When I turn on my device, I only get the blue power light on the front and the solid blue light at the back next to Port A.  I cannot see the device on my router and I have tried using the iox finder with no luck.  I tried to do a factory reset (holding down the reset button for 30 seconds) and it is not working.  None of the status lights on the front are lighting up.  I tried replacing the power source with a known working 12v device.  I also removed and reformatted the SD card.  Any ideas?
