Руководство По Установке для Cisco Cisco 5760 Wireless LAN Controller

This section describes how to install a fan module.

The controller has four fan modules. Fan modules are hot-swappable. The controller can operate with 
one fan failure indefinitely, but the faulty fan should be replaced as soon as possible to avoid service 
disruption due to a second fan failure.

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.

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