Replacing the cover
To replace the server cover, complete the following steps:
1. Align the cover over the server (toward the rear of the server) until the cover
edges slip into position over the chassis.
Important: Before sliding the cover forward, make sure that all the tabs on both
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 hard to remove the cover later.
2. Slide the cover forward toward the front of the server until the cover is
completely closed.
