Power Supply Connectors and Voltages

Refer to the following figures when checking for voltages on power supply
cable connectors.
When checking voltages, the power supply fan must be running. To power-on
the power supply without using the on/off switch, use a screwdriver or other
tool to short the connector CN2(pin10-20) for 2158 or CN9 for 2163 (with the
switch cable disconnected from the connector on the system board), or use a
connection (jumper) to short the black and green wires of the 20-pin connector
on power supply.
