PoE (Power over Ethernet) Features

Introduction

This chapter describes the Avaya W310 PoE (Power over Ethernet). It provides the basic
procedures for configuring the W310 for PoE operation.
It contains the following sections:
•

Load Detection

• Plug and Play Operation
• Powering Devices
• Power over Ethernet in Converged Networks
• Power over Ethernet CLI Commands

Power Over Ethernet

The W310 switches provides IEEE 802.3af-compliant "Inline" DC power over the signal
pairs in addition to switched Ethernet on the existing LAN infrastructure for devices such as
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 W310 switches
are pre-configured to supply power according to the load detection criteria (see Load
Detection), so you can use it right out of the box. The W310 switches provide power over
standard Category 3 and Category 5 cables.
Load Detection
The W310 switches periodically check all ports, powered and non-powered to check their
status and the power status of connected devices.
The W310 switches will supply power to a port only after it has detected a suitable PD
(powered device, such as a W110) is connected to the port. The check consists of the W310
switches looking for a signature from the device that indicates it needs to supply power.
