About this task
To replace the server cover, complete the following steps:
Procedure
1. Make sure that all cables, adapters, and other 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.

3. Slide the cover toward the front of the server.
4. Make sure that the cover correctly engages all the inset tabs on the server.
