I installed a new eisy I acquired about a year ago to replace an ISY 994. In configuring it I restored the backup from the ISY. After it restarted, I got a message that I needed to kick off a manual upgrade from the configuration tab. I did this, and now 4 hours later I cannot connect to the eisy. The dhcp component of the router does not show it registered. If I look for a dhcp registration attempt in the log of the router, none shows up for the eisy.

I tried doing a reset using the multi function button on the eisy per the User Guide, but nothing happens. It doesn't matter how many times I push the multi function button, nothing changes. The light just stays blue. Unplugging the eisy makes not difference. The multi function button turns red when I plug it back in for a few seconds, and then it turns blue.

What do I need to do?

As I recall, in the last year there was a major OS upgrade and there were cautions on jumping many versions. Unless others chime in, I’m thinking you will need to contact UD via a ticket to get it in back in working order.
