Juniper EX2200 Complete Hardware Guide

Table 9 on page 15 lists the power consumed by each EX2200 switch model. The
maximum power available on a PoE port is 30 W for switches running Junos OS Release
10.3 or later and 15.4 W for switches running Junos OS Release 10.2 or earlier.

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.
