Cooling System and Airflow in an EX2200 Switch

The cooling system in EX2200 switches, except EX2200-C, the compact, fanless models, consists of two fans along the rear of the chassis that provide side-to-rear chassis cooling. In the PoE models of these switches, there is an additional fan in the power supply.

In the EX2200-C switch the cooling is done by the vents on top and sides of the chassis in non-PoE models and by heatsinks in PoE+ models. Do not block the vents on the chassis. Doing this can lead to overheating of the switch chassis

Under normal operating conditions, the fans operate at a moderate speed to reduce noise. Temperature sensors in the chassis monitor the temperature within the chassis. If any fan fails or if the temperature inside the chassis rises above the threshold, the switch raises an alarm and all functioning fans operate at a higher speed than normal. If the temperature inside the chassis rises above the threshold, the switch shuts down automatically.
