Power Supply Connectors And Voltages - IBM NetVista Hardware Maintenance Manual

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, or use a connection (jumper)
to short the black and green wires of the 20-pin and
4-pin connectors on power supply.
