1、交换机基本操作,系统启动例程会初始化交换机初始启动利用缺省配置参数,1.启动前确认正确连接线缆和控制线2.接入电源3.观察启动顺序面板上的指示灯LEDsCisco IOS输出到控制台上的内容,交换机的初始启动,检查交换机指示灯(LEDs),交换机自检期间的端口指示灯,1.启动时，所有端口指示灯变绿.2.每个端口自检完毕，对应的指示灯熄灭.3.如果端口自检失败,对应指示灯呈黄色.4.如果有任何自检失败情况，系统指示灯呈现黄色.5.如果没有自检失败,自检过程完成.6.随着自检过程的完成,指示灯闪亮后熄灭.,交换机初次启动时的显示信息,控制台连接,Catalyst 1900 Management C
