You can order fans and power supply modules with either port-side intake or port-side exhaust airflow. The power supply modules you order depends on whether you plan to position the ports in a hot or cold aisle.
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.
If the switch has port-side intake airflow (burgundy coloring for fan modules), locate the ports in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), locate the ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut down.
The fan and power supply modules are field replaceable. Replace one fan module or one power supply module during operations, as long as the other installed modules are operating. If you have only one power supply that is installed, install the replacement power supply in the open slot before removing the original power supply.
