When incorrect configurations result in a fault (for example, device login failure), you can press the RESET or RST button on the panel to enable the device to use default configurations in a restart.

Press the RESET or RST button for no less than 5s to restart the device with default settings.

• If you press the RESET or RST button for no longer than 5s, the device restarts without saving the current configurations and uses the original configuration file for the next startup. Therefore, save the configurations before pressing the RESET or RST button.

• If the device restarts with default configurations, the original configuration file still exists. After you perform configurations, save them to make them take effect. Otherwise, the device still uses default configurations in the next restart.

• Do not power off the device during the operation. Otherwise, the operation fails and the device uses the original configuration file for the next startup.

• The silkscreen of the reset button is RESET or RST, for details, see the device.
• What Can I Do If the Device Cannot Be Restored to Factory Settings After I Press and Hold the RESET/RST Button, You can manually enter and run the undo factory-configuration prohibit command on the CLI to enable the function of restoring factory settings by pressing and holding the RESET button.

Run the display factory-configuration command to display the factory configuration information.
