EX4550, Fantray PSU-Side Airflow Intake (Spare)

Part Number: EX4550-FANMODULE-AFI

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.

You remove and replace a fan module from the rear panel of the chassis. The switch continues to operate for a limited period of time (30 seconds) during the replacement of the fan module without thermal shutdown.
