Replace a Fan Module
The Cisco 8501 switch uses eight fan modules but it can operate with seven fan modules while you replace
one. When you remove one fan module, the other fan modules speed up their fans to maintain the designed
airflow.
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. Please keep the replacement fan modules ready prior to attempting
this task.
To ensure adequate airflow and prevent overheating, do not operate the switch with four fan modules for more
than 10 minutes.
