Note
There is a limit to USB 2.0 devices that use less than 2.5 W (less than 0.5 A inclusive of surge current). There
is no support for devices, such as external hard drives, that instantaneously draw more than 0.5 A.
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.
Replaceable Modules
Fans
AC power supplies
HVAC/HVDC power supplies
DC power supplies
The fan and power supply modules are field replaceable and you can replace one fan module or one power
supply module during operations so long as the other 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.
Note
Fans 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 will automatically use 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.
The switch supports the Fabric Extenders (FEXs) listed at
