   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.

   5. Remove the air baffle.

2. Identify and note the location of the faulty DIMM by pressing the Fault Remind button on the motherboard.

   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 must be replaced [1].

   
   
3. To remove the faulty 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 faulty DIMM with another DIMM of the same size and type.

   For DIMM replacement instructions, see Install a DIMM.
