All of the 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.
