To allow CMC functionality, the cPCI backplane incorporates a
special connector to carry all the necessary signals to and from
the CMC board. These signals are as follows:
Temperatures
DC rail voltages (+12V, -12V, +5V, +3.3V)
DC main input (dual main inputs)
Battery Power to the CMC (optional)
Fan Tachometers (three blowers)
Fan Health (three groups of fans)
Fan Speed Controls (three groups of fans and three
blowers)
Power Supply status (four power supplies)
