2. 拔掉交换机的电源.
3. 按住交换机上的Mode按钮,与此同时,重新插上交换机的电源线.当交换机上SYST的LED长期亮的时候，可以松开Mode按钮。
4. 再通过超级终端连接交换机。

[0] Go to the IOS command prompt without saving this config.

[2] Save this configuration to nvram and exit.
这里有一个有趣的地方，那就是你能够选择进入命令行接口模式并放弃刚才的配置（0），你也能够回头重新再设置一遍（1），也能够保存配置到NVRAM中并退出重启（2）。这里我选择的是0，我们将不保存刚才的配置并进入命令行接口模式（CLI）。接下来我们将介绍CLI。再重复一次，你可以在任何时候按下 Ctrl+C来退出安装模式。
Enter your selection [2]: 2
