RouterBoard turn on power

I’m sorry if that doesn’t go to the correct area for this post.
I had a RB 3311UiAS-RM saved and these days I would use it at my provider, I updated it, applied the desired settings and went to the system / shutdown function, it turned everything off correctly and today when I turned it on, it doesn’t give any signal, no lights up, I have already changed the source and nothing to turn it on, has anyone been through this, any recommendations?

obs .: I’m using google translator.
