Physical Media; Power Over Ethernet (Poe) - Avaya G250 Overview

Summary of services

Physical media

The G350 provides LAN services through the following Ethernet ports for the connection of local
data devices:
Switched LAN ports. Configurable switched Ethernet ports on the MM314 media module
●
(see MM314 LAN media module
LAN media module
which automatically detects and corrects the polarity of crossed cables. This results in
simplified LAN installation and maintenance.
Fixed LAN port. The fixed LAN port on the chassis, connected to the internal LAN switch.
●
The fixed LAN port supports HP auto-MDIX, which automatically detects and corrects the
polarity of crossed cables. This results in simplified LAN installation and maintenance.
The G250 provides LAN services through eight fixed ETH LAN PoE ports on the chassis.
Note:
The G250-DCP only has two fixed ETH LAN ports. These ports do not support
Note:
PoE.

Power over Ethernet (PoE)

In the G350, the MM314 and MM316 media modules' ports provide power to data devices over
the Ethernet connection (PoE). The ports support the connection of IP phones and wireless
access points, which you may want to power through the G350.
In the G250, PoE service is provided by eight fixed ETH LAN PoE ports on the chassis.
Note:
The G250-DCP does not provide PoE service.
Note:
The inline PoE feature enables you to power data devices through the Branch Gateway. Power
is distributed between the PoE ports, according to configured priorities. You configure the power
priority on each port. Distribution is calculated from the actual power consumption.
An automatic discovery system detects when powered devices are connected to and removed
from the PoE ports. Automatic load detection:
Tests whether the device connected to the port requires remote powering
●
Controls the power injection to the wires
