Re: RouterBoard RB411 damaged?

Yes, occured because of overheating!

P.S. Siemens give warranty for their devices only if the working temperature didn't exceed 40 (Celsius). I guess there is some reason for that. Their PLC components have similar parts to RouterBoards (CPU,RAM,Flash), but work for many many years.
