Fan Modules
The Cisco MDS 9396T Multilayer Fabric switch supports two hot-swappable fan modules that allow the
switches to continue to run if a fan module is removed, provided that the preset temperature thresholds have
not been exceeded. You can swap out a fan module without having to bring the system down. Each fan module
on the Cisco MDS 9396T switch has two fans.
The direction of the airflow through a fan module is denoted by colors on the module faceplate:
• Red—Port-side intake airflow (DS-C96S-FAN-I)
• Blue—Port-side exhaust airflow (DS-C96S-FAN-E)
If a chassis has two different fan modules, one supporting port-side exhaust airflow and the other supporting
port-side intake airflow, the switch is immediately powered down.
To verify the current fan module on the switch, use the show inventory fan command.
