网线在布线的时候，线芯通常都会分配工作，一方承担发送数据，一方承担接受数据，而在百兆网络和千兆网络的情况下，线芯的作用是不一样的。百兆网络是可以依靠4芯进行收发，而千兆是要依靠8芯来收发的。

　　同样的，当网络运用到网络监控PoE供电时，线芯分配的工作也是不同的，PoE供电交换机系统是需要4条芯来收发，4条芯来进行供电的，所以PoE供电交换机一定要选择8芯网线。

苏州交换机厂家飞崧浅析网线接POE供电交换机的线序是什么

PoE供电交换机的线序可以有三种：

1、网线中的4、5线为正，7、8线为负。

2、网线中的1、2线为负，3、6线为正。

3、网线中的1、2线为正，3、6线为负。

在实际布线中，好选择网线中的4、5线为正，7、8线为负进行供电，其他四芯用来传输网络。工业以太网交换机作为特殊类型的网络交换机产品,近几年来，由于监控行业数字化的快速普及应用，工业交换机开始迅速在安防领域普及，应用数量出现了井喷式的增长，为安防行业的发展，提供了强劲的源动力。number of substations and equipment, coupled with its perfect comprehensive functions, the amount of information exchange is large, and the information transmission speed and accuracy are required. In the substation integrated automation system, the monitoring system is very important and the key to ensure the reliable operation of the whole system. Substation automation system, after several generations of development, has entered the era of decentralized control system. Telemetry, remote signaling, remote command execution and relay protection functions are completed independently by field unit components, and these information are sent to the background computer system through the communication system. The integrated functions of substation automation are undertaken by the background computer system. The microcomputer protection, microcomputer monitoring and other devices in the substation are integrated into an integrated automation system through computer network and modern communication technology. It cancels the traditional control panel, meter and other conventional equipment, so it saves the control
