Removal and replacement procedures  48 
To replace the system board: 
1.  Install the spare system board. 
 
 
 
CAUTION: Failure to completely open the processor locking lever prevents the processor from 
seating during installation, leading to hardware damage. 
 
2.  Open the processor locking lever and the processor socket retaining bracket. Do not remove the 
processor socket cover. 
 
 
 
IMPORTANT: Be sure the processor remains inside the processor installation tool.
