnected last.


                Warning Before working on equipment that is connected to power lines, remove jewelry
                (including rings, necklaces, and watches). Metal objects heat up when connected to power
                and ground and can cause serious burns or weld the metal object to the terminals.


                Warning Ultimate disposal of this product should be handled according to all national
                laws and regulations.

          Caution Do not place anything on top of the hub that could block the air flow from the
          vents on top of the hub. Products designed specifically to interoperate with the hub and
          which are stacked on top of the hub with the included stacking clip will not block the air
          flow from the vents.


          Caution To prevent the switch from overheating, do not operate it in an area that exceeds
          the maximum recommended ambient temperature of 113°F (45°C). To prevent airflow
          restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.

Preinstallation
         Before you begin installing the hub:
         •   Assemble the network devices you intend to connect to the hub. These devices must
             support either 10BaseT or 100BaseTX. For example, the Cisco 1548M series Micro
             Switch 10/100 or any of the Cisco 1700 series routers are compatible devices.
         •   Select your cabling:
             — To connect a compatible switch, router, server, PC, or workstation, you must supply
               straight-through Ethernet cables.
                 For information on cabling the hub to a compatible network device, see
                 “Connecting a PC, Workstation, Router, or Server” on page 2-17 or the
                 “Connecting Compatible Hubs and Switches to the Hub” on page 2-19. For more
                 information on straight-through Ethernet cable, see “Straight-Through vs.
                 Crossover Ethernet Cable” on page B-3.
             — To stack up to four Micro Hubs, use the stacking cable included with each hub to
               connect each hub through its UP and DOWN connectors.
                 For information on cabling the hub to another Micro Hub, see “Installing Micro
                 Hubs in a Stack” on page 2-8.
             — To connect a compatible hub or switch in a daisy-chain connection, you must
               supply either a straight-through (for port 5) or crossover Ethernet cable.
                 For information on cabling the hub to a compatible hub or switch, see “Connecting
                 Compatible Hubs and Switches to the Hub” on page 2-19. For more information on
                 straight-through Ethernet cable, see “Straight-Through vs. Crossover Ethernet
                 Cable” on page B-3.

Installing the Hub




Installing the Hub
                 These are the major steps for installing your Micro Hub:
                 1 Verify that the hub is operational by running the power-on self-test (POST).

                                  the next two steps. If you are installing only one hub, skip these steps.



                 2 Install the hubs in a stack.

                 3 Connect the stacking cables to the hubs.

Using POST to Pretest the Hub Operation
          Before installing and cabling the hub, you might want power up the hub and verify that it
          is operational.
          To power up the hub, connect one end of the AC power cord to the AC power connector on
          the hub and the other end of the cord to a power outlet (see Figure 2-6).
          The hub begins the power-on self-test (POST) after power up. POST consists of the nine
          individual tests listed in Table 4-1. The port LEDs show which test the hub is executing. As
          each test executes, a port LED turns green. For example, if the LED for port 4 is green, the
          boot code test (test 1) is being executed. On the hub, the port LED for port 4 turns green
          first, followed by ports 3, 2, 1, 8, 7, and so on. The LED turns off after the test completes.
          The POWER LED is solid amber until POST completes.
          When POST completes, the following conditions can exist (if other devices are not
          connected to the hub):
          •   All POST tests passed—If the POWER LED is green and all of the port LEDs are off,
              no problems were detected. The hub is fully operational.
          •   Nonfatal failure(s) detected—If the POWER LED is amber and the hub is functional,
              POST detected one or more nonfatal failures. Although the hub is still operational and
              can forward packets, it might not operate optimally. Refer to the POST failure message
              displayed on the diagnostic console screen, identifying the nonfatal failure(s) detected
              (as described in the “Understanding POST Results” section on page 4-4).
          •   Fatal failure(s) detected—POST stops when it encounters a fatal failure. If the POWER
              LED is amber and a port LED is blinking green, POST detected a fatal failure. The hub
              is not operational, but the blinking port LED indicates which test failed.
          You should inform your system administrator if one or more nonfatal failures are detected.
          Contact your Cisco representative or reseller for support if any fatal failures are detected.
          The “Understanding POST Results” section on page 4-4 provides additional information,
          including the possible causes of nonfatal and fatal failures.

Installing the Hub




Installing Micro Hubs in a Stack
                     Up to four Micro Hubs can be stacked and connected through the rear panel UP and DOWN
                     ports. Each hub comes with a stacking clip and a screw. Before using the clip, you must
                     assemble the clip and the screw, as shown in Figure 2-2.

                      Caution If the unit you are removing is a managed hub and there is no secondary managed
                      hub in the stack, you lose manageability for the entire hub stack. If the removed managed
                      hub is mounted between two operating units, the Ethernet segment is split into two separate
                      segments when the stacking cables are disconnected.

                      For additional information about repeater types and collision domains, see “Repeater
                      Types” on page A-1. “Ethernet Cable Specifications” on page B-3 provides additional
                      information about Ethernet network guidelines.

Connecting the Stacking Cables
          You can interconnect hubs via the stacking connectors on the rear panel of the hubs. These
          interconnected hubs then appear to the rest of the network and to the management interface
          as a single logical repeater.
          Interconnecting hubs differs from cascaded hubs that are connected via the standard 10/100
          ports on the rear of the hub. The connected hubs then appear to the rest of the network and
          to the management interface as two logical repeaters.


          Note The “Concepts” section on page A-1 provides additional information about repeater
          types, logical repeaters, collision domains, and other helpful concepts.


          Figure 2-5 shows how to attach the stacking cables to a stack of Micro Hubs.

Installing the Hub




Hub Stacking Guidelines
                 Use the following guidelines when connecting the stacking cables:
                 •   Install no more than four Micro Hubs in a stack, even if one or more hubs is powered
                     down.
                 •   No more than two Cisco 1538M managed hubs can be in a stack. The upper
                     management hub is the primary management hub; the lower is the secondary
                     management hub.


                 Note If you have a stack that has two management hubs and you remove one management
                 hub from the stack, it will have the same IP address as the stack. Avoid IP conflict by
                 changing the IP address of the removed management hub before you reuse it and connect
                 it to another hub stack in the network.


                 •   The top hub always has its UP connector open, and the bottom hub always has its
                     DOWN connector open.
                 •   Never connect an UP connector to an UP connector or a DOWN connector to a DOWN
                     connector. UP always connects to DOWN, and DOWN always connects to UP.


                 Note If you incorrectly stack the hubs, no electrical damage occurs; however,
                 management functions might not perform properly, and erroneous management
                 information might be created.


                 •   Align the cable connector pins with the stacking connector holes, and position the cable
                     connector horizontally before slowly inserting it into the stacking connector.

                 Caution Be sure that the cable connector is properly aligned with the stacking connector.
                 Inserting the connector at an angle damages the pins, making the cable unusable.

                                                                            Managing the Hub Stack




Managing the Hub Stack
         You need at least one Micro Hub per three interconnected hubs (one hub stack) if you want
         to manage the stack. A second Micro Hub in the stack can act as a redundant stack manager
         in case the primary manager fails.
         If a hub stack has more than one management hub, the upper management hub in the stack
         is the primary management hub. The lower management hub is the secondary management
         hub.
         To manage the hub stack, you can use the system information (such as the IP, CDP, and
         SNMP information) assigned to the primary management hub. The primary management
         hub also stores the port settings of each hub in the stack. If the primary management hub
         becomes inactive or is disconnected from the stack, the secondary management hub
         becomes the primary management hub and uses the same stack information.

         Note Do not install three or more Cisco 1538M hubs in a stack. No electrical damage
         occurs; however, management functions might not perform properly, and erroneous
         management information might be created.


         •   If a stack has only one management hub and another management hub is added to the
             stack, the system information from the management hub that has the longest system-up
             time is used by the topmost management hub. This happens if the new management hub
             is added either above or below the preexisting management hub.
         •   If you replace the only management hub in the stack with a different management hub,
             the stack will use the settings of the newly installed management hub.


         Caution If you are removing a management hub and there is no secondary management
         hub in the stack, you lose manageability for the entire hub stack. In addition, if the removed
         management hub is mounted between two operating hubs, you split the Ethernet segment
         into two separate segments when the stacking cables are disconnected.


         For information on managing the hub stack through the hub manager, see the “Managing
         the Hub Segments” section on page 3-17.




                                                                        Installation and Startup 2-13
Installing the Hub




Numbering Convention of Hubs in a Stack
                 The physical position of the hubs in the hub stack and the stacking cable connections
                 between hubs determine how they appear to the management interface. The FastHub
                 management interface uses a hub-numbering convention, assigning numbers from top to
                 bottom—the hub at the top of the stack is Group 1, the hub below Group 1 is Group 2, and
                 so on. If you have four hubs in a stack and you remove Group 3 and connect the stacking
                 cable from Group 2 to Group 4, Group 4 is renumbered as Group 3.


Hot Swapping Micro Hubs
                 Micro Hubs can be added to or removed from the hub stack without powering down any
                 hub in the stack. This function is referred to as hot swapping. The stack reconfigures itself
                 in approximately 30 seconds. During this period, all packets received by the hub stack are
                 dropped. However, the end-station protocols retransmit the lost packets; no connections are
                 lost, and there is no degradation in network performance. If a management hub is present,
                 all configured system parameters are retained; however, all network-related statistics are
                 cleared.


                 Caution If you are removing a management hub and there is no secondary management
                 hub in the stack, you lose manageability for the entire hub stack. In addition, if the removed
                 management hub is mounted between two operating hubs, you split the Ethernet segment
                 into two separate segments when the stacking cables are disconnected.


                 Note If you keep a hub interconnected to the stack but only power down that hub, the hubs
                 above and below that powered-down hub will still communicate with each other. However,
                 you will not be able to manage that hub, and it will not be displayed from the hub manager.


                 Note If you have a stack that has two management hubs and you remove one management
                 hub from the stack, it will have the same IP address as the stack. Avoid IP conflict by
                 changing the IP address of the removed management hub before you reuse it and connect
                 it to another hub stack in the network.

          Connect network devices such as PCs, workstations, routers, or servers to the hub ports
          labeled 1 through 8, as shown in Figure 2-8. The network device must have a 10BaseT or
          100BaseTX network interface card (NIC) to connect to the Micro Hub.
          For more information about what kind of Ethernet cable to use, see the “Ethernet Cable
          Specifications” on page B-3.


          Note If you plan to connect a switch or another hub to your Micro Hub, reserve port 5 to
          connect to other hubs and switches without requiring the use of a crossover cable.

                 adapter and follow these steps.




                                                                                Installation and Startup 2-21
Connecting Other Network Devices to the Micro Hubs




               Note The rollover console cable and a RJ-45-to-DB-9 female DTE adapter are supplied
               with the hub. If your management station requires a different adapter—such as a
               RJ-45-to-DB-25 female DTE or RJ-45-to-DB-25 male DCE adapter—you must provide it.


               Step 1     Configure the hub console port settings to match the management station or
                          modem. These are the default settings of the console port:
                          •   9600 baud
                          •   8 data bits
                          •   1 stop bit
                          •   No parity
                          •   No flow control
                          You can change the console port characteristics of the hub from the web-based
                          System Configuration Page (see the “Changing the System Configuration”
                          section on page 3-29) or by using the terminal command from the CLI.


                          Note Make sure the settings of the console port and the management station or
                          the modem match.


               Step 2     Connect one end of the supplied rollover console cable to the console port, as
                          shown in Figure 2-12.


               Caution    Do not connect an actual telephone line, an ISDN line, or an Ethernet cable to
               this console port. Damage to the hub can result. Make sure you use the supplied
               RJ-45-to-RJ-45 rollover cable and adapters to connect the console port to the management
               station or modem.

Step 3     Attach the appropriate adapter, such as the supplied RJ-45-to-DB-9 female DTE
           adapter (labeled Terminal), to a management station or modem.


           Note If you are connecting the hub to a Sun workstation (or to a management
           station with a female DB-25 serial connector), use a male-to-male gender
           changer to attach the supplied RJ-45-to-RJ-45 rollover cable and a
           RJ-45-to-DB-25 female DTE adapter to the management station.




                                                                                                                           Installation and Startup 2-23
Assigning IP Information to a Cisco 1538M Hub




                Step 4      Connect the other end of the supplied rollover cable to the adapter.
                Connector and cabling specifications for the console port are in the Appendix B,
                “Specifications and Cables.”
                Now that the hub is connected to a management station, you can assign IP information to
                the hub (see the “Assigning IP Information to a Cisco 1538M Hub” section on page 2-24).


Assigning IP Information to a Cisco 1538M Hub
                After you install the hub and connect it to a management station, you can assign IP
                information to the hub. IP information identifies the hub to the network and is required to
                manage and monitor the hub through the Cisco 1538 Hub Manager, the CLI, or SNMP.
                You can assign IP information to the hub by either:
                •    Following the hub start-up prompts displayed from a terminal emulation program on
                     your management station. This section provides information on using these start-up
                     prompts.
                or
                •    Using Cisco ConfigMaker if your management station is a PC running
                     Microsoft Windows 95, Windows 98, or Windows NT 4.0. For information about Cisco
                     ConfigMaker, refer to the Cisco ConfigMaker software.
                You should contact your system administrator for the following information:
                •    Hub IP address
                •    Subnet mask (netmask)
                •    Default gateway (router)
                To assign IP information to the hub, follow these steps:
                Step 1      From your management station, start the terminal emulation program.
                            After POST completes, the Continue with configuration dialog? prompt appears
                            on the management station, and you can then follow the prompts to assign IP
                            information to the hub. If the Continue with configuration dialog? prompt does
                            not appear, see the “Troubleshooting” chapter.

Step 2   From the terminal or PC, enter Y:
         Continue with configuration dialog? [yes/no]: Y

Step 3   Enter the IP address (for example: 10.1.105.20):
         Enter IP address: 10.1.105.20

Step 4   Enter the subnet mask (IP netmask) (for example: 255.255.255.0):
         Enter IP netmask: 255.255.255.0

Step 5   Enter the IP address of the default gateway (for example: 10.1.105.254):
         Enter IP default gateway: 10.1.105.254



         Note If the management station from which the Cisco 1538 Hub Manager is
         used is not on the same IP subnet as the hub, you must also assign a default
         gateway (the router for the local subnet).



         The following information is displayed:
         The following configuration command script was created:
         ip address 10.1.105.20 255.255.255.0
         ip default-gateway 10.1.105.254
         !
         end

               Step 6     Enter Y:
                          Use this configuration? [yes/no]: Y

                          The following information is displayed:
                          Building configuration...
                          Use the enabled mode ‘configuration’ command to modify this
                          configuration.

                          Press RETURN to get started.

                          Pressing Return opens a CLI session.
               Step 7     Exit from the terminal session.
               You can now use the hub with its default values or configure and monitor it by using the
               Cisco 1538 Hub Manager, the CLI, or SNMP and the MIB files.



Accessing the Management Interfaces for a Cisco 1538M
               After you assign IP information to the hub, you can access the hub management interfaces.
               This section provides information for accessing the Cisco 1538 Hub Manager, the CLI, and
               SNMP and MIB files.

Accessing the Cisco 1538 Hub Manager
         To access the hub manager, all you need is the IP information of the hub (and the password
         if one has been assigned). IP information for the hub is usually assigned when the hub is
         first started up after installation. (See the “Assigning IP Information to a Cisco 1538M
         Hub” section on page 2-24.)


         Note You can access the hub manager from a PC connected to one of the 10/100 ports.
         Therefore, make sure that you do not disable or otherwise misconfigure the port through
         which you are communicating with the hub. You might want to write down the port number
         to which you are connected. Make changes to the hub IP information with care.


         To access the hub manager, follow these steps:
         Step 1    Start Netscape Communicator (4.03 or higher) or Microsoft Internet Explorer
                   (4.01 or higher).
         Step 2    Ensure that the following browser features are enabled:
                   •    Java
                   •    JavaScript
                   •    Set the caching of pages to Every time in Communicator or
                        Every visit to the page in Internet Explorer.
         Step 3    Enter the IP address of the hub in the Location field if you are using
                   Communicator (the Address field if you are using Internet Explorer) to display
                   the hub manager Home Page (Figure 2-13).

Accessing the CLI
          You can access the CLI
          •   From a console terminal connected to the hub console port. For more information, see
              the “Connecting to the Console Port (Cisco 1538M Hubs)” section on page 2-21.
          •   Through a Telnet session from a remote host by entering the telnet command and the
              name or IP address of the hub.
          •   Through a Telnet session by clicking Telnet on the Home Page.
          When you access the CLI and a password has been defined, the following prompt is
          displayed:
              Cisco Systems Console
              Enter Password:

          Enter the password. The hostname> prompt is displayed after you enter the correct
          password.
          For complete information about the CLI, refer to the Cisco 1538 Series Micro Hub 10/100
          Command Reference.


Accessing the MIB Files through SNMP
          You can access the hub MIB files through SNMP. The following MIB files contain variables
          that can be set or read to provide information about the hub and the traps generated by the
          hub.
          •   RFC1213-MIB.my contains the MIB II (RFC 1213).
          •   ETHERLIKE-MIB.my contains the Ethernet Transmission MIB (RFC 1643).
          •   CISCO-CDP-MIB.my contains the CDP MIB.
          •   SNMP-REPEATER-MIB.my contains the standard MIB for managing the hub.
          •   RMON-MIB.my contains the RFC 1757 RMON (Groups 1, 2, 3, and 9). More
              information about RMON and the RMON groups is provided in the “Remote
              Monitoring” section on page 2-31.
          •   CISCO-SIBU-SIMPLE-UPGRADE-MIB.my contains the MIB module for upgrading

               •   CISCO-SIBU-MANAGERS-MIB.my contains the MIB module for management
                   interfaces on the Cisco 1538M hubs.
               •   CISCO-SIBU-STACKABLE-DUAL-SPEED-HUB-MIB.my contains the MIB module
                   that extends the REPEATER-MIB to manage Cisco low-end stackable repeater
                   products.
               If you are going to manage the hub by using SNMP and the MIB files, the Read and Write
               community strings need to be set. To do this, you can either
               •   Use the default community strings
                   — Read community string. The default is public.
                   — Write community string. The default is private.
               •   Assign community strings by using the SNMP Management Page or by using the
                   snmp-server community command on the CLI.

               Note Wait approximately 30 seconds for the changes to be saved to permanent storage
               before turning off the hub, or the changes might not be saved.


               You can obtain a copy of the MIB files in the following ways:
               •   Using File Transfer Protocol (FTP) to access the ftp.cisco.com server.
               •   Using Cisco Connection Online (CCO) to access the cisco.com server.


Using FTP to Access the MIB Files
               To obtain a MIB file, follow these steps:
               Step 1     Use FTP to access the server ftp.cisco.com.
               Step 2     Log in with the username anonymous.
               Step 3     Enter your e-mail name when prompted for the password.
               Step 4     At the ftp> prompt, change directories to /pub/MIBs.
               Step 5     Use the get README command to display the readme file listing available
                          files.
               Step 6     Use the get MIB_filename command to get a copy of the MIB file.

Remote Monitoring
             The Remote Monitoring (RMON) MIB is used by network managers to monitor remote
             devices. An RMON implementation consists of a software probe that continually collects
             statistics about a LAN and a management station that communicates with the probe. The
             probe transfers information to the management station on request or when a predefined
             threshold is crossed.
             The hub supports four RMON groups (Table 2-1) as defined in RFC 1757. Default statistic
             rows are created for each port when you start the hub. You can obtain information about the
             four supported groups by using any SNMP management application.




                                                                          Installation and Startup 2-31

               Table 2-1        RMON Groups and Their Functions

               Group Name       Description
               Statistics       This group collects traffic and error statistics for a specific interface. For
                                example, you could use this group to determine how many error packets have
                                been seen on a given port.
                                Statistics from this group can be used by the history group to record historical
                                views of network performance. A statistics row is established by default for
                                each hub port.
               History          This group periodically samples the counters generated by the statistics group.
                                This information can be used to establish baseline information regarding
                                network activity. You can define the intervals you want to record information
                                for, and you can define how many of the samples are to be stored.
                                Note RMON statistics gathering has a maximum limit of 50 history buckets
                                per historyControlTable entry.
               Alarm            This group generates alarms according to user-defined thresholds. You could,
                                for example, configure RMON to generate an alarm when alignment errors on
                                a port exceeded a predefined limit. Rising and falling thresholds can be
                                defined, and the events group can generate traps and automated responses
                                based on the alarms.
               Event             This group sends traps to the management station based on information
                                (alarms) received from the alarm group.



Where to Go Next
               Now that you have installed the hub and, if you have a managed hub, assigned IP
               information to the hub, continue to Chapter 3, “Configuring and Monitoring from the Hub
               Manager,” for configuration and monitoring information.
