My ISY944i stopped working after a power failure. I tried two different 5v 1A power supplies as I know this is a common failure, but the ISY is not pingable and none of my programs are reacting to insteon traffic. When I power it on, the power light is lit as well as the link light on the switch, but no RX/TX and my network management software doesn't see the mac address as being connected. If I power it on with the SD card removed, the error light doesn't turn on either.
I have another ISY944i that someone gave me when they switched to Zwave. Can I swap the SD card over? Or is it only possible to recover from a backup (which I do not have)?
