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LEDs Cisco 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 Console Copyright (c) Cisco Systems, Inc. 1993-1998 All rights reserved.
