Loading IOS on 3750

Unanswered Question
Jun 1st, 2007

I have a 3750-48-ts that I need to load the .bin image file into flash. I have no image file in flash currently. I've tried two different term emulators, connected to console to load it, but neither will pass the file to my switch.

I have this problem too.

Hi Friend,

Are you in rommon mode? If you have an access to the switch you need to try tftp upgrade if your switch is in rommon then have you tried xmodem?

If you are in rommon have a look at this link


If switch is not in rommon then try tftp

Hi Friend,

While performing xmodem what error you are getting? Can you capture everything on hyperterminal and post it here?

I get no errro. The dialog window appears that show my image to be received, but no packets/data is passed. My console settings are 9600, 8, none, 1, none.

Thanks for the article. I get the message now on my term session: "line to large" and it stops.

There also is an error msg that reads: "xmodem: bad file number"

It's working now. I was receiving instead of sending.!!! Brain lapse.
