Lightning Protection Requirements

The AP can guard against lightning strikes. As an electric device, it may still be damaged
by too strong lightning strikes. Take the following lightning protection measures:
Ensure that the ground cable of the uplink optical host is in good contact with the

ground.
Ensure that the neutral point of the AC power socket is in good contact with the

ground.
It is recommended that a power lightning arrester be installed in front of the power

input end to enhance the lightning prevention for the power supply.
