I have been trying to make a stack with two 2960S. They have the same IOS but they behave as they were not connected.
One is in production and I am attaching a brand new one to it; in the one that is in production I get these 2 messages:
FlexStack Module SmartChip Authentication Failed

I tried switching the modules and the outcome is the same, so I think the modules are ok.
What to you recommend, is there a way to bypass this authentication?
Thanks for your help,
I've seen this before and I've fixed this (several times) but you do you really want to know how I did this?
Power down the switch and re-insert the stacking module is one method. Make very sure the s_crews are secure (and not just finger-tight). If the error message returned, I would power down the switch, remove the stacking module and WHACK the flat side of the stacking module on a surface (NOT the intention of breaking the module) and re-inserting the module back.
I pray you don't have to result in the 2nd method.
I upgraded to 15.0(2). I'm not sure what version I was on before.
Even after the IOS upgrade I still had one faulty module that I had to return. I probably had four modules total give me grief and the IOS upgrade fixed all but one of them.
Fortunately, I had another switch so I installed those and I am migrating the connections to this new pair of switches. I think a reload would have help, but this switch is in production.
