Hi.
I bought RouterBOARD 800, after 1 day and ceased to function. Routerboard was powered through Jack, after 1 day of operation in the source all the burned fuse and has a short circuit at the input jack. Power was a “classic” source transformer with a voltage of 53V max load, under load output voltage is about 48V. I sent this routerboard to dealer, and there I was told that routerboard hight was damaged and that the warranty does not cover it. It was destroyed circuit Q10 no secondary part of the switched power supply. I have a chance this routerboard claim, or already have to change this dealer of RouterBOARD for a new one? Or make switched power supply to powered the routerboard directly :slight_smile:.

Thank you.

you can’t use “classic” transformer, you need to use “switching” power suply.

I’m sorry to correct: the transformer with rectifier and filter capacitor - just classic adapter, what is life for many years. We use this anywhere on our network (about 30 APs), and yet we have no a similar problem. Life of Switched power sourcesis 2-3 years only.
