IOX Control Panel Display (CPA)

The CPA mounts on the front of the XUC. The CPA contains one XFPB (IOX Front Panel Board) and an

attached 48V power on/off switch cable assembly. It provides a 1-1/2 digit cabinet number display (decimal),

and LEDs for +5.3V Housekeeping Good and +48V Good. These are directly visible over a wide angle from the

front of the IOX. The XFPB also has an ambient temperature sensor.

Each IOX cabinet contains a Rear Panel Display (RDM) module. The RDM contains two, one-inch,

seven-segment green displays for the cabinet number and two green “power good” LEDs for +5V

housekeeping and +48V.
