Cooling System and Airflow in an EX2200 Switch
The cooling system in an EX2200 switch consists of two fans along the rear of the chassis
that provide side-to-rear chassis cooling. In switch models with network ports in which
PoE is available, there is an additional fan in the power supply.
Figure 8 on page 16 shows the airflow in an EX2200 switch with network ports in which
PoE is not available.
