contaminate it. This damages its heat-conducting capability and exposes the new
microprocessor to overheating.
1. Read the safety information that begins on page v and "Installation guidelines"
on page 21.
2. Turn off the server and all attached peripheral devices. Disconnect all power
cords; then, disconnect all external signal cables from the server.
3. Remove the server from the rack; then, remove the server cover (see
"Removing the cover" on page 23).
4. Remove the air baffle for microprocessor 2 (see "Removing an air baffle" on
page 24).
5. Locate the microprocessor 2 socket (identifier CPU2) on the system board.
