Chassis Components
Fan Modules
The Cisco MDS 9148T Switch fan modules have a fixed handle for insertion and removal from the chassis.
The Cisco MDS 9148T Switch requires a minimum of two operating fan modules to prevent automatic
shutdown. It supports up to four fan modules. This provides redundancy for uninterrupted operation in the
event of fan module failure. The Cisco MDS 9148T Switch fan modules are hot-swappable to also allow
swapping out of a fan module during operation for uninterrupted operation. During a fan module replacement,
the internal airflow through the chassis is changed. If the internal airflow is disrupted for too long, the preset
temperature thresholds will be exceeded and the system will automatically shut down to prevent permanent
damage.
