Notes:
• To maintain the EMI integrity and cooling of the server, install a new hot-swap redundant power supply
as soon as you remove the failing one or cover the other bay with a protective shield if you just use
one power supply to provide power.
• Your hot-swap redundant power supply might look slightly different from the illustrations in this topic.
• Use any documentation that comes with the new hot-swap redundant power supply and follow those
instructions in addition to the instructions in this topic.
To install or replace a hot-swap redundant power supply, do the following:
1. Do one of the following:
• If you are installing a hot-swap redundant power supply, locate the bay for the power supply in the
rear of your server. Insert two fingers into the two holes in the protective shield that covers the bay,
and then pull the shield out of the chassis. Store the shield in case that you later remove the power
supply and need the shield to cover the bay.
