Hi

I have a 3640 router, which is continuously rebooting. When I break the booting process, it goes to the rommon mode. As long as it is in the rommon mode, it is fine. Otherwise it keeps on rebooting.

Can someone give me an advice how to stop this please?

Thanks in advance!

Hi

Well, I am unable to give any command as it keeps on rebooting. But I will try what you have said below, which is uploading a new IOS. That'll be a good move.

I will try this when I go to work tomorrow :)

Thank you so much!

Bad memory. I've had this a couple different times and it was always bad hardware.

Are you sure you have the proper amount of memory to boot the version of code you have?

Yes, because this router had been using in a different location.

But it could be a hardware problem becuase it was brought from another country. So I'm not sure if anything damaged on the way.

I don't think that the uploading of new IOS would solve the issue. You can try but the sure shot is the hardware issue.

Thanks,

Hi Stanly

Thank you so much for your post. It stopped rebooting. Therefore I could give some commands and get some output, which I posted above. Hope you will be able to get some idea from that and tell me what has gone wrong in my router.

Thanks in advance!

Hi

Thank you very much everyone for helping me to solve my problem. It was a hardware problem. I removed the NM from the slot it was connected to and plugged to a different slot and it worked.

Many thanks to everyone again!!!!
