For testing the Power Supply (w/o systemboard), you must jumper the connector
(J9 or J12) as shown in the following picture.
NOTE: On some power supplies the internal-fan is thermally controlled,
and will run very slow, near w/o any noise indication.
If the power supply protection circuit (current/voltage sensing) shuts down the power supply.
Do the following:
- Check all power supply DC voltages with all external DC cables disconnected.
- Because power-On is normally done via the system board, you must place a jumper
on the appropriate connector to force power on to the power supply. (Necessary because also
this power supply connector is disconnected).
- Now you are ready to perform all the voltage checks according to the connectors shown on
this page. If all voltages are correct, reconnect all connectors one at a time, to find out the root
cause of a shortage or overload.
NOTE: To check for the exact voltages to be within tolerance, measurements must
be taken under load, which means that all power DC-connectors are connected.
