Hello All.

I have recently gotten a rb433.
I tried to start it. But its not working.
It boots up. And makes two beeps. All lights on the 3 ethernet ports flash while booting. Then nothing. The 5 leds on board are not lit. And only ether3 works by only flashing the 2 leds. Cannot connect to computer. When I connect a cable to ether1 and 2. There are no working lights. The lights only come on at ether3.

There is also a r52 wireless board. But there is no wireless to connect to.

I have googled alot. And tried to reset the board. By use of the push button. And the jumpers that needs to be shorted. This also did not work.

I also do not have the means for a serial connection.

I have very little knowledge of these boards. Please help.

Thanks in advance

You have already did what should be done at first place "reset button and jumpers", so you still have the only option, which is to get a serial cable and follow the instruction how to fix the bootloader.
