Comprehensive PoE Guide

In BICSI Bytes, Newsby

The Ethernet Alliance has recently published a very comprehensive White Paper to understanding the latest IEEE Power over Ethernet (PoE) standard – IEEE 802.3bt.

This is a substantial 61 page technical document that addresses many aspects of PoE such as PoE Classes and their cable requirements; power detection; and performance parameters including operating power, inrush and current unbalance.

While much of the document would probably be beyond the scope of the needs of most BICSI members, it’s an excellent reference document to go to when you need detailed information on PoE.
