Description

The VTX079K is a 6U VPX single slot backplane Power Interface Board (PIB) that breaks out the VPX Power connector per VITA 62. Three pin/socket connector style is for the single or three phase input power.  Power studs are used for the output power PO1, PO2, PO3 and +3.3V_AUX. The +/-12V_AUX and VBAT are routed to a connector for the backplanes that may need these auxiliary voltages.

All the ancillary signals such as SM0 thru SM3 (IPMB-A and IPMB-B), Geographic Address (GA), *Enable/*Inhabit, UD0 thru UD6, etc. are routed to connectors to allow the PIB to interface to the backplane and/or external connection.

There are four 4 port toggle switches on PIB. Two set the Geographic address and the *Enable/*Inhabit. The second set allows the remote sense to be connected directly on the PIB vs. connection to the backplane. The PIB has resistors that could be set to increase the Power Module output voltage to take into account the cable voltage loss. These switches allow the reduction of the cables that go between the PIB and the backplane.

The toggle switches could be removed and hardwired based on customer requirement.

The IPMB-A and IPMB-B are routed to three connectors, one for the main backplane and two for optional push/pull fan tray in the system.
