Installation Guidelines

Observe these guidelines when removing or installing a fan module:

Do not force the fan module into the slot. This can damage the pins on the controller if they are not aligned with the module.

A fan module that is only partially connected can disrupt the system operation.

The controller supports hot swapping of the fan module. You can remove and replace the module without interrupting normal controller operation.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Step 1 Pinch the fan module release handle, and slide the module out.
