The VT891 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 VT891 has full redundancy. It’s capable of having redundant MCH, Power Modules, as well as redundant Cooling Units (CU) for high availability. 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 VT891 has a Telco Alarm as well as Redundant FRU information devices and carrier locators. The VT891 has a JSM slot which routes to each JTAG port of the AMC.

The VT881 is a 2U μTCA chassis that provides four AMC full size and eight mid size that can accept any AMC.1, AMC.2, AMC.3 and/or AMC.4. It provides CLK1, CLK2, and CLK3 to each slot in addition to the JTAG signals. The VT881 has full redundancy. It’s capable of having redundant MCH, Power Modules, as well as redundant Cooling Units for high availability Option for redundant/non-redundant clock per μTCA specification. The CLK3 option can be configured for the Fabric clock as well as Telcom clock.The chassis has a JTAG Switch Module (JSM) slot per μTCA specification. This provides transparent communication between the front JTAG port and the selected AMC device .The VT881 has a Telco Alarm as well as Redundant FRU information devices and carrier locator.
