The main power supply connection is obtained using a 24-pin connector. A separate 8-pin connector is used for the +12 V power connector dedicated to providing power to the processor. A third 5-pin auxiliary signal connector is used to communicate with the power supply. The following tables define the pin-outs of these connectors.
