Here is a bribe for replies: thermal footage of deer.

I don't believe the failure coincided with a power outage on that switch, but I can't be absolutely sure of that (it was a couple months ago, I've been putting off...
One of my HDW5231R-ZE dropped off my DVR after a couple months running, I thought it was dead but after chasing it down, I discovered that it somehow changed IP to 192.168.1.50 from where it had been running (an an entirely different subnet). It should be running a somewhat older firmware...
