I have been looking at the Cisco Hardware docs and I can't find anything on the proper way to setup a 2 switch stack for Stackwise redundancy and Stackpower redundancy. Everything details 3 or more switches. Does anyone have some insight?

You just connect stack port 1 on the first switch to stack port 2 on the second and vice versa for both power and stackwise. The stackwise cables end up looking crossed over each other.

Thanks Bradford. That was what I was thinking but just trying to make sure I am following recommended setup. Appreciate the confirmation!

Crossovers (sw1 port 1 to sw2 port 2 and sw 1 port 2 to sw 2 port 1) are probably more common, but at least for StackWise, it will also work sw 1 port 1 to sw 2 port 1 and sw 1 port 2 to sw 2 port 2. I think StackPower doesn't really care either, as long as you complete one or both rings.
BTW, StackPower has limitations to how much amperage can flow through the power cables. You need to take into account maximum power draw per switch and where you place power supplies. This gets a little tricky when you consider a power supply failure.

Hi Healthtrans_2
Can you please tell me one thing
Is it safe to plug the power stacking cables while the stack switches are power on?
What is the recommended way?
Your reply will be highly appreciated.
Best Regards

I just found this. Is the same for 2 2960-s switches?
