Identify and Remove the Failed DIMM

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

      See Powering Down the Server

   2. Extend the server to 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 Take Antistatic Measures.

   4. Remove the server top cover.

      See Remove the Server Top Cover.

2. Identify and note the location of the failed DDR4 DIMM by pressing the Fault Remind button on the motherboard (see Using the Server Fault Remind Button).

   Failed DDR4 DIMMs are identified with a corresponding amber LED on the motherboard.

   • If the DIMM fault LED is off, the DIMM is operating properly.

   • If the DIMM fault LED is on (amber), then the DIMM has failed and should be replaced.

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

      The DIMM is partially ejected from the socket.

      
      

      Number Description 1 DIMM connector socket 2 DIMM connector key 3 DIMM ejector lever

   2. Carefully lift the DIMM straight up to remove it from the socket.
4. Replace each failed DIMM with either another DIMM of the same rank size (quad rank, dual rank, or single rank) or leave the socket empty.

   For DIMM replacement instructions, see Install a DIMM.
