My R510 that was a replacement from a prior Case #01430592, unfortunately, is experiencing the same issue with no power via ethernet.
Unfortunately, I did not get a chance to install it until yesterday, due to some unforeseen personal reasons. When I connect it using an ethernet cable (5e), the unit power lights do not turn on and unable to set it up. I tried calling the customer support and explained that this was a device that was sent to me in November 2022 when Lennar homeowners support was still active and they said they can no longer support me and directed me here. Can someone please help. I really don't know what else I can do at this point if there is no power on this device, unable to move forward.
