Reset button behavior

For those SmartNode devices that have a Reset button on the rear panel, its behavior is as follows:

•To restart the unit with the current startup configuration—Press for less than 1 second and release the Reset button. The SmartNode will restart with the current startup configuration.

•To restart the unit with factory default configuration—Press the Reset button for 5 seconds until the Power LED starts blinking. The unit will restart with factory default configuration.

•To restart the unit in bootloader mode (to be used only by trained SmartNode technicians)—Start with the unit powered off. Press and hold the Reset button while applying power to the unit. Release the Reset button when the Power LED starts blinking so the unit will enter bootloader mode.
