Hardware MikroTik hardware general

Help me. I have a big problem for me. I was type in terminal of my routerboard 3.30 “/system routerboard upgrade”, and now, my RB411U doesn’t turn up. The led on RJ45 PoE conector, blinks in green, and LD501, 502,503,504 and 505, doesn’t light, and don’t beep after 5-10 seconds.

That could have happened?.

There are a video thats show my problem:

What does the console port say when you reboot by removing power and plugging power back in?

Connect a serial cable to the serial port on the board: http://wiki.mikrotik.com/wiki/Manual:First_time_startup#Serial_Cable
Then boot the board. What output does the serial console show?

And this is all. Loop, loop, but my RB doesn’t boot.

perfect video of the board that tries to boot up from ethernet :slight_smile:

there are 2 options - connect console and try to set it to boot from NAND and see if it boots up, or reinstall it using netinstall tool.
