We have a T620 with 2 identical 750watt PSUs as supplied with the server.

Today I have finally managed to do a well overdue Platform/firmware update but have ended up with only 1 functioning PSU.

The front panel LCD shows error:

PSU0006 Power supply 1 is incorrectly configured. Check PSU

The PSU in slot 1 has a flashing orange light

Within the Lifecycle controller firmware update, View Current Versions:

Power Supply.Slot.1 - Version 07.00.00

Power Supply.Slot.2 - Version 07.2B.7D

If I try Launch Firmware Update again I get the message:

Two PSUs of different wattages are installed in the system. They are greyed-out to prevent permanent damage upon simultaneous update. To update the firmware on the PSUs, either individually perform the updates or make sure that both PSUs are of the same wattage.

I am then unable to select either to update. In Launch Firmware Rollback i do not see an option to roll back the PSU firmware.

I saw the message on the 'Select Update Repository' screen warning 'If two PSUs of different wattages are installed, do not perform a simultaneous update' but as they are both 750w I didn't think there would be a problem.

Is there anything I can do to either rollback the PSU firmware or update them individuallly? Will this even help or is the PSU bricked?
