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.
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.
7. If you have not already done so, install the bezel.
Step 4: Install the controller modules
After you install the controller modules into the new chassis, you need to boot it to a state
where you can run the diagnostic test.
For HA pairs with two controller modules in the same chassis, the sequence in which you install the controller
module is especially important because it attempts to reboot as soon as you completely seat it in the chassis.
1. Align the end of the controller module with the opening in the chassis, and then gently push the controller
module halfway into the system.
Do not completely insert the controller module in the chassis until instructed to do so.
