hAP AC powered by hEX POE

Will the hEX POE power a hAP AC with POE when the hEX POE is powered with a 48V power supply? I understand that the hAP AC is a passive POE in device and I’ve seen some mentions of crossover cables on this forum.

Also, will the hEX POE power an 802.3af compliant camera (with the 48V power supply)?
