module is already installed and operating. 
Perform the following procedure to replace an AT-FAN06 fan module:

The chassis cooling is designed to operate with two fan modules 
operating together. To avoid overheating of the AT-DC2552XS 
chassis, please complete the following procedure within one minute.
1. Loosen the captive screws on the AT-FAN06 fan module.
2. Gently pull the handle of the AT-FAN06 fan module to remove it from 
the chassis.
3. Slowly insert the new AT-FAN06 fan module into the vacant fan slot 
until it is flush with the front of the chassis.
The new AT-FAN06 fan module immediately powers up assuming the 
chassis power supplies are turned on.
4. Tighten the captive screws to fasten the fan module to the chassis.
