华为S9306清除console密码，注意：如果是双引擎的话，一定要拨掉一块引擎（否则两块引擎总在同步，破不了密码），然后开机，按CTRL+B进入BootRom模式，密码有可能是7800、9300等。

然后按照以下方法进行密码破解，注意不要选11重启交换机。

清空交换机配置：

再输入reset saved-configuration；  

显示The configuration will be erased to reconfigure.Continue?[Y/N]； 输入Y，回车（停留时间长会闪掉）；  

这样，配置文件已清空，然后就是重启了，输入reboot；  

reboot的时候会提示是否保存配置的，需要选择N不要保存配置； 重启过程时间较长。
