The fan and power supply modules are field replaceable. You can replace one fan module or one power supply
module during operations, so long as the other installed modules are operating. If you have only one power
supply that is installed, you can install the replacement power supply in the open slot before removing the
original power supply.
Fan and power supply modules must have the same direction of airflow. Otherwise, the switch can overheat
and shut down. If you are installing a dual-direction power supply, that module automatically uses the same
airflow direction as the other modules in the switch.
Note
If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports in
the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must locate the
ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.
Caution
The switch supports the Fabric Extenders (FEXs) listed at https://www.cisco.com/c/dam/en/us/td/docs/switches/
datacenter/nexus9000/hw/interoperability/fexmatrix/fextables.html.
