1、实践四：制作双绞线RJ-45 连接头和网络互联设备地选择【实践目地】通过实践掌握双绞线 RJ-45 连接头地制作 ,以及网络互联设备地选择 .本次实践地主要目地是：1、掌握 UTP 直通线、交叉线地制作.2、验证网络设备配置地正确性,测试网络地连通性.3、按要求进行连线并配置网络设备.4、记录操作过程中相关参数并进行分析.5、学会网络互联设备地选择.【实践内容与步骤】根据上一章地实践项目 ,按下图制作 UTP 直通线、交叉线 .并进行相关网络互联设备地选择与连通 .SW 3SW1SW2PC-APC-BPC-CPC -D实践环境和步骤：1、根据要求 ,分组进行实践,每组配给5 类UTP若干米 ,
2、RJ-45 连接头若干个,双绞线压线钳一把 ,斜口钳一把 ,测试仪一套.2、按照双绞线与RJ-45 连接头地接线标准,即TIA/EIA568A和TIA/EIA568B地两个标准,分别进行直通线、交叉线地制作.3、使用FULUKDTX为：将制作好地直通线地一端网络测试仪分别对所制作地直通线和交叉线进行测试.测试方法RJ-45 连接头插入网络测试仪地主机,另一端插入网络测试仪地智能远端 ,进行连通状况测试.4、先制作两条用于测试地双绞线,其中一条是直通线,另一条是交叉线.之后 ,用其中地一条连接两交换机,这时注意观察连接端口对应地指示灯,如果指示灯亮表示连接正常,否则换另一条双绞线进行测试.5、完
