Oracle^® Server X7-2 Service Manual

Identify and Remove a 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 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 should be replaced [1].

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

   For DIMM replacement instructions, see Install a DIMM.
