Huawei交换机清空密码(采用BIOS加载方式).docx

1.1 采用BIOS加载方式如果升级失败导致系统无法正常启动，则必须到现场采用BIOS方式进行版本回退。1.1.1 获取原版本的配套文件和原版本数据库文件步骤 1 获取原版本的程序包文件。从升级服务器的对应的主机路径下获取原版本的程序包文件。步骤 2 获取升级前备份出的数据库文件。请务必使用升级步骤中备份环节备份出的该主机的升级前原版本的数据库文件，否则可能导致配置数据丢失。-结束1.1.2 现场手动加载回退步骤 1 在PC上运行TFTP服务器应用程序，并配置好传输路径，配置方法请参见“Error! Reference source not found.的 Error! Reference source not found.Error! Reference source not found.”步骤 2 将串口线连接到设备与并将网线连接到设备的第一个以太网口。如果是V8R308硬件设备不需要执行步骤4，并请根据基本BIOS的版本号选择网线连接方式：Platform System start .
