Hi all,

I have 6500 series switch. When I switch on, it directly go to rommon mode.

I am going to explain the whole story,

When I buy that switch, the switch had catos. I don't know how to use catos, so I am trying to install ios to that switch. When I install ios to that swich, I wrongly format flash card. So existing catos also gone.

Sorry for my poor english.

Please explain me how to install ios.

Please help me...

Hi Than,

Which supervisor engine do you have right now. If its Sup 1 or 2, you will be better off using the x-modem and transfer the smalled CAT-OS image to sup and back it up. Once its up and running you can use the CatOS to IOS migration procedure.

For Cat6500 recover, Please use the link below :

For CAT-OS to IOS conversion, use the link below :

If you have SUP720 or SUP32, you cannot use X-MODEM and the only way to recover them is to use a Flash card. Check with your networking friends if they have a flash with either CAT OS or IOS loaded on it.

HTH,

Hi Amit,

Firstly I try to recover cat 6500 catos via xmodem command. But it was not successful. I don't know why. I also don't know which catos should I choose. So I download cat6000-sup.5-2-1-CSX cat os and used it . May I know is it correct cat os for that series.
