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. For port-side intake airflow, the fan and
AC power supply modules have burgundy coloring. For port-side exhaust airflow, the fan and AC power
supplies have blue coloring. You can also order the 1200-W HVAC/HVDC power supply which has
dual-direction airflow with white coloring. Dual-direction airflow modules automatically use the airflow
direction of the other modules installed in the switch.
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.
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.
