FIGURE 6 Examples of airflow symbols
The green E symbol indicates an exhaust FRU. This unit pulls air in from the port side of the switch
and exhausts it out the non-port side. This is called front-to-back airflow or forward airflow. This
symbol should appear on FRUs with part numbers ending with -F.
The orange I symbol indicates an intake FRU. This unit pulls air in from the non-port side of the
switch and exhausts it out the port side. This is called back-to-front airflow or reverse airflow. This
symbol should appear on FRUs with part numbers ending with -R.
The show environment fan command will indicate either “forward” or “reverse” airflow.
