necessary, remove the boot media and reseat it into the socket.

Moving the DIMMs
To move the DIMMs, you must follow the directions to locate and move them from the old controller module
into the replacement controller module.
Before you begin
You must have the new controller module ready so that you can move the DIMMs directly from the old
controller module to the corresponding slots in the new one.
Step 1. Locate the DIMMs on your controller module.
Note: Verify that each DIMM is operating properly using the LED states.
Step 2. Note the orientation of the DIMM in the socket so that you can insert the DIMM in the replacement
controller module in the proper orientation.
Step 3. 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.
