SRX650 Services Gateway Power over Ethernet Overview
Power over Ethernet (PoE) supports the implementation of the IEEE802.3 af and IEE802.3 at standards, which allow both data and electric power to pass over a copper Ethernet LAN cable.
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 1 lists the SRX650 Services Gateway PoE specifications.
