Just Provision the second swtich 

-switch 2 provision ws-c3850-48p

Connect the stack cable , and will join in auto , once the second switch is in the stack set the priority with the highest level 

-switch 1 priority 15


Hi Javier,

Do I just connect my second switch to the one that is on now or do I need to turn it off?

I have one in production and need to add the second switch do I need to shutdown the one that is on Or I can do it when is on and connect the second.

No you don’t need to shutdown the switch 1 just connect the stack cable in
both switches and then turn on the second one, will initiate the second ,
usually is not needed to reboot but I do prefer to do it after integration
to the stack
Just be sure that both has the same iOS version

I agree, but I would do switch 1 priority 15 on master before adding other switches. that way I know sw 1 will be a master in stack

Yes actually I stated that in my first comment :)
