Avoid DC resistance unbalance in PoE systems

原先由 IEEE 分别于 1999 年和 2003 年批准的千兆以太网 (1000BASE-T) 和以太网供电 (PoE) 的两种网络技术已成为现在的规范。因约 85% 的现有布线同时支持这两种技术,它们在过去十年里获得了飞快的发展,因而现在有许多企业己经或计划在水平 LAN 环境中部署千兆以太网和更多的 PoE 设备。

However, standards-based certification may not be sufficient to guarantee reliable PoE performance.
