Rb433 not working

Zapnologica · Mon Oct 25, 2010 9:47 am

Hi there,

I have a RB433 that stopped working.

I find it very strange. if you put the power in, it boots up, (the lights flash and the speaker beeps)

But once it is booted no network interfaces work. If u plug a lan cable into it, none of the lights turn on and i cant access the RB?

What could be wrong?

You need to connect the sieral cable to your computer and have some kind of Terminal program so you can access the board(PuTTY, Hyper Terminal, etc.). If you don't have a console port on your PC, you will need a USB to Console adapter. Use the settings of:
Baud:115200
Bits: 8
Stop: 1
Parity: none

Everything by the baud rate is default in most terminal programs.

ok ok, i figured it out,

In putty i choes serial then chose com2 and click connect.

Its not working but i also noticed the light on the usb-com converter is not on?

When should this light come on? when u plug it in, or only once the connection is made?

experiment for 20 minutes, only then post again

we can't know what kind of serial converer you have, or if it even works

Ok u right, haha

K i been playing, turns out i have to reboot the router and only then will stuff display on the screen

I get this :

Press any key within 2 seconds to enter setup

RouterBOOT-2.20
What do you want to configure?
   d - boot delay
   k - boot key
   s - serial console
   o - boot device
   u - cpu mode
   f - cpu frequency
   r - reset booter configuration
   e - format nand
   g - upgrade firmware
   i - board info
   p - boot protocol
   t - do memory testing
   x - exit setup
your choice: refresh

I have tried all the logical ones, but how do i get to the console? i want to rester routerOS settings, maybe the enterfaces got disabled?

Or am i on the wrong track? What am i looking for in here? Cause it is clearly working fine?

I have tried uploading new firmware via ethernet but it gives an error:

Upgrade firmware options:
   e - upgrade firmware over ethernet
   s - upgrade firmware over serial port
your choice: e - upgrade firmware over ethernet


trying bootp protocol... OK
Got IP address: 192.168.1.4
resolved mac address 40:61:86:14:9B:6F
transfer started ....................... transfer ok, time=4.99s
invalid upgrade file id

Ok for some reason you are going into the boot loader when you start up the board from some reason. Press 'o' to load up the boot devices and tell it to boot from nand. That will be the flash chip and is what you want.

Ok if i dont push a button and just let it boot. it displays this:

RouterBOOT booter 2.20

RouterBoard 433

CPU frequency: 300 MHz
  Memory size:  64 MB

Press any key within 2 seconds to enter setup..
loading kernel from nand... OK
setting up elf image... OK
jumping to kernel code
Starting...
Starting services...

it stops at starting services. No terminal?

Ok, so i plugged my laptop into annother rb433 (working one) and if i wait the terminal comes up.

So that must mean the software on my one is fd?

And i cant upload new firmware?

Try netinstall and see what happens.

I did that,

I booted from ethernet, and then netinstalled the new firmware

and it seemes to work.

Thanks so much, I have learnt allot about the console, its quite easy, Im busy fixing an old rb111 that i found on a mountain somewhere, loading routeros on it again cause its key was lost.
