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 CN4(pin10-20) for 2170 or CN2 for 2171 and 2172
(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.
