Removing the microprocessor and heat sink

To remove the microprocessor and heat sink, complete the following steps.

1. Read the safety information that begins on page vii and “Installation guidelines”

on page 73.

2. Turn off the server and all attached devices; then, disconnect all power cords

and external cables.

3. Turn the server on its side so that it is lying flat, with the cover facing up.

4. Unlock and remove the side cover (see “Removing the side cover” on page

78).

5. Rotate the power-supply cage assembly out of the chassis:

v Hot-swap models:

a. Remove the hot-swap power-supply. Press down on the orange release

lever and pull the power supply out of the bay, using the handle.

b. Lift up the power-supply cage handle and pull the power-supply cage

assembly all the way up until the retainer latch locks the cage in place

on the chassis.

v Non-hot-swap models, lift up the power-supply cage handle and pull the

power-supply cage assembly all the way up until the retainer latch locks the

cage in place on the chassis.:

6. Remove the microprocessor air baffle by grasping the two tabs and squeezing

them together slightly and lift the baffle out of the server.

7. Rotate the rear system fan air baffle up out of the way by grasping the tab and

pulling the baffle all the way up; then, slide it outward over the rear of the

server until it locks in place.

8. Disconnect any cables that impede access to the heat sink and

microprocessor.

9. Remove the heat sink from the microprocessor:

Attention: The microprocessor release lever is spring-loaded when the

microprocessor is in place. Releasing the lever too quickly or allowing it to

spring upward can damage the microprocessor and surrounding components.

a. Lift the heat-sink locking lever, moving it to the side and slowly releasing it

to the open (up) position.
