Step 1. Read the safety information that begins on page "Safety" on page v and "Installation guidelines" on
page 169.
Step 2. Turn off the server (see "Turning off the server" on page 24) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the
device.
Step 3. Remove the left side cover (see "Removing the left-side cover" on page 193).
Step 4. Disconnect any cables that impede access to the heat sink and microprocessor.
Step 5. Remove the air baffle (see "Removing the air baffle" on page 195).
Step 6. Loosen the screws on the heat sink with a screwdriver by the order as the label showed. If possible,
each screw should be rotated two full rotations at a time.
Step 7. 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.
Step 8. Release the microprocessor retention latch by pressing down on the end, moving it to the side, and
releasing it to the open (up) position.
Step 9. Open the microprocessor bracket frame by lifting up the tab on the top edge. Keep the bracket
frame in the open position.
Step 10. Align the holes on the microprocessor installation tool with the screws on the microprocessor
bracket, then place the microprocessor installation tool down over the microprocessor
handle clockwise
Note: You can pick up or release the microprocessor by twisting the microprocessor installation
tool handle.
