Cooling System and Airflow in an EX2200 Switch on page 19
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
