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
reach an overtemperature state 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 (N2200-P-BLNK) to cover the empty slot.
