EX4500 Switch Models
The EX4500 switch is available in eight models. Table 1 lists the models for an EX4500 switch, the airflow direction of the switch, the components included in each model, and the Junos OS Release in which they were introduced.
 | Note: The side of the switch where the network ports are located is the front of the switch. |
