Step 3. If the NVMEM LED is not flashing, there is no content in the NVMEM; you can skip the following
steps and proceed to the next task in this procedure.
Step 4. If the NVMEM LED is flashing, there is data in the NVMEM and you must disconnect the battery to
clear the memory:
a. Locate the battery, press the clip on the face of the battery plug to release the lock clip from

Step 5. Return to step 2 of this procedure to recheck the NVMEM LED.
Step 6. Locate the DIMMs on your controller module.
Note: Verify that each DIMM is operating properly using the LED states.
Step 7. Note the orientation of the DIMM in the socket so that you can insert the replacement DIMM in the
proper orientation.
Step 8. Eject the DIMM from its slot by slowly pushing apart the two DIMM ejector tabs on either side of the
DIMM, and then slide the DIMM out of the slot.
Attention: Carefully hold the DIMM by the edges to avoid pressure on the components on the
DIMM circuit board.
The following illustration shows the location of system DIMMs:
