Caution -
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 a PSU backplane unit or CPU memory
unit, and confirm that the newly installed part is normal by using the showhardconf
or showstatus command. Then, replace the other Field Replaceable Unit (FRU).
