Removal and replacement procedures  47 
 
IMPORTANT: Processor socket 1 must be populated at all times or the server does not function. 
 
In a multiprocessor configuration, to optimize system performance, HP recommends balancing the total 
capacity of the DIMMs across the processors. 
To remove the component: 
1.  Power down the server (on page 29). 
2.  Remove all power: 
a.  Disconnect each power cord from the power source. 
b.  Disconnect each power cord from the server. 
3.  Do one of the following: 
o  Extend the server from the rack (on page 30). 
o  Remove the server from the rack (on page 31). 
4.  Remove the access panel ("Access panel" on page 35). 
5.  Remove the heatsink ("Heatsink" on page 44). 
 
 
CAUTION: The pins on the processor socket are very fragile. Any damage to them may require 
replacing the system board. 
 
6.  Open each of the processor locking levers in the order indicated, and then open the processor retaining 
bracket.
