Moving the DIMMs

To move the DIMMs, you must follow the directions to locate and move them from the old controller module into the replacement controller module.

Before you begin

You must have the new controller module ready so that you can move the DIMMs directly from the impaired controller module to the corresponding slots in the replacement controller module.


  1. Locate the DIMMs on your controller module.
  2. Note the orientation of the DIMM in the socket so that you can insert the DIMM in the replacement controller module in the proper orientation.
  3. Eject the DIMM from its slot by slowly pushing apart the two DIMM ejector tabs on either side of the DIMM, and then slide the DIMM out of the slot.
    Attention: Carefully hold the DIMM by the edges to avoid pressure on the components on the DIMM circuit board.
    The number and placement of system DIMMs depends on the model of your system.

    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.
    Attention: 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.
