Installing a CPU
NOTE: HP recommends that you do not swap processors (CPUs) from one system board to another.
To install a CPU:
1. Disconnect power from the workstation (see
Predisassembly procedures on page 62).
2. Remove the side access panel (see
Removing the side access panel on page 65).
3. Remove the CPU heatsink (see
Removing the CPU heatsink on page 98).
4. Remove the CPU (see
Removing a CPU on page 101).
5. Using extreme care, fully raise the CPU socket lever and cover.
CAUTION: The CPU socket contacts are delicate. To avoid bending the contacts, use extreme
care when installing the CPU in the socket.
6. Align the notches in the CPU base with the tabs on the socket as shown in the figure below.
Seat the CPU into the socket. Ensure that the underside of the CPU is level with the top of the CPU
socket.

7. The CPU cover plate has two tangs opposite its hinge. The tangs slip beneath the mounting screw
on the systemboard as the CPU cover plate hinges downward over the CPU. Close the CPU cover
plate by closing the socket lever, latching the lever securely into the locking notch on the cover
plate.
8. Replace the CPU heatsink (see
Installing the CPU heatsink on page 99), and then close the side
access cover.
