Moving system DIMMs

To move the DIMMs, locate and move them from the impaired controller into the replacement controller and follow the specific sequence of steps.


  1. If you are not already grounded, properly ground yourself.
  2. Locate the DIMMs on your controller module.

    Riser 1 and DIMM bank 1-4
    Riser 2 and DIMM banks 5-8 and 9-12
    Riser 3 and DIMM bank 13-16
  3. 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.
  4. 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.
  5. Locate the slot where you are installing the DIMM.
  6. 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.
  7. Push carefully, but firmly, on the top edge of the DIMM until the ejector tabs snap into place over the notches at the ends of the DIMM.
  8. Repeat these steps for the remaining DIMMs.
