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 moisture, 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

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.

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 6 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 6 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 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 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 installed high 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:

For optimal radio coverage, use professional technical engineers to install the AP as a best practice.

Pre-installation tasks

Before installing an AP, perform the following tasks:

· Connect the AP to a power source and the network. Examine the LEDs to verify that the AP can operate correctly. For more information about the AP LEDs, see "Appendix B LEDs and Ports."

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

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

Before installing the AP, read the following restrictions and 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. Make sure the installation height and location of the AP meet the requirements.

· 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 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.

· When you route PVC pipes outdoors in a horizontal way, cut an opening at the bottom of the PVC pipes every 6 m (19.69 ft) to avoid water accumulation.

· When routing cables outdoors without using cable casings, create drip loops on the cables to prevent the rainwater from flowing into the Ethernet ports of the device along the cables.

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

Connecting cables

CAUTION:

To avoid device damage, install weatherproof caps securely for unused ports.

IMPORTANT:

When you apply weatherproof tape to a cable connection, follow these restrictions and guidelines:

· Make sure you attach the adhesive side of the tape to the cable connector.

· Pull the tape as needed for overlap.

· Start wrapping at the top of the connector, and overlap the tape to half-width. Avoid creases or wrinkles and press the tape against the connection so that there are no gaps. Smooth each wrapped layer with your hands to ensure full adhesion.

Connecting an Ethernet cable

Use Category-5e or above Ethernet cables only. As a best practice, use shielded twisted pair (STP) cables.

To connect an Ethernet cable:

1. Disassemble the liquid-tight adapter and put the rubber seal aside, and then feed the cable through the adapter.

2. Attach the rubber seal to the cable, connect the Ethernet cable to the target port on the AP, and insert the rubber seal into the liquid-tight adapter.

3. Use a wrench or wear nonslip gloves to fasten the sealing nut and the liquid-tight adapter.

Figure2-4 Connecting an Ethernet cable

4. Start wrapping at the top of the connector. Smooth the tape edges to ensure full adhesion.

Figure2-5 Wrapping the connector

5. Route the cable outdoors.

¡ If you route the cable outdoors by using PVC pipes, cut an opening at the bottom of the PVC pipes every 6 m (19.69 ft) to avoid water accumulation.

¡ If you route the cable outdoors without using cable casings, create drip loops on the cable to prevent rainwater from flowing into the Ethernet port of the device along the cable.

Figure2-6 Creating a drip loop

Connecting an optical fiber

Restrictions and guidelines

When you connect an optical fiber, follow these restrictions and guidelines:

· Before connecting an optical fiber, remove the dust caps from the fiber connectors and keep the caps secure.

· To avoid optical fiber damage, do not pull the optical fiber with excessive force.

· To avoid affecting fiber performance, make sure the optical fiber is not bended or folded when fastening the sealing nut.

· To use a fiber pigtail that does not have any protective sleeve, first use weatherproof tape to wrap the fiber pigtail before you connect the fiber pigtail.

Procedure

1. Use weatherproof tape to wrap the fiber connectors around the rubber boots, build up the optical fiber diameter near the opening in the split sealing washer. Smooth the tape edges to ensure full adhesion.

Figure2-7 Wrapping the rubber boots of the fiber connectors

2. Disassemble the liquid tight adapter (assembled by a weatherproof connector, a sealing nut, and a rubber seal) and detach the rubber seal, feed the optical fiber through the connector, and then attach the rubber seal to the cable.

Figure2-8 Feeding the optical fiber through the connector

3. Insert the rubber seal into the weatherproof connector.

Figure2-9 Inserting the rubber seal into the weatherproof connector

4. Adjust the weatherproof connector to ensure that the rubber boots of optical fiber reaches out of the weatherproof connector. Attach a transceiver module to the SFP port of the AP, and then connect the optical fiber to the transceiver module.

Connecting an RF cable

IMPORTANT:

As a best practice, purchase and install lightning arresters for antenna ports in the areas where thunderstorms frequently occur.

CAUTION:

To avoid device damage or bodily injury caused by excessive radiation exposure, make sure the antennas and RF cables comply with local regulations. As a best practice, purchase H3C recommended antennas and RF cables. To enure correct operatison of the AP, make sure the antennas and RF cables meet the following basic requirements:

· The VSWR for RF cables is less than or equal to 1.4.

· The VSWR for antennas is less than or equal to 1.8.

· The maximum gain can ensure that the AP's EIRP complies with local regulations.

You can connect an RF cable or antenna to an antenna connector. The connection procedure is the same. The following procedure connects an RF cable to an antenna connector.

To connect an RF cable:

1. Remove the weatherproof cap from the antenna connector on the AP.

2. Connect a lightning arrester to the antenna connector.

3. Connect the RF cable to the lightning arrester.

4. Wrap each connection with weatherproof tape until the entire connection is wrapped. Smooth the tape edges to ensure full adhesion.
