Re: Cisco 3550 boot problem. switch boot but no prompt

Thanks God, I am back in business. The problem is solved.

A bad connection between the Mode button on the swith front plate and the mini-board was the reason I could not even get into the recovery mode. I don't exactly why it could not boot. But as long as I can get it back to work I am ok. I have a backup of my config.

Now I need to make sure the password-recovery service is enable.

here what I did

- Physically opened the switch,

-  Hold the mode button  (directly on the mini board) and reboot the unit – Release it when the light on top 1x went off

- Accept the message to reset to factory default

- type boot and voila problem fixed.

Re: Cisco 3550 boot problem. switch boot but no prompt

Now I know why I couldn't get the prompt after reboot my switch. Stupid mistake. I put the command NO EXEC under line cons 0.

I tested it on my home lab on switches and routers and got the same result. The solution is to use the recovery password trick for switch and router.

line cons 0

no exec

it means PROHIBITED ACCESS to console. So no prompt. Try it at home. It is fun.
