文档适用产品型号：GSM7328FS,GSM7328S,GSM7352S 三层交换机

NETGEAR 三层交换机从固件版本V7.3.1.7开始新增了命令行恢复管理密码的功能。
下面将以GSM7328FS为例介绍NETGEAR三层交换机恢复管理密码的步骤。

1. 连接console线到电脑，并在电脑上打开超级终端。
   1. （Windows XP系统：开始 > 所有程序 > 附件 > 通讯 > 超级终端），连接描述的名称（N）：输入此连接的名字，如GSM7328FS，点击确定。
      
   2. 现在连接时使用的COM口，这里是COM5，点击确定。
      
   3. 配置COM口属性，GSM7328FS的COM参数为每秒位数9600，数据位8，奇偶校验无，停止位1，数据流空无，此参数只需要点击下面的“还原为默认值”按钮，点击确定。
      
      其他各个型号的COM口属性参数请参考交换机机身面板上的说明，一般位于Console端口下方。
      如下图为M4100的参数：115200,N,8,1。
      
2. 打开超级终端界面之后，给交换机加电，将提示下列信息。
