If you are replacing a server component in the server, you need to turn off the server and peripheral devices,
and disconnect the power cords and all external cables.
To replace the air baffle, complete the following steps.
Step 1. Remove the cover (see "Removing the cover" on page 35).
Step 2. Align the air baffle pins with the baffle pin holes on the server chassis and fan cage assembly; then,
lower the air baffle into the server. Press the air baffle down until it is securely seated.

Step 3. Reinstall the cover (see "Replacing the cover" on page 56).
Step 4. Slide the server into the rack.
If you have replaced a server component or installed an optional device in the server, you need to reconnect
the power cords and all external cables, and turn on the server and peripheral devices.
Attention: For proper cooling and airflow, replace the air baffle before turning on the server. Operating the
server with an air baffle removed might damage server components.

Replacing the cover

Use this information to replace the cover.
Make sure that all cables, adapters, and other server components are installed and seated correctly and
that you have not left loose tools or parts inside the server. Also, make sure that all internal cables are
correctly routed.
Important: Before you slide the cover forward, make sure that all the tabs on the front, rear, and side of
the cover engage the chassis correctly. If all the tabs do not engage the chassis correctly, it will be very
difficult to remove the cover later.
