You can order the Cisco Nexus 2300 Series platform with AC power supplies that have port-side exhaust
or port-side intake airflow for cooling or DC power supplies that offer port-side exhaust and port-side
intake airflow. The port-side intake airflow components have a black stripe on their front surface for easy
visual identification. The port-side exhaust airflow components do not have a black stripe.
Note Colored handles on each power supply clearly indicate the airflow direction.
Be sure that all of the power supply and fan modules in the same chassis have the same airflow direction
Caution
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 than the other modules in the same switch, the switch can overheat and shut
down. 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 (part number N2200-P-BLNK) to cover the empty slot.
