Introduction
The Avaya G350 MM314 PoE media module provides Inline DC power over the signal pairs, in addition
to switched Ethernet, on the existing LAN infrastructure for devices such as IP telephones and Wireless
LAN access points. This allows you to deploy devices in the network that require power without
installing standard power cables in hard-to-access areas. The MM314 PoE media module provides power
over standard Category 3 and Category 5 cables.
The MM314 PoE media module is designed to comply to the specification of the latest draft of the IEEE
802.3af. For updates, see the Avaya Web site, www.avaya.com.
NOTE:
When you connect a non-powered device to a PoE port, the PoE port status alternates
between Searching and Fault. Ignore the Fault status.
Load detection
The MM314 PoE media module periodically checks all ports, powered and non-powered, to check their
status and the power status of connected devices. The module supplies power to a port only after it has
detected that a suitable Powered Device (PD) is connected to the port. To check, the media module looks
for a signature from the device that indicates that the device requires power.
