SRX 210 Services Gateway PoE Overview
This section includes the following topics:
Introduction
Power over Ethernet (PoE) is the implementation of the IEEE 802.3 AF standard, allowing both data and electric power to pass over a copper Ethernet LAN cable.
The SRX 210 services gateway provides four PoE ports, which supply electric power over the same ports that are used to connect network devices. PoE ports allow you to plug in devices that require both network connectivity and electric power, such as VOIP phones, wireless access points, and IP phones.
You can configure the gateway to act as power sourcing equipment to supply the power to powered devices connected on the designated ports.
Table 1 lists the SRX 210 services gateway PoE specifications.

PoE Classes and Power Ratings
A powered device is classified based on the maximum power that it draws across all input voltages and operational modes. When Class-based power management mode is configured on the gateway, power is allocated taking into account the maximum power ratings defined for the different classes of devices.
Table 2 lists the classes and their power ratings as specified by the IEEE 802.3 AF standard.
