what's your firmware version? if it is newer than V200R012C00
the PNP button on the switch can be reused to reset the switch.
To restore the factory settings and reset the switch, hold down the button for at least 6 seconds.
To reset the switch, press the button.
Resetting the switch will cause service interruption. Exercise caution when you press the PNP button.

If you want to clear all service configurations and data files, run the following command to restore the switch to factory default in one-click mode.

In the user view, run reset factory-configuration.

The switch is reset and restored to factory default settings.
