The following illustration shows the location of system DIMMs:
4. Repeat these steps to remove additional DIMMs as needed.
5. Verify that the NVMEM battery is not plugged into the new controller module.
6. Locate the slot where you are installing the DIMM.
7. Make sure that the DIMM ejector tabs on the connector are in the open position, and then insert the DIMM
squarely into the slot.
The DIMM fits tightly in the slot, but should go in easily. If not, realign the DIMM with the slot and reinsert it.
Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the slot.
8. Repeat these steps for the remaining DIMMs.
9. Locate the NVMEM battery plug socket, and then squeeze the clip on the face of the battery cable plug to
insert it into the socket.
Make sure that the plug locks down onto the controller module.
Step 5: Move a caching module, if present
If your AFF A220 or FAS2700 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.
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.
1. Locate the caching module at the rear of the controller module and remove it.
