I have an old RB4500G. A few days ago it started to beep (once in a couple of minutes) and blink all five port lights. I did netinstall and after that, it was booting normal again. I left it unplugged for a day and just now I plugged it in and it has the same problem - beep and flashing port lights, and it won't boot.
Is it a hardware problem and I can't fix it (keep in mind I already tried netinstall) or there is something I can do?
