Replacing a Software RAID Key Module
To remove and replace a software RAID key module, use the following procedure.
Step 1 Prepare the server for component installation:
a. Power off the server as described in Shutting Down and Powering Off the Server, page 3-7.
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.
c. Remove the top cover as described in Removing and Replacing the Server Top Cover, page 3-8.
Step 2 Remove the software RAID key module:
a. Locate the module on the motherboard (see Figure C-1).
b. Grasp the printed circuit board of the module and lift it from the header.
Note The module must have clearance from the retention clip on the header before the module can
be pulled up. Open the retention clip, then pull up as shown in Figure 3-27.
Step 3 Install a new software RAID key module:
a. Align the module with the pins in the motherboard header.
b. Gently press down on the module until it is seated and the retention clip locks over the module.
