Rb500 does not boot

Hi,

I have a rb500 with 532a daughter board. After updating to OS 5.6 and firmware upgrade to 2.18 my router does not boot. It gives an orange light. Tried resetting but did not work.

Before the router restarted the processor was showing 100% usage.

Please help.

Thanks.

  1. Try to connect Null Modem cable to COM port and check console output.

  2. Does RouterBOARD work without daugterboard?

Tried with serial cable does not show anything. Also tried with removing the daughter board.

Rb500 does not give the system boot beep

Thanks

Please make sure 115200 baud-rate is used with disabled hardware flow.

Yes tried that no use.

9600? other baud-rate?
