Step 2: Remove the fans
To remove the fan modules when replacing the chassis, you must perform a specific sequence of tasks.
Steps
1. 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 ball studs on the chassis frame.
2. Press the orange button on the fan module and pull the fan module straight out of the chassis, making sure
that you support it with your free hand.
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.

connected.
