NOTE:
Both fan modules must be installed for optimal operation of the
TCX1000-RDM20, if there is only one fan than there will be no redundancy.
Each TCX1000-RDM20 has a fan LED located to the left of the fan.

Airflow Through the Chassis
In the TCX1000-RDM-20 cooling system, cool air enters through the vents in the port
panel and hot air exhausts through the FRU panel. This type of airflow is known as airflow
out or port-to-FRU airflow. When the chassis is installed, it must be positioned so that
the FRUs are next to the hot aisle.
