• Be extremely careful, the pins on the socket are fragile. Any damage to the pins may require replacing
the system board.
• Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything.
• Removing the heat sink from the microprocessor destroys the even distribution of the thermal grease and
requires replacing the thermal grease.
• Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants
on the microprocessor contacts, such as oil from your skin, can cause connection failures between
the contacts and the socket.
• Use the microprocessor installation tool that came with the new microprocessor to remove and install the
microprocessor. Failure to use the microprocessor tool may cause damage to the pins on the socket.
Any damage to the pins may require replacing the system board.
To remove a microprocessor and heat sink, complete the following steps:
Step 1. Read the safety information that begins in “Safety” on page v and “Installation guidelines” on
page 36.
Step 2. Turn off the server (see “Turning off the server” on page 26) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the device.
Step 3. Remove the server top cover (see “Removing the server top cover” on page 320).
Step 4. If you have the optional hot-swap rear hard disk drive cage installed, rotate it up (see “Rotating the
optional hot-swap rear hard disk drive cage up” on page 181).
Step 5. Remove the PCI riser-card assembly (see “Removing a PCI riser-card assembly” on page 235).
Step 6. Remove the air baffle (see “Removing the air baffle” on page 322).
Step 7. Disconnect any cables that impede access to the heat sink and microprocessor.
Step 8. If you are removing microprocessor 1, remove the memory module from DIMM connector 6. If
you are removing microprocessor 2, remove the memory module from DIMM connector 12. See
“Removing a memory module” on page 212 for instructions.
Step 9. Loosen the screws on the heat sink with a screwdriver, alternating among the screws until they are
loose. If possible, each screw should be rotated two full rotations at a time.
Step 10. Gently pull the heat sink off the microprocessor. Lift the heat sink out of the server. If the heat sink
sticks to the microprocessor, slightly twist the heat sink back and forth to break the seal. After
removal, place the heat sink on its side on a clean, flat surface.
Note: Removing the heat sink from the microprocessor destroys the even distribution of the
thermal grease and requires replacing the thermal grease.
