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.
Clicking Maintenance > Shutdown > Shutdown or using the shutdown command
Clicking Maintenance > Shutdown > Shutdown or using the shutdown command writes all cached data to the local storage and stops the system processes. Wait for the Zyxel Device to shut down and then manually turn off or remove the power. It does not turn off the power.
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.
