Replacing the Fan Module

Replacing the Fan Module

The three fans in the fan module operate in parallel. If one fan fails, the other two will
continue to operate

However, it is important to replace the fan module immediately.

Replace the fan module at least once every three years.

You will need the following tools:

•

Standard Phillips screwdriver

•

Fan module (A3724-60002)

WARNING

The power cord is the main disconnect for this product. To protect
against hazard, always unplug the AC power cord before removing
the fan module.

1. Relocate or power off devices connected to the hub as needed to prepare for powering

off the hub.

2. Unplug the power cord from the hub.

3. Using a standard Phillips screwdriver, remove the four screws that secure the fan

module. Sheet metal marks indicate the location of the screws on the top and sides of
the hub.
