After updating BIOS/firmware with S2600GZ_GL_EFI_BIOS02060005_ME020107328_BMC0127r9958_FRUSDR113.zip, I get a "Power Unit Redund" warning and can't see any "PS1" entries in "Sensor Readings". Both powersupplies have green lights and the system continues running when I unplug one of them.
When rerunning the update I observed this message in the uEFI shell:
Power supply 1 detected but unable to identify model.
Sensors for power supply 1 will not be installed.
When running the command ipmitool fru read 2 fru2.bin and comparing with the good power supply, I see that the first byte is FF instead of 01.
Power Supply 1 FRU (BAD):

- I think the bad FRU is the source of the problem. Is this correct?
- How can I write a correct FRU? I tried to use ipmitool fru write 2 fru2.new.bin, but the memory was write protected.
- Does the BIOS update overwrite the power supply FRU? Was the BIOS update the source of the corruption, or did it just expose the problem?
