I brought an OpenWRT One to IETF122 Hackathon. I plugged the 2.5Gb/s port into the IETF hackathon network, and the switch apparently has PoE (which I didn't care about). I hooked up the rest of the cables, including the USB power, but didn't turn it on yet. I was surprised when I opened the console that the system was running.... kinda.
With the cable in the PoE port, the device was in a reboot cycle. Getting to
just before the console shell starts, and then restarting. I can post a log
if that's useful to someone.
I guess because there wasn't enough amperage on the PoE port. I unpluged,
turned on the USB adapter and things were fine... so I reconnected the PoE
cable, and
the system crashed... back to reboot cycle! Oh. That's bad.
I "solved" the problem by inserting a my non-PoE switch in between.
I could have also swapped ports, it now occured to me.
I'm just mentioning this for the benefit for someone searching!
I suppose this is a hardware problem, and probably not solveable.
Maybe I could cut a trace, or maybe there is a zero-ohm resister I could
unsolder to disable PoE.
Maybe fixable in Two: prefer USB power if it's present.
But of course, when I started, it wasn't present, as I wanted the system to
be off until I was ready: I wanted to finish getting serial console alive
before I powered on.
The switch in question:
