Hi ,

I have two c3560 switches in stack i want to upgrade the IOS .please let me know the steps to follow

Hello

Are the 3560's clustered not stacked?

Any how - In a stack, - Upgrade the stack master then the others switch will get upgraded automatically.

Please alow a sheduled change control window to do this, if running in production environment

Ok, for the 3750 series follow this doc step-by-step:

You need a maintenance window to do this and reboot the stack.

Yes am doing it on Green zone only ... i want to know during the reload both switches come back live correct , because am doing it for remote site there is no local support.

In most cases, the switches come back fine after the upgrade. But you may want to have a local resource available just in case. Also, if it is possible and you have spare switches, you may want to test it before doing in in production. Make sure the new image is fully loaded and verified on the flash with no error messages before you manually reboot the stack.
