Your storage system must meet certain criteria depending on your situation:
• It must have the appropriate operating system for the caching module you are installing.
• It must support the caching capacity.
• All other components in the storage system must be functioning properly; if not, you must
contact technical support.
Steps
1. If you are not already grounded, properly ground yourself.
2. Locate the failed caching module near the rear of the controller module and remove it.
a. Press the blue release button and rotate the caching module upward.
b. Gently pull the caching module straight out of the housing.
3. Align the edges of the replacement caching module with the socket in the housing, and then
gently push it into the socket.

If necessary, remove the caching module and reseat it into the socket.
5. Push the blue locking button, rotate the caching module all the way down, and then release the
locking button to lock the caching module in place.
