Before installing the server cover:
1. Ensure that all adapters and other components are installed and seated correctly and that you have not
left loose tools or parts inside the server.
2. Ensure that all internal cables are correctly routed. See "Internal cable routing" on page 27.
3. If you are installing a new server cover, attach the service label to the inside of the new server cover first
if necessary.
Note: A new server cover comes without a service label attached. If you need a service label, order it
together with the new server cover. The service label is free of charge.
To install the server cover, complete the following steps:

Step 1. Lower the server cover onto the chassis until all tabs on both sides of the server cover engage the
chassis. Then, slide the server cover toward the front of the chassis until the server cover stops and
the front edge of the cover aligns with the edge of the front bezel.
Note: Before you slide the cover forward, ensure that all the tabs 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.
Step 2. Use the key to turn the cover lock to the locked position.
After installing the server cover, reconnect external cables if necessary.
