Srx300 Series And Srx550 High Memory Services Gateway Interfaces Power And Heat Requirements - Juniper SRX300 Series Reference Manual

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 27 lists the PoE specifications for the SRX550 High Memory Services Gateway.
