Removing a Fan Module on the Cisco MDS 9148S Switch
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 Family has internal temperature sensors that can shut 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 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.
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let
