Identify and Remove a Faulty DIMM

  1. Prepare the server for service.
    1. Power off the server, and disconnect the power cords from the server power supplies.

      See Powering Down the Server.

    2. Extend the server into the maintenance position.

      See Extend the Server to the Maintenance Position.

    3. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.

      See Electrostatic Discharge Safety.

    4. Remove the server top cover.

      See Remove the Server Top Cover.

    5. Swivel the air baffle into the upright position to allow access to DIMMs.
  2. Identify and note the location of the faulty DDR4 DIMM by pressing the Fault Remind button on the motherboard I/O card.

    See Using the Server Fault Remind Button.

    Faulty 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 faulty and should be replaced [1].

  3. To remove the faulty DIMM, do the following:
    1. Rotate both DIMM socket ejectors outward as far as they will go.

      The DIMM is partially ejected from the socket.

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

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

    For DIMM replacement instructions, see Install a DIMM.
