Overview
Overview
Note All 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.
Caution 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.
