Moving a caching module, if present

If your system has a caching module, you need to move the caching module from the old controller module to the replacement controller module. The caching module is referred to as the M.2 PCIe card on the controller module label.

Before you begin

You must have the new controller module ready so that you can move the caching module directly from the old controller module to the corresponding slot in the new one. All other components in the storage system must be functioning properly; if not, you must contact technical support.

About this task

A video for this task is available at:
  1. Locate the caching module at the rear of the controller module and remove it.
    1. Press the release tab.
    2. Remove the heatsink.


  2. Gently pull the caching module straight out of the housing.
  3. Insert the new caching module in the controller, and then align the edges of the caching module with the socket housing and 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. Close the controller module cover, as needed.
