Power Over Ethernet (PoE) Feature Overview and Configuration Guide

This guide provides an introduction to Power over Ethernet technology, the PoE standards, PoE devices, and how to configure PoE on your switch. PoE distributes both data and power over the same cabling. This eliminates the need for having one set of cables and outlets for data, and another set for power. Also, because the voltage and power requirements are much lower than for mains powered devices, the cabling and installation costs are significantly reduced.

This guide covers:

  • PoE (IEEE 802.3af)
  • PoE+ (IEEE 802.3at)
  • PoE++ (IEEE 802.3bt)
  • Allied Telesis high-power mode for IE300 series switches
