Both forward (port-side exhaust) and reversed (port-side intake) airflow schemes are supported. The
port-side exhaust scheme is used when the cold air flows in through the side having the fans (facing the
cold aisle) and exhausts out of the side having the ports (facing the hot aisle). Port-side intake scheme
is used when the air flows in through the ports (facing the cold aisle) and leaves through the side having
the fans (facing the hot aisle).

direction of airflow that is used with the switch.
Caution
The switch must run with all of its power supply and fan tray modules taking in air from a cold aisle and
exhausting air to the hot aisle. If they take in air from a hot aisle, an overtemperature condition can occur
and the switch will shut down. If the airflow directions are mixed in the same switch, you will see an
error.
