Step 3: Replace or add a caching module
To replace or add a caching module referred to as the M.2 PCIe card on the label on your controller, locate the
slots inside the controller and follow the specific sequence of steps.
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.
1. Locate the caching module at the rear of the controller module and remove it.
a. Press the release tab.
b. Remove the heatsink.
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.
