VTX985

The VTX985 is a dual slot 3U VPX chassis conduction cooled for two 3U VPX modules. The chassis can accept a front and a Rear Transition Module (RTM).

The Chassis CPU will monitor and maintain the VPX module wedge temperature, set by the user. This allows testing of the conduction cooled modules without going through the thermal chamber.

The chassis has provision to mount to a 19” Rackmount.

Power Supply

The VTX985 Universal AC power supply provides 400W to the chassis. The chassis supplies all the necessary power (+12V, -12V, +5V, +3.3V etc.) to the module in accordance with VITA 46 specifications.

A battery pack is included that provides VBAT to the module. The chassis provides the current draw on the +12V, +5V and +3.3V by the VPX module and its associated RTM. 

Cooling

Variable speed fans controlled by the onboard CPU keeps the wedge at the user defined temp.

Backplane

The backplane provides all the necessary VITA 46 signals set by the user (NVMRO, SYSRESET, SYS_CON, driver the dual clock, etc.). All the connectors are installed P0 thru P6 and are routed from the front to the rear. The backplane can be ordered with custom routing between the two modules. The default routing, routes all P1 ports between the two modules.

Health Monitoring

The chassis comes with the VadaTech 4th Generation shelf manager (VT040) that monitors the VPX board sensors in compliance to VITA 46.11. The VT040 supports Tier 2 Health Management and comes with the VTX985 chassis. For a more complete and detail description of the VT040, the data sheet may be downloaded from VadaTech web page.

JTAG

The backplane breaks-out the JTAG signals via a header connector to enable external connection of a JTAG probe.
