To replace a power supply, follow these steps:

Note If you have ordered a server with power supply redundancy (at least two power supplies), you do not have to power off the server to replace a power supply because they are hot pluggable.

Step 1 Remove a power supply or a blanking panel from an empty bay:

a. Do one of the following actions:
