M4U-19A
Primary construction is from high strength .060 5052 aluminum alloy. The front panel is milled from a single piece of .250 inch aluminum. A door covers the drives and air inlet. The front panel provides an embedded EMI/ environmental gasket and multiple captive fasteners on the door to secure the system from contamination. The lid is secured with a number of captive screws and is provided with an EMI/ environmental gasket. The overall effect is a very robust enclosure to protect the system in any foreseeable environmental environment. Cooling is provided by two 92mm hot swap fans providing 120CFM each of high pressure air flow. The front door is provided with an easily serviced air filter with various classes available. A chassis over- temperature alarm and fan failure circuit monitors chassis conditions. The system is provided with two removable drive bays for 3-1/2 inch SCSI, SATA or EIDE drives. Two slim DVD/RW drives can be mounted. Provision for enterprise class 2-1/2 inch drives in a RAID configuration can be made. System controls are mounted behind the front door and include power control, system reset, and alarm reset. Mounted in the front panel is the Power-on LED, Fan Failure and Overtemp LEDs. The internal controls are mounted on an easily accessible PCB and overlay providing for simple customization. The M4U-19A is optimized for installation of a passive backplane and Single Board Computer. This configuration fits the mission requirements for quick access to boards for system repair and upgrade. A wide variety of active backplanes provides PICMG 1.0 and 1.3 compatibility for virtually any slot mix required by the plug-in cards including PCI-Express X1 through X16, PCI-X, PCI and even ISA. A hold-down bar provides for securing the cards for any adverse shock and vibration environment. A Delrin block secures the front of the SBC providing enhanced security for the heavy heat sinks on the SBC. An optional configuration allows for mounting an ATX motherboard when advantageous to the mission. A standard 4U PS/2 style power supply can be mounted including redundant supplies and DC input. A Mil Std 704 or 1275 compliant supply is available for military airborne or ground installations. The chassis provides a rear mounted ground stud and low smoke / zero halogen wiring is available for military compliance. All fasteners are either self locking or are secured with Loc-Tite during assembly. Please Note: The M4U-19A is a semicustom COTS Plus solution. System are tailored exactly to customer requirements and environmental demands. Chassis Plans offers turn-key configured systems exactly built to customer specification and requirements.
