Examining the installation site
Before installation, examine the installation site to make sure that the AP will work in a good environment. You can examine the installation site from the following two aspects.
Installation site selection
Keep the AP away from high temperature, dust, harmful gases, inflammables, explosive substances, electromagnetic interference sources (heavy-duty radars, radio stations, or electrical substations), unstable voltage, heavy vibration, or loud noise. The installation site should be dry, without any leakage, dripping, or dew. The AP should be at least 500 m (0.31 miles) away from the seaside and should not face the direction of sea wind.
In engineering design, the site should be selected according to the network planning and technical requirements of the communications equipment, and the considerations such as climate, hydrology, geology, earthquake, electric power, and transportation.

Power supply
The AP can be powered by a power injector or through PoE+.
Power injector
You can use an H3C POE5 power injector to power the AP. For more information about how to power the AP through the power injector, see “Connecting the AP to a power injector.”
|
|
NOTE: The power injector is not shipped with the AP and must be ordered separately. |
PoE+
If the switch connected to the AP is PoE+ capable, the AP can be powered by the switch through the cable between the 10/100/1000BASE-TX port of the AP and the Ethernet port of the switch.
Grounding and lightning protection
Table 6 Grounding and lightning protection requirements
|
Item |
Requirements |
|
Grounding resistance |
· The grounding resistance is usually required to be less than 5 ohms, and less than 10 ohms in an area with less than 20 thunderstorm days a year. If a piece of angle steel is buried as the grounding conductor, the grounding resistance is required to be less than 10 ohms. In an area with a higher grounding resistance, reduce the grounding resistance by using brine or resistance reducing agent around the grounding conductor. · The top of the grounding conductor should be at least 0.7 m (2.30 ft) away from the ground surface. In cold areas, the grounding conductor should be buried below the frozen soil layer. |
|
Grounding connection |
· If a grounding strip is available, connect the yellow and green grounding cable of the AP to the grounding strip. To make a grounding cable, make sure the cable is with a cross-section area of at least 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 at least 0.5 m (1.64 ft) long in the earth to serve as the grounding conductor. In the case of a piece of angle steel, the size should be at least 50 × 50 × 5 mm (1.97. × 1.97 × 0.20 in); in the case of a piece of steel tube, it must be zinc-plated and have a wall thickness of at least 3.5 mm (0.14 in). Weld the yellow and green grounding cable of the AP onto the grounding conductor and use anti-erosion treatment on the welding joint. The grounding cable should be as short as possible and must not be coiled. · Make sure that the grounding terminals of all the lightning arresters of the AP and the peer device of the AP are well grounded. |
|
Grounding lead-in |
A grounding lead-in is a metal conductor connecting a grounding net and a grounding strip. The grounding cable of the AP should be connected to the grounding strip. The grounding lead-in 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 grounding lead-in 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 should not be connected with the PGND of other communications equipment. The L and N lines cannot be connected. |
|
Lightning rod |
In plain areas, the shielding angle of the lightning rod should be less than 45 degrees. In mountainous areas or lightning areas, the shielding angle should be less than 30 degrees. The lightning protection grounding (for example, the grounding of the lightning rod) should be connected to the grounding conductor of the equipment room. |
|
Antenna |
· The antenna support is already prepared according to the design requirements. · The AP is well grounded according to design requirements. |
|
Network cable |
Use a shielded twisted pair cable for outdoor installation. Make sure that the devices at the two ends of the cable are well grounded. |
Examining the AP
Before installing the AP, supply power to the AP, connect the AP to the Ethernet, and check the status of the LEDs to make sure that the AP is functional. Save the MAC address of the AP for future use.
The WA2620X-AGNP AP can be mounted on a pole. To ensure the radio coverage, have the AP installed by professionals.
Installing the AP
|
|
CAUTION: To install the AP and antennas on the same pole, the outer diameter of the pole must be between 60 mm and 70 mm (2.36 in and 2.76 in). |
The AP can be fixed to a pole whose outer diameter is between 60 mm and 110 mm (2.36 in and 4.33 in). The mounting kit includes a pair of V-shaped brackets, a mounting plate, bolts, and nuts. See Figure 4.

4. Fix the AP onto the mounting plate with screws and fasten the screws. See Figure 7.
|
|
NOTE: You can fix the mounting plate on the pole with brackets before or after fixing the AP onto the mounting plate, whichever is more convenient. |
Installing the outdoor antennas
Outdoor antennas fall into directional and omnidirectional antennas. Omnidirectional antennas can be installed on the AP directly. The following section describes how to install directional and omnidirectional antennas.
Installing a directional antenna on a pole
|
|
NOTE: Make sure that the location of the pole does not hamper the adjustment of antenna direction and tilt. |
Before you install a directional antenna on the pole, make sure that the pole is vertical to the rooftop surface.
To install a directional antenna:
1. Weld the lightning rod to the tip of the pole.
2. Install the pole on a parapet or cement pier.
? If there are parapets on the rooftop and the height of the parapets is no less than 1.2 m (3.94 ft), you can fix the pole on a parapet with expansion screws and fix the directional antenna on the pole with the pole mounting bracket. See Figure 8.
Figure 8 Install a directional antenna on a parapet (I)
? If there are parapets on the rooftop and the height of the parapets is less than 1.2 m (3.94 ft), you can fix the pole on a parapet at one point with expansion screws and fix the bottom end of the pole to the rooftop surface, and then fix the directional antenna on the pole with the pole mounting bracket, as shown in Figure 9.
Figure 9 Install a directional antenna on a parapet (II)
? If there is no parapet on the rooftop, fix the pole to the rooftop surface or a cement pier on the rooftop with expansion screws and stabilize the pole with steel wires. Then, install the directional antenna on the pole, as shown in Figure 10.
Figure 10 Install a directional antenna on a cement pier
3. Connect the pole to a grounding grid with a flat steel bar (40 x 4 mm or 1.57 x 0.16 in).
4. Fix the antenna on the pole with the pole mounting bracket.
Installing the omnidirectional antennas on poles
|
|
NOTE: · The diameter of the poles for omnidirectional antennas must be 50 mm to 70 mm (1.97 in to 2.76 in). Usually, poles are made of round steel bars 50 mm (1.97 in) in diameter. · The pole clamp at the top of the pole and the one at the bottom of the antenna must be level, as shown in Figure 11. · The antennas and the lightning rod must be of such heights that the antennas can provide desired coverage and remain within the shielding angle (45°) of the lightning rod. |
Omnidirectional antennas must be kept at least one meter (3.28 ft) away horizontally from metal objects. Therefore, do not weld the lightning rod on a pole attached with an antenna. Install the lightning rod on a separate pole between the two omnidirectional antennas and ensure that the antennas are within the shielding angle of the lightning rod.
Figure 11 Install omnidirectional antennas
If separately installing the lightning rod is not practical, use the alternative method shown in Figure 12, but allow at least one meter (3.28 ft) of clearance between the lightning rod and the antenna.
Figure 12 Alternative method for installing an omnidirectional antenna
|
|
NOTE: In Figure 12, the antenna pole is not fixed on the cement pier. Instead, the antenna pole is fixed by welding two angle steel bars between the antenna pole and the lightning rod pole. |
Connecting cables
|
|
WARNING! Before connecting any cable, make sure that all power lines are disconnected and locked out and that no hazardous voltage is present on the neutral (N) line. |
|
|
CAUTION: Make sure that the outer sheath of cables is intact and does not absorb moisture to protect the AP from water leak. |
External cables may include antenna cable, Ethernet cable, fiber cable, grounding cable, and power cord.
Connecting the antenna cables
The antenna cables connect the antenna ports (2.4 GHz and 5 GHz) to the outdoor antennas.
To connect the antenna cables:
1. Connect the antenna cables to the antenna ports of the AP at one end and to the outdoor antennas at the other end.
? For 2 x 2 MIMO antennas, connect the cables to the 2.4 G-1/3 and 5G-1/3 antenna ports on the AP.
? For 3 x 3 MIMO antennas, connect the cables to the 2.4 G-1/2/3 and 5G-1/2/3 antenna ports on the AP, respectively.
2. Wrap the connections with insulating tape and apply several layers of waterproof sealing tape over the insulating tape.
|
|
NOTE: · No antenna arrestor is needed. The WA2620X-AGNP AP provides lightning arresting function. · Make sure that the grounding cables are well grounded during outdoor deployment. · You have the option to order the standard ready-made antenna cables, or order cables of desired lengths and N-type antenna connectors and make antenna cables on-site as needed. · Stretch the waterproof sealing tape till the width of the tape is reduced to 3/4 of the original width and wrap the waterproof sealing tape around the cable to achieve desired waterproof performance. |
Connecting the Ethernet cable
|
|
CAUTION: Observe the following procedure when connecting the copper cable. Otherwise, the AP might be damaged. |
1. Route the Ethernet cable with waterproof sheath from the equipment room to the AP.

3. Make sure the sealing nut is loose. Tighten the liquid tight adapter, and then tighten the sealing nut.
4. Seal the connection with waterproof sealing tape.
|
|
NOTE: · The optional fiber cable is a 10-meter pigtail with waterproof sheath. One end of the pigtail uses an LC connector and a liquid tight adapter and is inserted into the fiber port of the AP and the other end uses an SC connector and is connected to an end user terminal or switch. · If the fiber is connected to a fiber termination box, connect the SC connector to a pair of SC sockets. The one marked as A is the receiving port (RX) of the AP and must be connected to the transmitting port (TX) of the peer device; the one marked as B is the TX port of the AP and must be connected to the RX port of the peer device. Usually, fiber termination boxes are not waterproof. Put the fiber termination box indoor or in a waterproof cabinet. · If the fiber is connected to a fiber connector box, cut off the SC connector and splice the fiber end with the connector on the connector box. The pigtail marked as A is connected to the RX port of the AP and the TX port of the peer device; the pigtail marked as B is connected to the TX port of the AP and the RX port of the peer device. Fiber connector boxes are usually waterproof and can be buried underground or mounted on a pole. |
Connecting the AP to the power source
The WA2620X-AGNP AP can be powered by a power injector or a PoE+ switch.
Connecting the AP to a power injector
To connect the power injector to the AP (see Figure 15):
1. Connect the power input line to an AC power source.
2. Connect the signal & power output line to the copper port of the AP.
3. Connect the signal input line to a switch or an access controller.
4. Ground the grounding terminal of the power injector.
Connecting the AP to a PoE+ capable switch
To power the AP by using a PoE+ capable switch, connect the 10/100/1000BASE-TX port of the AP to an Ethernet port of the switch through an Ethernet cable.
|
|
NOTE: · If the AP is powered by a PoE+ switch, the power injector is not needed. Make sure that the PoE+ port can support the maximum power consumption of the AP. · If the AP is powered by a power injector, put the power injector at the switch side, and the switch connected to the power injector does not need to be PoE+ capable. · Make sure that the installation of the AP is complete before powering on the AP, regardless of whether the AP is powered through PoE+ or by a power injector. |
Connecting the grounding cable
Connect the grounding terminal of the AP to the grounding point with the yellow and green grounding cable shipped with the AP, as shown in Figure 3. For more information about the procedure, see “Grounding and lightning protection”.
|
|
NOTE: If the AP is powered by a power injector, the grounding terminal of the power injector must also be grounded. |
Verifying the installation
After the installation and cabling, check the following items before powering on the AP:
· The power source meets the power specification of the AP;
· The AP is well grounded;
· The Ethernet cables are correctly connected;
· The outdoor antennas are installed;
