The SRX550 High Memory Services Gateway provides 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
Voice over IP (VoIP) and IP phones and wireless access points.
The PoE ports for the SRX550 High Memory Services Gateway reside on the individual
XPIMs. The SRX550 High Memory Services Gateway supports the 16-Port Gigabit Ethernet
XPIM with PoE.
The Services and Routing Engine (SRE) 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 4 on page 9 lists the SRX550 High Memory Services Gateway PoE specifications.
