Replaceable Modules
AC power supplies
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 installed, you can install the replacement power supply in the open slot before removing the
original power supply.
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.
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.
