The storage system comes with two slots available for the caching module and only one slot is
occupied, by default.
2. If you are adding a caching module, go to the next step; if you are replacing the caching module, gently
pull it straight out of the housing.
3. Align the edges of the caching module with the socket in the housing, and then gently push it into the
socket.
4. Verify that the caching module is seated squarely and completely in the socket.
If necessary, remove the caching module and reseat it into the socket.
5. Reseat and push the heatsink down to engage the locking button on the caching module housing.
6. Repeat the steps if you have a second caching module. Close the controller module cover, as needed.
Step 4: Reinstall the controller
After you replace a component within the controller module, you must reinstall the controller module in the
system chassis and boot it to a state where you can run diagnostic tests on the replaced component.
1. Align the end of the controller module with the opening in the chassis, and then gently push the controller
module halfway into the system.
