一 为什么需要清空配置？
在网络的运维中，会遇到设备下架的场景，需要将下架的设备挪到其它地方使用，那么下架前需要对设备进行配置清空处理。
二 如何清空设备配置？
清空配置文件。有如下两种方式：
1、通过命令行使设备以缺省配置启动。
执行命令reset saved-configuration清除设备下次启动使用的配置文件信息，然后重启设备，重启时提示保存配置，请选择“N”不保存。
代码语言：javascript复制<HUAWEI> reset saved-configuration
The action will delete the saved configuration on the device.
The configuration will be erased to reconfigure.Continue? [Y/N]: y
Warning: Now the configuration on the device is being deleted.
..........
Info: Succeeded in clearing the configuration in the device.<HUAWEI> reboot
slot 1:
Next startup system software: flash:/basicsoftware.cc
Next startup saved-configuration file: NULL
Next startup paf file: default
Next startup patch package: NULL
Warning: The current configuration will be saved to the next startup saved-confi
guration file. Continue? [Y/N]: n
Warning: The system will reboot. Continue? [Y/N]: y 2、通过BIOS/BootLoader菜单使设备以空配置启动。以下显示信息以CE6850EI为例。
进入BIOS主菜单，选择第4项，进入启动文件子菜单。
接着选择第2项，进入修改启动文件信息菜单。
