Replacing a combined FRU in a Brocade VDX 6710-54

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.
