Power Supply Cable Connector Specifications
Refer to the following figures when checking voltages for power supply
connectors and cables.
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 connect pins 2 and 3 on connector J30 (with the switch cable
plug disconnected from the connector on the system board).
