Notes:
• Depending on the model, your server might look slightly different from the illustrations in this topic.
• Use any documentation that comes with the new optical drive and follow those instructions in addition to
the instructions in this topic.
To install the slim optical drive, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface.
3. Remove the server cover. See “Removing the server cover” on page 55.
4. The slim-optical-drive bay is protected with a metal bezel. Remove the two screws that secure the metal
bezel to the chassis. Then, remove the metal bezel from the front of the server. Store the metal bezel in
case you later remove the slim optical drive and need the metal bezel to cover the place.
