Using the RESET Button to Restore Default Settings for AR100&AR120&AR150&160&200 Series and AR100-S&AR110-S&AR120-S&AR150-S&AR160-S&AR200-S Series

Using the RESET Button to Restore Default Settings for AR100&AR120&AR150&160&200 Series and AR100-S&AR110-S&AR120-S&AR150-S&AR160-S&AR200-S Series

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

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

  • If you press the RESET 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 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.

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