H3C LS-5120-24P-EI交换机忘记密码无法进入Boot菜单，如何恢复出厂设置？

我们库房中有一台较旧的H3C LS-5120-24P-EI交换机，目前设备正常启动但系统提示输入登录密码，原密码已无法找回，尝试开机过程中按Ctrl+B键希望进入boot菜单以便进行密码恢复或设备初始化，但发现系统未弹出菜单，而是直接提示输入BootROM密码，请问在这种情况下是否还有其他方式可强制恢复出厂设置或跳过BootROM密码限制？目前设备内部配置不重要，只需要恢复到可用状态即可，希望了解这类设备在BootROM密码未知时的常用处理方法，谢谢weibo.com/ttarticle/p/show?id=2309405161889276756025weibo.com/ttarticle/p/show?id=2309405161889221968078weibo.com/ttarticle/p/show?id=2309405161888571850759weibo.com/ttarticle/p/show?id=2309405161888962183350weibo.com/ttarticle/p/show?id=2309405161890799288333weibo.com/ttarticle/p/show?id=2309405161889855569987weibo.com/ttarticle/p/show?id=2309405161888072990741weibo.com/ttarticle/p/show?id=2309405161888722845775weibo.com/ttarticle/p/show?id=2309405161888131448855weibo.com/ttarticle/p/show?id=2309405161889381351462weibo.com/ttarticle/p/show?id=2309405161889163247799weibo.com/ttarticle/p/show?id=2309405161889972748401weibo.com/ttarticle/p/show?id=2309405161889616232621weibo.com/ttarticle/p/show?id=2309405161888010076216weibo.com/ttarticle/p/show?id=2309405161889914028121weibo.com/ttarticle/p/show?id=2309405161888844480597weibo.com/ttarticle/p/show?id=2309405161888605405217weibo.com/ttarticle/p/show?id=2309405161889674952872weibo.com/ttarticle/p/show?id=2309405161888551141477weibo.com/ttarticle/p/show?id=2309405161888282706127weibo.com/ttarticle/p/show?id=2309405161890686042271weibo.com/ttarticle/p/show?id=2309405161890559950928weibo.com/ttarticle/p/show?id=2309405161889020903628weibo.com/ttarticle/p/show?id=2309405161890266611714weibo.com/ttarticle/p/show?id=2309405161890748956809weibo.com/ttarticle/p/show?id=2309405161890912272542weibo.com/ttarticle/p/show?id=2309405161888223985816weibo.com/ttarticle/p/show?id=2309405161890618933383weibo.com/ttarticle/p/show?id=2309405161890446967009weibo.com/ttarticle/p/show?id=2309405161889561968777weibo.com/ttarticle/p/show?id=2309405161888689553559weibo.com/ttarticle/p/show?id=2309405161889393934422weibo.com/ttarticle/p/show?id=2309405161890501492838weibo.com/ttarticle/p/show?id=2309405161889201258617weibo.com/ttarticle/p/show?id=2309405161888102088800weibo.com/ttarticle/p/show?id=2309405161890329526339weibo.com/ttarticle/p/show?id=2309405161888781566145weibo.com/ttarticle/p/show?id=2309405161888630833183weibo.com/ttarticle/p/show?id=2309405161888458604716weibo.com/ttarticle/p/show?id=2309405161888508936336weibo.com/ttarticle/p/show?id=2309405161890090188884weibo.com/ttarticle/p/show?id=2309405161889440071748weibo.com/ttarticle/p/show?id=2309405161889851113666weibo.com/ttarticle/p/show?id=2309405161890321137889weibo.com/ttarticle/p/show?id=2309405161888165003325weibo.com/ttarticle/p/show?id=2309405161888991281167weibo.com/ttarticle/p/show?id=2309405161888903463114weibo.com/ttarticle/p/show?id=2309405161890853552315weibo.com/ttarticle/p/show?id=2309405161890383790102weibo.com/ttarticle/p/show?id=2309405161888400146554weibo.com/ttarticle/p/show?id=2309405161889738129490weibo.com/ttarticle/p/show?id=2309405161889142538278weibo.com/ttarticle/p/show?id=2309405161890866135248weibo.com/ttarticle/p/show?id=2309405161889792393331weibo.com/ttarticle/p/show?id=2309405161888341426324weibo.com/ttarticle/p/show?id=2309405161890807414909weibo.com/ttarticle/p/show?id=2309405161889737867279weibo.com/ttarticle/p/show?id=2309405161889322631232weibo.com/ttarticle/p/show?id=2309405161889914290333weibo.com/ttarticle/p/show?id=2309405161890387984459weibo.com/ttarticle/p/show?id=2309405161889620689095weibo.com/ttarticle/p/show?id=2309405161890148909166weibo.com/ttarticle/p/show?id=2309405161889557774591weibo.com/ttarticle/p/show?id=2309405161889796849666weibo.com/ttarticle/p/show?id=2309405161889499054216weibo.com/ttarticle/p/show?id=2309405161889045807268weibo.com/ttarticle/p/show?id=2309405161890568339472weibo.com/ttarticle/p/show?id=2309405161890211823627weibo.com/ttarticle/p/show?id=2309405161888248889577weibo.com/ttarticle/p/show?id=2309405161890442510400weibo.com/ttarticle/p/show?id=2309405161890627321922weibo.com/ttarticle/p/show?id=2309405161890736111802weibo.com/ttarticle/p/show?id=2309405161890677391479weibo.com/ttarticle/p/show?id=2309405161890090451149weibo.com/ttarticle/p/show?id=2309405161888374980678weibo.com/ttarticle/p/show?id=2309405161890031468694weibo.com/ttarticle/p/show?id=2309405161889679147053weibo.com/ttarticle/p/show?id=2309405161889083555897weibo.com/ttarticle/p/show?id=2309405161888311803972weibo.com/ttarticle/p/show?id=2309405161888492421201weibo.com/ttarticle/p/show?id=2309405161888869908703weibo.com/ttarticle/p/show?id=2309405161890505687331weibo.com/ttarticle/p/show?id=2309405161888433700871weibo.com/ttarticle/p/show?id=2309405161890031730832weibo.com/ttarticle/p/show?id=2309405161888748273850weibo.com/ttarticle/p/show?id=2309405161889259978977weibo.com/ttarticle/p/show?id=2309405161887947161773weibo.com/ttarticle/p/show?id=2309405161890207891525weibo.com/ttarticle/p/show?id=2309405161889973010541weibo.com/ttarticle/p/show?id=2309405161888806994128weibo.com/ttarticle/p/show?id=2309405161890153365522weibo.com/ttarticle/p/show?id=2309405161889503248500weib
