问题描述：

S2000 Series交换机忘记配置密码，怎么处理？在官网上看到断电重启---Ctrl+B，绕过配置进入到交换机，直接进入用户视图，键入设置密码命令，保存。这种方式更改密码，原来的配置还在吗？我还要原来的配置

重启进入命令行后，配置save 的话会不会保存原来的配置，需要将配置的文件先导出来。如下供您参考。

进入bootrom后，选择跳过当前配置启动后，将startup.cfg文件导出，并用TXT的方式打开，把密码的部分删掉后保存，重新导入设备，最后重启即可。

3 配置步骤

3.1 进入bootroom菜单清除Consle密码

通过conlse线和crt软件连接并登陆设备，然后把设备断电重启。控制台上会打印如下信息，当出现“press Ctrl+B”的时候快速按住“Ctrl+B” 进入botroom菜单

System is starting...
Press Ctrl+D to access BASIC-BOOTWARE MENU
Booting Normal Extend BootWare
The Extend BootWare is self-decompressing.......................Done!
BootWare Validating...
Press Ctrl+B to enter extended boot menu...

BotWare password: Not required. Please press Enter to continue.

Password recovery capability is enabled.

Note: The current operating device is flash

Enter < Storage Device Operation > to select device.

按住“Ctrl+B”进入如下菜单。选择“<6> Skip Current System Configuration”跳过当前配置启动,不同设备可能不是数字6，

3.2 如果不需要之前的配置信息的话

操作步骤：跳过启动文件后直接保存当前配置，再重启。

<H3C>save

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):（输入回车）

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Configuration is saved to device successfully.

<H3C>reboot

Start to check configuration with next startup configuration file, please wait.........DONE!

Current configuration may be lost after the reboot, save current configuration? [Y/N]:y

This command will reboot the device. Continue? [Y/N]:y
