There are two types of power supplies: a power/cooling module (PCM) and a
peripheral power supply (PPS). Both types of power supplies are hot-pluggable.
This feature allows you to physically remove the failed component from a running
system. A new hot-pluggable component can be inserted into a running system.
Note - The hot-plug feature requires a functioning peripheral power supply to
provide electrical precharge current. Use the
if precharge current is available.
