Physical buttons

Power

The front button is not generally useful. If pressed for two seconds, it turns off the Gateway in a controlled manner without the need to turn it off. When the Gateway is turned off in this way to start it later it will be necessary to press the front button again (turning it off and on again will not start it)

Reset

The reset button is not generally useful. It can be pressed with a needle through the small hole in the case and is only used to immediately remove power from the system (bypassing the UPS and instantly shutting down the system in an uncontrolled way)
