Have a query regarding switch stacks, if a stack member is temporarily removed from the stack and then a change made on another member what happens when it's plugged back in?

I provisioned the new switch as number 4 and copy/pasted the config from the one we're replacing which is number 1, only change was ports 37-48 are ...

ThanksBen
