4.2.5. Reset button

Reset button

Fig. 4.6: Reset button

The Reset button is placed close to the screw terminal and it is labeled “Reset”. Use a blunt tool no more than 1 mm in diameter (e.g. a paper clip) to press the button.

Keep it pressed for at least 3 seconds for reboot and at least 10 seconds for a factory reset. The start of the factory reset is confirmed by all LEDs lighting up for one second. The button can be released afterwards.

[Note]Note

If the button is being pressed at least 15 seconds until all LED diodes blink red, the recovery procedure is started. The recovery image can be provided on demand and a special procedure utilizing the TFTP transfer from your computer is required. Contact our technical support team for more details.
