Introduction
Power over Ethernet (PoE) provides the capability for both data and electric power to
pass over a copper Ethernet LAN cable.
The J-SRX240 Services Gateway supports PoE on all Gigabit Ethernet ports. The PoE
ports transfer electrical power, along with data, to remote devices over standard
twisted-pair cable in an Ethernet network. PoE ports allow you to plug in devices that
require both network connectivity and electric power, such as wireless LAN access points,
and VoIP telephones.
You can configure the services gateway to act as power sourcing equipment for devices
connected on the designated ports.
Table 15 on page 25 lists the J-SRX240 Services Gateway PoE specifications.
