port information and configuring PoE on a module and port level.
PoE provides power to IP telephones over an Ethernet line using an
Avaya P330 device. The power is transmitted via the device's ports to the
IP telephones over the same cable carrying IP packets.
The Avaya P330 device automatically discovers the connection and
removal of IP telephones from the in-line powered ports and provides
power accordingly.
The Avaya P330 provides the power using an internal 225 watt power
supply over a 48 volt feed. It is possible to attach an external power
supply either for additional power, or as an alternative power supply
should the internal power supply fail.
In addition, you can configure power priorities per port ensuring that
important equipment is guaranteed power whenever necessary.
