Adding second switch Meraki to Stack: Any Service Disruption?

[Rojo24]

Previously configured a stack with 2 Meraki MS-410-16 switches, already seen as stack associates in the dashboard. I moved them and only put one into production. Now I want to add the second member to the stack (the same switch used for initial stack configuration). I've installed and powered on this unit and will be connecting it to the first one using stack cables. Will it cause any interruptions in the services running on the first switch? Will either of the 2 devices restart? I'm inquiring to understand if there will be any service interruption, even if it's for a short period of time.

The switches may reboot during this process.

Thank you for your response, but 'The switches may reboot during this process' is stated in the Meraki documentation under the section "Physical Switch Stack Configuration Steps" In my case, this has already been done; the switches have been configured in a stack but only one has been put into production. Now, I need to add the second one

There should be no interruption as long as the new switch has downloaded firmware and configuration before connecting it.

I would still prepare and advise end users there could be disruption. I never like to assume in these instances as I have found assuming has always come back to bite me.

Yes, I know, that's why in the previous post I said that the switches can reboot during the process.
