You must order them separately. You can install up to two expansion modules in an EX4550 switch—one in each of the module slots on the front panel and the rear panel of the switch. By installing an expansion module, you add more ports to your switch, thereby increasing the port density of the switch.

Page 57: Cooling System And Airflow
Cooling System and Airflow in an EX4550 Switch on page 35 Cooling System and Airflow in an EX4550 Switch The cooling system in an EX4550 switch consists of three fan modules and a single fan in each power supply. EX4550 switches provide back-to-front airflow (air comes in from the back of the switch) or front-to-back (air exhausts through the back of the switch) airflow depending on the fan modules and power supplies installed in the switch.
Page 58: Airflow Direction In Ex4550 Switches
EX4550 switches except the EX4550-32F-S switches have the fan modules and power supplies preinstalled on the rear panel of the switches. Power supplies and fan modules for the EX4550-32F-S switch are not shipped by default; you must order them separately.
