Hi,
If you had a problem with Cisco switch , in a stack, and the replacement switch is under a different IOS version you shoud do an upgrade or a downgrade.
In my case i downgraded the replacement switch to the same version of the existing switch:
1. download de 12.2(35) bin image from Cisco ( need Contract for that)
2. copy tftp://192.168.1.198/imagename.bin flash:
3. dir flash
4.boot system flash:/imagefilename.bin
boot system flash:c3640-i-mz.122-10.bin
boot system flash:c3640-i-mz.122-10.bin
boot system flash:c3640-i-mz.122-10.bin
Your switch should boot now with the new downgraded image..
copy tftp://10.1.1.1/iosimage.bin tftp:
copy tftp://10.1.1.1/iosimage.bin tftp:
copy tftp://10.1.1.1/iosimage.bin tftp:
