Use a power cord with a protective earth (PE). Do not use a power cord with
only an L line and an N line.
z
The neutral line of the power cord should not be connected with the PGND of
other communications equipment. The L and N lines cannot be connected
5
Lightning
arrester
In plain areas, the protection angle of the lightning rod should be less than 45
degrees. In mountainous areas or lightning areas, the protection angle should
be less than 30 degrees. The lightning protection grounding (for example, the
grounding of the lightning rod) should be connected to the earthing conductor of
the equipment room.
6 Feeder
z
The antenna support is already prepared according to the design
requirements.
z
A feeder lightning rod is already installed and grounded according to the
design requirements.

Outdoor
lightning
arrester
Power lightning arrester, port lightning protector, and feeder lightning arrester
are recommended for outdoor installations. The power lightning arrester and the
feeder lightning arrester should be near the AP, and the network interface
lightning arrester should be near the peer device of the AP. The network
interface lightning arrester should be installed where the network cable is just
led out of the room.
8
Network
cable
Use a shielded twisted pair cables for an AP used outdoors. Ensure that the
devices at the two ends of the cable are well grounded.
After you have completed the preparations, you can start installing the AP. The installation of indoor
models is different from that of the outdoor models. For details, refer to 3 “Installation of Indoor APs” on
page 3-1 and 4 “Installation of Outdoor APs” on page 4-1.
