The VT894 is a 7U μTCA chassis that provides 12 AMC full size double module slots that can accept any AMC.1, AMC.2, AMC.3 and/or AMC.4. It provides CLK1, CLK2, and CLK3 to each slot. The VT894 has full redundancy. It’s capable of having redundant MCH, Power Modules, as well as redundant Cooling Units (CU) for high availability. The VT892 cooling is from bottom to top. There is an option for redundant/non-redundant clock per μTCA specification. The CLK3 option can be configured for the Fabric clock as well as Telcom clock. There is an option for Port 2 and 3 to be directly connected among the adjacent AMCs or to the fabric B (AMC.3 SATA/SAS switch option on the MCH). The VT894 has a Telco Alarm as well as Redundant FRU information devices and carrier locators. The VT894 has a JSM slot which routes to each JTAG port of the AMC. The VT894 routes ports 12-15 and 17-20 between slots.
