1. Review the "Installation guidelines" on page 12 and "Handling static-sensitive
devices" on page 13.
2. Turn off the computer and all attached devices (see "Turning off the computer"
on page 36); then, disconnect all power cords and external cables.
3. Remove the side cover (see "Removing the side cover" on page 14).
4. Remove the support bracket ("Removing and installing the support bracket" on
page 15).
5. Remove the air baffle by unhooking it from its retaining tabs and lifting it off the
chassis.
6. Locate the second microprocessor socket (connector CPU2) on the system
board.
7. Remove the microprocessor baffle from the second microprocessor socket.
8. If the second microprocessor socket is covered with protective film, peel and
remove the film.
9. Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to
any unpainted metal surface on the computer; then, remove the
microprocessor from the package.
b. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops or clicks in the fully open position
(approximately 135° angle).
Attention: You must ensure that the locking lever on the microprocessor
socket is in the fully open position before you insert the microprocessor in
the socket. Failure to do so might result in permanent damage to the
microprocessor, microprocessor socket, and system board.
