Yesterday after a reset to default through routeros my rb433 dont boot , now i have 4 led lot, i used rs232 and i got bootp protocol failed, also if i try to get into bios by pressing a key in the startup, it doesnt respong, help me please
Have you tried to Netinstall?
yes but i cant change the boot device, i dont know why but i cant enter bios settings i think that the kernel isnt loading
also the user led lit, that means that the kernel is loading? but it stays in that condition for hours, i mean 4 leds and the user led are lit, no ethernet connection and also sometimes the orange led on ether2 is lit
If netinstall does not work you should email support@mikrotik.com and possibly RMA the board.
i will return it to local reseller, thank you
