Figure 41: Cisco Boot-Optimized M.2 RAID Controller, Showing M.2 Drive Installation
Step 6 Install the controller to its socket on the motherboard:
a) Position the controller over socket, with the controller's connector facing down and at the same end as the motherboard
socket. Two alignment pegs must match with two holes on the controller.
b) Gently push down the socket end of the controller so that the two pegs go through the two holes on the controller.
c) Push down on the controller so that the securing clips click over it at both ends.
Step 7 Replace the top cover to the server.
Step 8 Replace the server in the rack, replace cables, and then fully power on the server by pressing the Power button.
Replacing the Supercap (RAID Backup)
This server supports installation of one supercap unit. The unit mounts to a bracket that is in the middle of
the row of cooling fan modules.
The supercap provides approximately three years of backup for the disk write-back cache DRAM in the case
of a sudden power loss by offloading the cache to the NAND flash.
Step 1 Prepare the server for component installation:
a) Shut down and remove power from the server as described in Shutting Down and Removing Power From the Server,
on page 27.
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.
