Ways to Reset a Zyxel Device without a Reset Button
You can use the following ways to reset a Zyxel Device without a reset button to its factory default settings.
Web Configurator of the Zyxel Device Gateway
You can use this method if the Zyxel Device is connected to a Zyxel Switch with a Neighbor Reset function.
1 Log into the Zyxel switch’s Web Configurator. Go to Monitor > Neighbor, and then click the Restore button to reset the Zyxel Device to its factory default settings.
2 A pop-up window asks you to confirm that you want to reset the Zyxel Device to factory default. Click OK to proceed with reset. A count down starts.
Nebula Control Center
If your Zyxel Device is registered with NCC, you can unregister it to reset it to its factory default settings.
1 Go to Organization-wide > License & inventory > Devices tab in the NCC portal.
2 Select the Zyxel Device you want to remove, then click Actions > Remove from organization.
3 Click the Yes button to confirm.
Starting and Stopping the Zyxel Device
Here are some of the ways to start and stop the Zyxel Device.
method | description |
|---|---|
Turning on the power | A cold start occurs when you turn on the power to the Zyxel Device. The Zyxel Device powers up, checks the hardware, and starts the system processes. |
Rebooting the Zyxel Device | A warm start (without powering down and powering up again) occurs when you use the Reboot button in the Reboot screen or when you use the reboot command. The Zyxel Device writes all cached data to the local storage, stops the system processes, and then does a warm start. |
Using the RESET button | If you press the RESET button on the back of the Zyxel Device, the Zyxel Device sets the configuration to its default values and then reboots. Some models do not have a RESET button due to feature differences. |
Disconnecting the power | Power off occurs when you turn off the power to the Zyxel Device. The Zyxel Device simply turns off. It does not stop the system processes or write cached data to local storage. |
The Zyxel Device does not stop or start the system processes when you apply configuration files or run shell scripts although you may temporarily lose access to network resources.
Mounting Height Reference
When mounting the Zyxel Devices, follow these guidelines:
• Ensure a clear line of sight between the Root AP and the Repeater
• Position both Zyxel Devices perpendicular to the ground and facing each other
• Install them at the recommended height listed in the table below
Distance between Root AP and Repeater (km / mi) | Minimum Mounting Height (m / yd) | Recommended Mounting Height (m / yd) |
|---|---|---|
1 km / 0.62 mi | 2.21 m / 2.42 yd | 2.7 m / 2.95 yd |
2 km / 1.24 mi | 3.13 m / 3.42 yd | 3.8 m / 4.16 yd |
3 km / 1.86 mi | 3.84 m / 4.20 yd | 4.6 m / 5.03 yd |
4 km / 2.49 mi | 4.43 m / 4.85 yd | 5.3 m / 5.80 yd |
5 km / 3.11 mi | 4.95 m / 5.41 yd | 5.9 m / 6.45 yd |
For stronger signals in remote US environments, select channel 36 to 48 and channel 149 to 165 to enhance the wireless bridge signal.For outdoor deployment in the EU, ensure the operating channel is set within 100 to 140 to comply with local regulations.
