Removing and Installing the Fan Module

The fan module is designed to be removed and replaced while the system is operating without presenting

an electrical hazard or damage to the system, provided the replacement is performed promptly.

This section provides the following information:

•

You will need a flat-blade or number 2 Phillips screwdriver to perform these procedures.

The Cisco MDS 9000 Family switches have internal temperature sensors that are capable of shutting

Caution

down the system if the temperature at different points within the chassis exceed certain safety thresholds.

To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan

module is removed from the chassis, the Cisco MDS 9000 Family switches will be shut down after five

minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if

the higher-level temperature threshold is exceeded.
