Chapter 3: 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

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.

See Figure 23.
