To swap out a fan module when replacing the chassis, you must perform a specific sequence of tasks.
About this task
A video for this task is available at:
- If you are not already grounded, properly ground yourself.
- Remove the bezel (if necessary) with two hands, by grasping the openings on each side of the bezel, and then pulling it toward you until the bezel releases from the four ball studs on the chassis frame.
- Press down the release latch on the fan module cam handle, and then pull the cam handle downward.
The fan module moves a little bit away from the chassis.

- Pull the fan module straight out from the chassis, making sure that you support it with your free hand so that it does not swing out of the chassis.
The fan modules are short. Always support the bottom of the fan module with your free hand so that it does not suddenly drop free from the chassis and injure you.
- Set the fan module aside.
- Repeat the preceding steps for any remaining fan modules.
- Insert the fan module into the replacement chassis by aligning it with the opening, and then sliding it into the chassis.
- Push firmly on the fan module cam handle so that it is seated all the way into the chassis.
The cam handle raises slightly when the fan module is completely seated.
- Swing the cam handle up to its closed position, making sure that the cam handle release latch clicks into the locked position.
- Repeat these steps for the remaining fan modules.
- Align the bezel with the ball studs, and then gently push the bezel onto the ball studs.
