psutool
The psutool determines which PSUs are in the system, checks the Power Good setting, and reads the eld replaceable unit (FRU)
information. It does not look at the PSU fans and airow direction of the fans.
Tests
The psutool looks for the presence of the PSU and if the PSU is present, it checks the Power Good setting in the CPLD. It does not read
directly from the PSU but reads the CPLD information instead. If the PSU is present and it does not receive a Power Good signal, it does
not know if the power plug is not installed or if the PSU is not operating correctly, so it displays a failure.
