Meraki APs dead after lightning storm

We had a giant lightning strike nearby and lost visibility of all MR45 APs on our Meraki dashboard. We found that each PoE switch that the APs were connected to needed replacing. Some were no longer getting power, others were just malfunctioning with lights going crazy on them. We replaced the switches and out of the 12 APs, 8 came back up but 4 did not. If the switches were on power surge protectors and the surge protectors looked good (all LEDs indicated no surge), how would some APs survive and others get fried, and how would all the switches get fried if on surge protection? Can the antenna in the AP take the strike and channel the surge down to the switch it's connected to, but not make it to the surge protector?
