1 Preparing for installation
WARNING!
Install the AP under the guidance of technical engineers read this chapter carefully before and
installation.
Examining the installation site
Examine the installation site before installation to ensure that the AP will work in a good
environment.
Installation site selection
T installation site must be selected according to the network planning and technical requirements he
of telecommunications equipment, with factors such as climate, hydrology, geology, earthquake,
electric power, and transportation taken into consideration.
Determine the installation location by observing the following principles:
The AP will n be exposed to moisture, high temperature, dust, harmful gases, ot
electromagnetic interference sources (high power radars, radio stations, or electrical
substations), unstable voltage, heavy vibration, and loud noise.
The location is not water seeping, water soaking, and condensing.
The location is away from inflammable and explosive substances.

Power supply
Power the AP by using a power injector. No power injector is provided with the AP. You can
purchase an H3C power injector for the AP. See "Powering the AP by using a power injector" for the
connection method.
1-2
Grounding and lightning protection
The AP must be reliably grounded. Make sure the grounding points of the grounding conductor of
the AP, lightning arresters, PE wire of the power cord, and antenna support are separate from each
other, make good contact, and are securely connected and treat with corrosion protection.ed
Ground resistance
The ground resistance is typically required to be less than 5 ohms, and less than 10 ohms in an
area with less than 20 thunderstorm days a year. For a piece of angle steel buried in the earth as a
grounding conductor, the ground resistance is required to be less than 10 ohms. In an area with a
higher ground resistance, reduce the ground resistance by using brine or resistance reducing agent
around the grounding conductor.
The top of the grounding conductor must a minimum of 0.7 m (2.30 ft) away from the ground be
surface. In cold areas, the grounding conductor must be buried below the frozen soil layer.
Grounding conductor
If a grounding strip is available, connect the yellow and green grounding cable to the grounding strip.
To make a grounding cable, make sure the cable has a cross section area of a minimum of 6 mm-2
(0.01 in2) and a length of no longer than 3 m (9.84 ft).
If no grounding strip is available, bury a piece of angle steel/steel tube a minimum of m (1.64 ft) 0.5
long in the earth to act as the grounding conductor. must be zinc plated. In the case of a piece of It -
angle steel, the size must be a minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). In the case of a
piece of steel tube, it must have a wall thickness of a minimum of 3.5 mm (0.14 in). Weld the
grounding cable of the AP onto the grounding conductor and use anti erosion treatment on the -
welding joint. With a cross section area of a minimum of 6 mm-2 (0.01 in2), the grounding cable must
be as short as possible and must not be coiled.
Make sure the grounding terminals of all the lightning arresters of the AP and the peer devices of
the AP are reliably grounded.
Ground lead
A ground lead is a metal conductor connecting a grounding net and a grounding strip. The
grounding cable of the A must be connected to the grounding strip. The ground lead must be 30 m P
(98.43 ft) or shorter. A piece of zinc coated flat steel with a cross section area of 40 × 4 mm (1.57 × - -
0.16 in) or 50 × 5 mm (1.97 × 0.20 in) is recommended. Connect the grounding strip and the ground
lead of the AP through the yellow and green grounding cable with an area of 35 mm 2 (0.05 in2), or
weld them directly. Use anti erosion treatment on the welding joint.-
Power grounding (AC)
Use a power cord with a protective earth (PE). Do not use a power cord with only an L line and an N
line.
The neutral line of the power cord must not be connected with the PGND of other communications
equipment. The L and N lines cannot be connected.
Lightning rod
The lightning protection grounding (for example, the grounding of the lightning rod) must be
connected to the grounding conductor of the equipment room.
The lightning rod must installed high enough to protect the AP and its antennas.be
In plain areas, the shielding angle of the lightning rod must be less than 45 degrees. In mountainous
areas or lightning areas, the shielding angle must be less than 30 degrees.
Ethernet cable
Use a shielded twisted pair cable for outdoor installation. Make sure the devices at the two ends of
the cable are reliably grounded.
If a metal tube is used, make sure the Ethernet cable is reliably grounded at both ends of the tube.
