Chapter 4: Installing the Switch and Modules

Replacing Fan

Module

The AT-FAN06 fan module is hot swappable within the chassis. The 
power to the chassis can remain ON while one of the fan modules is 
replaced. The following procedure assumes a second AT-FAN06 fan 
module is already installed and operating. 

Perform the following procedure to replace an AT-FAN06 fan module:

Warning

The chassis cooling is designed to operate with two fan modules 
operating together. To avoid overheating of the AT-DC2552XS / L3 
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 rear 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. 

See Figure 29 on page 65.
