Step 2: Move the fans
To move the fan modules to the replacement chassis when replacing the chassis, you must perform a specific
sequence of tasks.
Steps
1. If you are not already grounded, properly ground yourself.
2. 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.
3. Press down the release latch on the fan module cam handle, and then rotate the cam handle downward.
The fan module moves a little bit away from the chassis.
4. 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.
5. Set the fan module aside.
6. Repeat the preceding steps for any remaining fan modules.
7. Insert the fan module into the replacement chassis by aligning it with the opening, and then sliding it into
the chassis.
8. 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.
9. Swing the cam handle up to its closed position, making sure that the cam handle release latch clicks into
the locked position.
The fan LED should be green after the fan is seated and has spun up to operational speed.
10. Repeat these steps for the remaining fan modules.
Step 3: Replace a chassis from within the equipment rack or system cabinet
You must remove the existing chassis from the equipment rack or system cabinet before you can install the
replacement chassis.
Steps
1. Remove the screws from the chassis mount points.
2. With two people, slide the old chassis off the rack rails in a system cabinet or equipment rack, and then set
it aside.
3. If you are not already grounded, properly ground yourself.
4. Using two people, install the replacement chassis into the equipment rack or system cabinet by guiding the
chassis onto the rack rails in a system cabinet or equipment rack.
5. Slide the chassis all the way into the equipment rack or system cabinet.
6. Secure the front of the chassis to the equipment rack or system cabinet, using the screws you removed
from the old chassis.
