Devices, such as external hard drives, that instantaneously draw more than 0.5 A are not supported.
Note
Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power
supply modules with port-side intake or port-side exhaust airflow. To determine the airflow direction of the
modules installed in your switch, see the following table.

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 modules are installed and 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.
All 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
