Just so you know, the included basic Meraki support comes with best effort NBD RMA for the lifetime of the product, except for Outdoor APs which have a 1 Year warranty and some cameras, sensors and accessories (see details: https://documentation.meraki.com/General_Administration/Other_Topics/Returns_(RMAs)_Warranties_and_E... . This means if you call in and an RMA is determined it will ship as same day with NBD delivery. This can occasionally be delayed if you are late in the day or perhaps there is low stock on replacements.
Then the following 4 options are available that guarantee replacements within the time period stated and they each additionally offer an onsite tech option on top of that:
8x5xNBD - M-F, as long as the RMA is requested before local closing time you will receive your replacement the NBD, Excludes Observed Holidays. This basically turns the basic warranty support into a guarantee
8x7xNCD - Every day of the week as long as the RMA is requested before local closing time you will receive your replacement the next calendar day (aka including weekends)
24x7x4 - Every day of the year you will receive your replacement within 4 hours of the RMA request
24x7x2 - Every day of the year you will receive your replacement within 2 hours of the RMA request. This service level sometimes has geographic restrictions, make sure your vendor has the accurate address of where your gear is being installed when quoting.
You have to decide if your install is mission critical enough to need any of these.
