Step 4. Lift the server cover off the server and set it aside.
Attention: For proper cooling and airflow, replace the server cover before you turn on the server.
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.
To replace the server cover, complete the following steps.
Step 1. Position the cover on top of the server.
Step 2. Slide the cover toward the front of the server.
