To see the components that you use when installing a power supply unit, see
for the AC power supply with port-side exhaust airflow,
supply with port-side intake airflow, and
port-side exhaust airflow.
You can order the Cisco Nexus 2224TP FEX with AC power supplies that have port-side exhaust or
port-side intake airflow for cooling or DC power supplies that have port-side exhaust airflow. The
port-side intake airflow components have a black stripe on their fan side surface for easy visual
identification. The port-side exhaust airflow components do not have a black stripe.
Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow
direction and that the air intake for those modules is positioned on a cool aisle. If you install a module
that uses a different direction of airflow from the other modules in your system, you will see an error
message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can
over heat and shut down.
If one power supply is installed in the chassis, but the other power supply slot is empty, you should use
a blank filler panel to cover the empty slot.
