No, I don't see that described either.

So, you have two Intel GigE interfaces, with separate RJ45 sockets. Is the Realtek R8152 interface for the POE switch then? That chip only does 10/100. It's also USB2, so max 480Mbit/s.

That was our initial concern. The purpose of this system is to try to eliminate the Electrolux TravelPower we use to generate A/C off the engine. We can do this now that we have removed the last bit of A/C equipment. And to try to eliminate as many cables and connectors as we can. We have already used PoE with our GigEVision cameras. So that is not new. Finding that the PoE is just one interface was not a happy surprise.

Right. Are the four POE ports maybe also 10/100 only?

PoE in a vehicle environment has it's gottchas. If the equipment that is powered has a long startup time (like a high-end GPS with an IMU), you must wait that additional time each time you restart the PC supplying the power.

I guess a separate POE switch is not an option? /Per -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
