The SRX210 Services Gateway supports PoE on four 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 VoIP and IP phones and wireless access points.
The PoE+ functionality is available from Junos OS Release 10.2 or later.
The PoE+ functionality is available only if your gateway is using 54V power supply. You can order the 54V power supply from Juniper Networks. Contact your Juniper Networks customer service representative for more information.
