Have you tried pinging the default IP (192.168.0.2) and configured IP? Try connecting to the Console port. What is the LED status of the controller? If LED status is RED or Completely off then the unit may need to be replaced. Try with a different power supply. If the LEDs are Green, try a different Ethernet cable on the ZD. Make sure to try port the ports on the ZD.
If you still have the issue, then you may need to contact our support team.
Yes I have tried pinging the default IP but no luck. LED status is both power and status is solid green as soon as you power it up. Tried both Ethernet ports no response. Also nothing on Console...
