Restart & Factory Reset

After each button press, the system waits 1 to 5 seconds for the next button event. If an invalid button combination is detected, the system provides negative feedback by blinking the red LED rapidly five times. The following table lists the reset button functions.

Phase	Phase Owner	Button Function	Initiated Task	LED Feedback
Phase 0	Power off	No function	Not Applicable	Not Applicable

Phase 2	MELD controlled	Short press	Graceful Reboot	4 x green/red (Fast, 4 Hz)
		long press (5s)	Factory reset with kept IPv4 address	4 x green/red (Fast, 4 Hz)
		3 x short press	Graceful Shutdown	Green / red blinking until shutdown has been completed. Off once done. (Fast, 4 Hz)
		5 x short press	Set default IPv4 address temporary till reboot	4 x green/red (Fast, 4 Hz)
Phase 3	Application controlled	Same as in phase 2

The MGU3 has an external button (hole in the front) to make a HW reset of the board.

When the reset button is pressed and released, the reset line to the Device Processor (DP) is pulled which causes an immediate restart of the DP and reboot of SW.

Pressing the Reset button on the front of the Media Gateway for 5 seconds will reset your Media Gateway to its factory default factory settings.

Note: Using HW reset on a running live system reset should only be used as a last resort, since there is a risk of corrupting flash file system and/or configuration data.
