2.6.3 Connecting Ground Cables

Grounding is a key step in device installation. The ground cable of a device must be correctly
connected to protect the device from lightning, electromagnetic interference, and electrostatic
charges. Outdoor APs support built-in surge protection on all interfaces, but the surge
protection works only when the outdoor APs are grounded.

l If a PoE adapter is used in outdoor scenarios, it must be installed in a waterproof box.
l Tighten the component b of the PG connector to the AP with a tightening torque of 2.5 Nm,
and the component d to the component b with a tightening torque of 1.8 Nm.
The ground cables must be connected to a group of ground bars.
