How to Remove a DIMM

An animation of the procedure to remove a DIMM is available. See animation showing DIMM removal.

Before You Begin

  1. Prepare the server for service. See How to Prepare for Service.
  2. Remove the CMOD from the server. See How to Remove a CPU Module (CMOD).
  3. Set the module on a flat antistatic surface with ample surrounding space and light.
  4. Remove the CMOD cover. See How to Remove the CPU Module (CMOD) Cover.
  5. To identify DIMM failure, press the Fault Remind button on the CMOD motherboard.

    The Fault Remind button activates the LEDs for the DIMM pairs that contain faulty DIMMs.

    Note - For more DIMM troubleshooting information, refer to Sun Server X2-8 (formerly Sun Fire X4800 M2) Diagnostics Guide.

  6. To unlock the DIMM, simultaneously rotate the two release levers outward fully away from the DIMM.

    This action unlocks and ejects the DIMM from the DIMM slot.
