華爲S9306清除console密碼，注意：如果是雙引擎的話，一定要撥掉一塊引擎（否則兩塊引擎總在同步，破不了密碼），然後開機，按CTRL+B進入BootRom模式，密碼有可能是7800、9300等。
然後按照以下方法進行密碼破解，注意不要選11重啓交換機。
清空交換機配置：
再輸入reset saved-configuration；
顯示The configuration will be erased to reconfigure.Continue?[Y/N]； 輸入Y，回車（停留時間長會閃掉）；
這樣，配置文件已清空，然後就是重啓了，輸入reboot；
reboot的時候會提示是否保存配置的，需要選擇N不要保存配置； 重啓過程時間較長。
