I recently used some Skylane 10G-BaseT SFP+ on a MS125 switch, worked just fine.
So they should work just fine on other Meraki switches as well (fingers crossed).
But please be aware that the 10G-BaseT SFP+ do get "hotter" then the normal fiber ones.
I dont think Meraki does it, but some manufacturers list a max number of these modules you should install in their switches. - But thats mostly the SFP+ only switches. I dont think I have seen it for normal access-switches. But just be aware that this problem is there.
