The installation site must be selected according to the network planning and technical requirements 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 not be exposed to high temperature, dust, harmful gases, 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

You can power the AP through PoE, or by using a hybrid copper-fiber cable or power injector. For information about powering the AP, see "Powering the AP."

No power injector is provided with the AP. Purchase a power injector from H3C as required.

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 treated with corrosion protection.

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 be a minimum of 0.7 m (2.30 ft) away from the ground 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 3.3 mm2 (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 0.5 m (1.64 ft) long in the earth to act as the grounding conductor. It must be zinc-plated. In the case of a piece of 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 3.3 mm2 (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 device 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 AP must be connected to the grounding strip. The ground lead must be 30 m (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 mm2 (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 be tall enough to protect the AP and its antennas.

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.

Installation tools

When installing the AP, you might need the following tools. Prepare the installation tools yourself as required.

Figure1-2 Installation tools

2 Installing the AP

IMPORTANT:

As a best practice to ensure wireless signal coverage, have the AP installed by technical personnel.

Pre-installation tasks

Before installing an AP, perform the following tasks:

· Connect the AP to the power source and the network. Examine the LED to verify that the AP can operate correctly. For more information about the AP LED, see "Appendix A Technical specifications, LEDs, and ports."

· Verify that cabling at the installation site has been completed.

· Record the AP MAC address and serial number marked on the rear of the AP for future use.

Before installing an AP, read the following guidelines carefully:

· The AP is large and heavy. Avoid bodily injury and device damage during the installation.

· If you install the AP on a pole, make sure the pole is vertical to the ground and iron components have been treated with corrosion protection. The installation height and position of the AP must comply with the requirements of the design plan.

· If you pole-mount the AP on the top of a building, make sure the AP does not project beyond the sides of the building.

· To avoid high temperature caused by exposure to the sun, install the AP in a place without or with less direct sunlight and take protection measures if necessary.

Before connecting cables to the AP, read the following guidelines carefully:

· Route cables according to the cabling design.

· Arrange cables firmly and neatly without crossing, twisting, or cracking them.

· Do not route cables together with high-voltage electric power pipelines, fire-fighting pipes, or lightning protection cables to avoid the electromagnetic interference.

· Use PVC pipes, iron pipes, Plica tube, or cable troughs for cable routing. Route cable pipes and troughs neatly against the wall and connect them through hoses or pipe joints at the bend. Secure cable pipes and troughs by using cable ties or angle steels at the spacing of 1 m (3.28 ft) to 1.5 m (4.92 ft) and ground the two ends in the case of metal tubes.

· As a best practice to avoid water accumulation, cut an opening at the bottom of the PVC pipes every 6 m (19.69 ft) if you route cables by using PVC pipes.

· Seal the holes for routing cables in the wall with waterproof and flame retardant material.
