Take lightning protection measures on outdoor APs (the
outdoor APs have built-in 5 kV surge protectors. If
customers require a higher surge protection capability on the
Outdoor

feeder ports, they can purchase additional surge protective
AP
devices, which need to be separately grounded). The APs
should be located in the protection scope (within a 45-degree
angle) of a lightning rod.
Outdoor
When an AP is mounted to a pole, the distance between the
