PoE Overview
PoE provides power to IP telephones over an Ethernet line. The power is transmitted via the
device’s ports to the IP telephones over the same cable carrying IP packets.
The Avaya G250/G350 Device automatically discovers the connection and removal of IP
telephones from the in-line powered ports and provides power accordingly.
The Avaya G250/G350 Device provides power using an internal power supply over a 48 volt
feed.
In addition, you can configure power priorities per port ensuring that important equipment is
guaranteed power whenever necessary.
