Removing a memory board 
1.  Power down the server if the server is not configured for hot-plug RAID 
memory or hot-plug mirrored memory.  
 CAUTION:  Only memory boards with a green Removable LED can 
be removed. Do not attempt to remove any memory board with the 
Removable LED off. 
 CAUTION:  To prevent system failure, do not remove the memory 
board from the server until the board status LED stops flashing. 
2.  Unlock the locking switch, and open the release latch. 
3.  Use the ejector lever to pull the memory board out of the server. 
 
 NOTE:  While the memory board with the failed or degraded DIMM 
is being replaced, the server continues to read and write from the 
operational memory board.
