Installing and Removing Fan Modules
This section provides instructions for installing and removing the fan modules for the Cisco MDS 9132T
switch.
You can replace one of the four fan modules at a time while the switch is operating so long as you perform
the replacement within one minute of removal of the old fan module. If you cannot perform the replacement
within one minute, leave the original fan module in the chassis to maintain the designed airflow until you
have the replacement fan module on hand and can perform the replacement.
If you are replacing a module during operations, be sure that the replacement fan module has the correct

direction of airflow, which means that it has the same airflow direction as the other modules in the chassis.
Also, be sure that the airflow direction takes in air from a cold aisle and exhausts to a hot aisle. Otherwise,
the switch can overheat and shutdown.
If you are changing the airflow direction of all the modules in the chassis, you must shutdown the switch
before replacing all the fan and power supply modules with modules using the other airflow direction.
During operations, all of the modules must have the same direction of airflow.
Installing a Fan Module
To install a new fan module, follow these steps:
Before You Begin
