有時我們新接手的設備，或者因某種因素無法得知管理員密碼的情況，就需要進行密碼重置。下面介紹一下USG防火墻的管理員密碼重置流程。
前期準備：電腦+Console調試線纜+Console調試軟件
1、通過Console口連接設備并重啟設備。在設備啟動過程中，看到提示信息“Press Ctrl+B to enter main menu…3”時按下Ctrl+B，輸入BootROM密碼后，進入擴展段BootROM主菜單。
USG系列各登錄方式默認密碼如下圖：

3、重新設置管理員密碼，假設管理員為admin，密碼重新設置為Admin@12345。
復制

部分設備的BootROM版本不同，菜單也略有不同，根據實際情況來進行密碼重置操作。
