Loading IOS through Console

cmccul002

I have a 3640, that was in Rommon mode when recieved. I have the IOS on my PC and I used Xmodem command to send the IOS through the Console port. The sending took 35 mins, now HyperTerm shows

program flash location 0x*********


the location numbers are changing, but how long should it take?

A long long long long long time.

And a lot longer if you didn't make the config change to transfer at 115k

The trick is to XMODEM the smallest image you have. Then once that boots, use TFTP to get your real image.

Mike is right. I would suggest you go get a nice fresh cup of coffee... from Columbia. It should be done by the time you get back.

Yep! Mike is right. But, you are learning and will not ever forget this experience!

I did the same thing....once.

3640 supports PCMCIA flash memory cards, see the 36xx hardware guide:

And particularly the part pertaining to configuring flash memory:

I have had the pleasure of the console reload with XMODEM but I was unaware of tftdnld
this works a lot quicker. I used this other day and it worked great.

Thanks, it did finally get done


When it was done and reloaded it came to a ts1> prompt, and when I tried enable it prompted for a password.

I tried the Password Recovery here http://www.cisco.com/warp/public/474/pswdrec_2500.html

It was late, but i think i replaced the secret password and it seemed to work, so I think it went ok. Ill post back tonight if I have any issues. Its usually easy to google to find help.

This is my first time with cisco equipment, but so far i like it

Good advice from Mike. I suggest a good cushion and a pot of tea!

Not all of them support TFTP from ROMMON. Newish ones do but older routers/switches don't.
