1、用console电缆连接PC机与要恢复的cisco3550交换机，打开超级终端 2、拔下交换机电源，按住前面板mode按钮（前面板就一个按钮，在机器左上方）接通电源，等到前面板所有接口指示灯全亮，同时system指示灯停止闪动时松开按钮（大约30秒），松手后system指示灯会闪动。 3、此时超级终端会出现以下提示： The password-recovery mechanism has been triggered, but
is currently disabled.  Access to the boot loader prompt
through the password-recovery mechanism is disallowed at
this point.  However, if you agree to let the system be
reset back to the default system configuration, access
to the boot loader prompt can still be allowed. Would you like to reset the system back to the default configuration (y/n)? 按y回车，按y后设备会擦除配置文件即：config.text和vlan.dat文件会被删除。提示信息如下： The system has been interrupted, and the config file
has been deleted.  The following command will finish
loading the operating system software:     boot switch: 4、在switch:提示符下输入help或？回车可以查看可以使用哪些命令 switch: help
