Prepare the server for component installation:
a) Shut down and remove power from the server as described in
on page
35.
b) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.

Step 2
Remove an existing rear supercap unit:
a) Grasp the two top edges of the air diffuser and lift straight up to free it from the grooves on the chassis mid-brace.
b) Remove the supercap unit from the clip that is on the inside of the air diffuser.
c) Disconnect the supercap cable from the rear RAID controller.
Step 3
Install a new supercap:
a) Set the new supercap unit into the clip on the inside of the air diffuser and push gently until it clicks in place and is
secured.
b) Connect the supercap cable to the rear RAID controller card.
c) Position SAS and supercap cables so that they do not interfere with the diffuser installation. Cables must route out
the rear of the diffuser.
d) Set the air diffuser in place and carefully lower it, using the grooves in the chassis mid-brace as guides. Make sure
that the diffuser alignment flange sits flat on the chassis floor and against PCIe slot 11.

Step 5
Reconnect power cords to all power supplies and then allow the server to boot to standby power mode (indicated when
