Removing and Replacing a Hot-Swappable Power Supply
The server can have one or two hot-swappable power supplies. These power supplies are located
at the rear of the server. The supported configuration of the server requires a minimum of one
power supply. You can install or replace a hot-swappable power supply using the procedures in
this section when system power is on or off.
CAUTION: Observe all ESD safety precautions before removing or replacing a power supply.
Failure to follow ESD safety precautions can result in damage to the server.
