to replicate this problem. It is found that this problem was not replicated on
an RH5885H V3 server configured with four PSUs and only occurred on a server
with two PSUs.
you can configure two or four PSUs on an RH5885H V3 server. When four PSUs are

cannot be scanned on the LCD. If four PSUs are configured but PSU backplanes 1
and 2 still cannot be scanned, check whether the PSU backplanes are abnormal.
If only two PSUs are configured, PSU backplanes 1 and 2 cannot be scanned on
the LCD. This scanning result is normal.
