You can prebuild everything before they arrive - when you get the Order number just add the devices and go to Organization > Your Network > Switches > Switch Stacks and add them together in the dashboard.   Then we always coordinate things by switch MAC so we build the stack, rename the devices in the dashboard to something meaningful (like HUB1 11:76, where 11:76 is the last 4 of MAC), and then when the actual hardware comes in we match the dashboard name with the physical switch, connect them as defined in dashboard, plug em all in and go.   I would second the advice to connect them up locally first before going to the customer site. They take a while to update firmware and download  configs and (this only happened once) but there was breaking firmware update that took forever to get patched thru (had to do with hardware that shipped with old SSL certs during .. heartbleed I think?) ...

You didn't specify which model you have, but there is an open hardware recall on MS225/MS210-48LP/FPs.  From the notice ..   ".. We have also created an interim software mitigation. This mitigation can significantly reduce the likelihood of device failure for devices that have not had a high-temperature alert by increasing the operating speed of the fan. This mitigation requires both a firmware upgrade to MS 10.34 or higher, and then opening a support ticket. The tradeoff is that this solution will increase the perceived fan noise by approximately 40%."   https://documentation.meraki.com/zGeneral_Administration/Support/MS225%2F%2FMS210-48LP%2F%2FFP_Proactive_Replacement ...
