Installing a CPU
NOTE: HP recommends that you do not swap processors (CPUs) from one system board to another.
To install a CPU:
1. Power down the workstation (see
Predisassembly procedures on page 69).
2. Disconnect power from the workstation (see
Predisassembly procedures on page 69).
3. Remove the side access panel (see
Removing the side access panel on page 72).
4. If your system has an airflow guide, remove it (see
Removing the airflow guide on page 92).
5. Remove the CPU heatsink (see
Removing the CPU heatsink on page 127).
6. Remove the CPU (see
Removing a CPU on page 130).
7. 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.
8. 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.
