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?

Sorry, but i don't understand your question.

Thanks.

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

This is the data of screen:

RouterBOOT booter 2.20

RouterBoard 411U

CPU frequency: 300MHz
Memory size: 32 MB

Press any key within 2 seconds to enter setup..
kernetl not found
trying bootp protocol.........................................................................................................................................................................failed

kernel loading failed


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

Thanks.

NetInstall the router.

Thanks fewi. Their response has been helpful for me.

Thanks again.

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

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.
