1. 連接交換機的console口到終端或PC仿真終端。用無Modem的直連線連接PC的串行口到交換機的console口。
2. 拔掉交換機的電源.
3. 按住交換機上的Mode按鈕,與此同時,重新插上交換機的電源線.當交換機上SYST的LED長期亮的時候，可以鬆開Mode按鈕。
4. 再通過超級終端連接交換機。

這裏有一個有趣的地方，那就是你能夠選擇進入命令行接口模式並放棄剛纔的配置（0），你也能夠回頭重新再設置一遍（1），也能夠保存配置到NVRAM中並退出重啓（2）。這裏我選擇的是0，我們將不保存剛纔的配置並進入命令行接口模式（CLI）。接下來我們將介紹CLI。再重複一次，你可以在任何時候按下 Ctrl+C來退出安裝模式。
