Troubleshooting Server Power Supply -- Dead

[SDib]

OBJECTIVE: LOOKING FOR PINOUT OF HP-R650FF3 POWER SUPPLY

Hello dear experts,

I am working on one of my client's Intel Server which is not switching ON any longer.

These have two redundant power supply, so it would be odd that both would be defective.

In any case, I have repaired many switching power supplies in the past, so I opened them up and did not see any physical evidence of a defective part, especially no bump on top of any capacitor.

The power supply model is: HP-R650FF3

I would like to test each power supply on the oscilloscope, and would need the pinout on these power supplies to be able to switch them ON and test the voltages.

Thank you so much in advance for your support.

I have called Intel and can provide a support ref.# if required.

Best regards

Sam

green LED on either when both plugged in?... if no, i'd look into the PDB or mainboard first instead of testing the PSUs. Try bypassing both PSUs and PDB and use secondary power source directly plugged to board to confirm if power cage has issue.
