Identify and Remove a DIMM

  1. Prepare the server for service.
    1. Power off the server.
    2. Disconnect the power cords from the power supplies.
    3. Extend the server into the maintenance position.
    4. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.
    5. Remove the server top cover.
    6. Remove the air baffle.
  2. Identify and note the location of the failed DIMM by pressing the Fault Remind button on the motherboard.

    See Using the Server Fault Remind Button.

    Failed DIMMs are identified with a corresponding amber LED on the motherboard.

    • If the DIMM Fault LED is off, then the DIMM is operating properly.

    • If the DIMM Fault LED is on (amber), then the DIMM is failed and must be replaced [1].

    Figure showing a failed DIMM.
  3. To remove the failed DIMM, do the following:
    1. Rotate both DIMM slot ejectors outward as far as they go.

      The DIMM is partially ejected from the slot.

    2. Carefully lift the DIMM straight up to remove it from the slot.

  4. Replace each failed DIMM with either another DIMM of the same rank size (quad-rank or dual-rank) or leave the slot empty.
