To replace the ThinkServer RAID Super Capacitor Module, do the following:
1. Remove all external 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. If
the server is in tower form factor, lay the server on its side for easier operation.
3. Remove the server cover. See "Removing the server cover" on page 72.
4. Disconnect the cable from the ThinkServer RAID Super Capacitor Module. Remove the screw that
secures the ThinkServer RAID Super Capacitor Module and then disengage it from the chassis.
