• A fan slot must be open and ready for the new fan module to be installed.
• You must have a new fan module on hand and ready to install within one minute of removing the original
• The new fan module must have the same airflow direction as the other fan and power supply modules
Step 1 Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the
open fan slot in the chassis.
Step 2 Slide the fan module into the fan module bay until it clicks into place and tighten the locking screw.

Removing a Fan Module

The fan module is designed to be removed and replaced while the system is operating without presenting an
electrical hazard or damaging the system.
The Cisco MDS 9000 Series switches have internal temperature sensors that can shut down the system if

the temperature within the chassis exceed certain safety thresholds. To accurately monitor the system
temperature, the temperature sensors require sufficient airflow through the chassis. In the event that a fan
module is removed from the chassis and the airflow is reduced, the system will bypass the temperature
sensor information and shut down after five minutes to prevent undetected overheating. However, the
switches will shut down sooner if the major temperature threshold is exceeded.
