Notes:
• Depending on the model, your server might look slightly different from the illustrations in this topic.
• If you remove the IDM, the server will lose the diagnostic LEDs on the IDM panel.
To replace the IDM, 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. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See “Removing the server cover” on page 69.
4. Locate the IDM. See “Server components” on page 25.
5. Disconnect the cable from the rear of the IDM.
6. Remove the two screws that secure the IDM and then carefully remove the IDM from the chassis.
