network connectivity and electric power, such as voice over IP (VoIP), 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 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 11 lists the PoE specifications for the SRX550 High Memory Services
Gateway.
