AP one configured manage by IC2, if AP one warranty expired, does it affected the push config to ap? in current situation ap out of warranty, all ap was offline.
Configuration cannot be pushed to the devices from IC2 after warranty is expired. Warranty expiration does not affect the configurations that have already been pushed into the devices.
You can purchase IC2 subscriptions beyond the warranty period: 1-Year InControl 2 Subscription - ICS-012
Meaning that device goes offline, but push config still exist in the AP, so does not affect broadcast ssid, am i right?
Yes, you are right.
