Removing the microprocessor and fan sink

To remove the microprocessor and fan sink, complete the following steps:

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

on page 29.

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

32).

5. Remove the lower bezel (see “Removing the two-piece bezel” on page 34).

6. Remove the hard disk drives.

7. Press and hold the drive cage release tab; then, rotate the drive cage out of

the chassis until the retaining tab on top of the cage locks into place.

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

Attention: The fan-sink retention lever is spring-loaded when the fan sink is

in place. Releasing the lever too quickly or allowing it to spring upward can

damage the fan sink and surrounding components.

9. Remove the fan sink from the microprocessor:

a. Disconnect the fan-sink cable from the system board.

b. Release the fan-sink retention lever by pressing down on the end, moving

it to the side and slowly releasing it to the open (up) position.

Important: Be careful when you handle the microprocessor and fan sink.

If the microprocessor and fan sink will be reused, do not contaminate the

thermal material between them.
