NOTE: The side of the switch where the network ports are located is the front
of the switch.
Table 15 on page 36 shows the different EX4500 switch models and their direction of
airflow.
In the EX4500 switch models that have front-to-back airflow, the air intake to cool the
chassis is located on the front of the chassis. Air is pulled into the chassis and pushed
toward the fan tray. Hot air exhausts from the rear of the chassis. See
