Juniper SRX650 Hardware Guide

The SRX650 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 SRX650 Services Gateway reside on the individual XPIMs. The
SRX650 Services Gateway supports the following XPIMs with PoE:
•
16-Port Gigabit Ethernet XPIM
•
24-Port Gigabit Ethernet XPIM
The active 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 SRX650 Services Gateway PoE specifications.
