Power over Ethernet (PoE) supports the implementation of the IEEE 802.3 af and IEEE
802.3 at standards, which allow both data and electric power to pass over a copper
Ethernet LAN cable.
The SRX550 and SRX650 Services Gateways provide PoE ports, which supply electric
power over the same ports that are used for connecting network devices. PoE ports allow
you to plug in devices that require both network connectivity and electric power, such as
voice over IP (VoIP) and IP phones and wireless access points.
The PoE ports for the SRX550 and SRX650 Services Gateway reside on the individual
XPIMs. The services gateway supports the following XPIMs with PoE:
16-Port Gigabit Ethernet XPIM
24-Port Gigabit Ethernet XPIM
The active Services and Routing Engine manages the overall system PoE power. You can
configure the services gateway to act as power sourcing equipment to supply the power
to the GPIMs connected on the designated PoE ports.
Table 11 on page 16 lists the SRX550 and SRX650 Services Gateway PoE specifications.
