■
Do not replace a PSU backplane unit at the same time as a CPU memory unit. If
you replace a PSU backplane unit at the same time as a CPU memory unit, the
system may fail to operate normally. Replace either the PSU backplane unit or the
CPU memory unit, and
confirm that the newly installed part is normal by using
the showhardconf or showstatus command. Then, replace the other FRU.
