The Instant On is limited to 25 Devices per Site - does that only count AP`s or do a Switch also count into that Limitation?
I do have a site upcoming with about 18 APs and 6 Switches if I would go all "Instant On" I would have no option to add another AP in future. But fot this Customer I would not go for "normal" bigger Aruba lineup instead I would take 2530 Switches.
@MarcoG [updated]The 25 device limit is for AP's and switches in a single site. So you may want to create multiple site if you plan going above 25 devices.
