2.4 Determining the Installation Position

Indoor APs are usually mounted on a wall or ceiling using sheet metal mounting brackets. The installation position is determined by the site survey. There must be at least 200 mm clearance between the cabling end of the AP and the wall. Figure 2-2 shows space requirements.

Figure 2-2 Mounting an AP

2 AP Installation

When determining the AP installation position, comply with the following rules:

l Try to reduce the number of obstacles, such as walls, between the AP and user terminals.

l Place the AP far away from electronic devices that may produce radio interference, such

as microwave ovens, other APs, antennas, and other radio communication devices. For

Issue 01 (2016-04-15) Huawei Proprietary and Confidential

details, see Table 2-2.

l Install the AP in a hidden position that does not affect daily lives and work of residents.

l Install the AP in a site that is free from leaking or dripping water, heavy dew, and

humidity, and take protective measures to prevent water from flowing into the equipment along the cable.

l Do not install the AP in an environment with high temperature, dust, poisonous gases,

flammable or explosive objects, electromagnetic interference (from a radar station, radio station, or substation), unstable voltage, violent shakes, or strong noise.

Table 2-2 General anti-interference requirements

Scenario Deployment Distance Requirement

2 AP Installation

Indoor installation

NOTE

If antennas are embedded into APs, the deployment distance requirements on the antennas are those on APs.

l There should be at least a 7 m distance between antennas.

l The antennas should be placed at least 2 m from the 4G antennas of

the carrier.

l The antennas should be placed far away from electronic devices that

may produce interference, such as microwave ovens.

2.5 Installing the AP

NOTE

Remove the protective film on the surface before installation to prevent electrostatic discharge.

2.5.1 Installing the Device on a Wall

Mounting APs on a wall requires sheet metal mounting brackets and expansion screws. The procedures are as follows:

1. Fix a mounting bracket against the wall and mark the drilling positions through holes of the bracket.

2. Use a 6 mm drill bit to drill 25 mm to 30 mm deep holes in the drilling positions. Hammer the expansion tubes into the holes until the expansion tubes are completely embedded into the wall.

Issue 01 (2016-04-15) Huawei Proprietary and Confidential

AP7050DE Hardware Installation and Maintenance Guide

3. Fix the mounting bracket to the wall and use the Phillips screwdriver to fasten three expansion screws into the expansion tubes.

4. Connect the cables. For details, see 2.6 Cable Connection.

5. Align the mounting screws at the rear of the AP with the mounting holes on the sheet metal mounting bracket and then press the AP downwards to secure the AP on the bracket.

2 AP Installation

2.5.2 Installing the Device on a Ceiling

1. Remove a ceiling tile, determine locations of mounting holes based on the distance between two installation holes on the mounting bracket, use a hammer drill to drill holes on the ceiling tile, and fix the mounting bracket to the ceiling tile.

The screws provided for ceiling-mounting of APs are 30 mm long and can be used to fix an AP on a ceiling not thicker than 15 mm. To install APs on thicker ceilings, you need to purchase longer screws.

2. Connect the cables. For details, see 2.6 Cable Connection.

3. Hang the AP on the mounting holes by aligning the mounting screws at the rear of the AP with the mounting holes on the bracket and push the AP horizontally to secure the AP.

2 AP Installation

NOTE

Ensure that the AP is correctly installed on the mounting bracket and there must be 200 mm space above and around the AP for maintenance.

2.5.3 Installing the Device on a T-rail

1. Remove two ceiling tiles around the T-rail, use screws to fix the adjustable buckle to the mounting bracket, hook the adjustable buckle to the T-rail, and secure the screw on the adjustable buckle to fasten the mounting bracket and T-rail.

Issue 01 (2016-04-15) Huawei Proprietary and Confidential

AP7050DE Hardware Installation and Maintenance Guide

2. Connect the cables. For details, see 2.6 Cable Connection.

3. Hang the AP on the mounting holes by aligning the mounting screws at the rear of the AP with the mounting holes on the bracket and push the AP horizontally to secure the AP.

2 AP Installation

NOTE

l Before fixing the adjustable buckle with a screw, you need to adjust the buckle to a proper position

based on the T-rail width.

l Ensure that the AP is correctly installed on the mounting bracket and there must be 200 mm space

above and around the AP for maintenance.

Cable or Device Description

1 USB flash drive Connects to a USB flash drive to extend the storage space

of the AP. The USB2.0 standard is supported.

2 Ground cable Connects the AP to the ground.

3 Network cable

l CAT5E cables or higher must be used.

l The service network cable cannot be connected to the

console port; otherwise, the AP may be damaged when using PoE power supply. The network cable length cannot exceed 100 m.

l If the AP needs to connect to the Ethernet, ensure that

the Ethernet cable is working properly. If the Ethernet cable is not working properly, for example, RJ45 connectors are short-circuited, the AP may fail to be powered on or fail to work. Before connecting an Ethernet cable to the AP, use the cable test tool to check whether the cable is qualified. If the cable is unqualified, replace it.

4 DC power adapter When the AP uses the DC power supply, use a power

adapter for power supply; otherwise, the AP may be damaged.

NOTE

The AP is powered by either the DC power supply or PoE power supply that backs up each other.

Pay attention to the following points when bundling the cables:

Issue 01 (2016-04-15) Huawei Proprietary and Confidential

AP7050DE Hardware Installation and Maintenance Guide

l Different types of cables must be separately routed with the minimum spacing of 30 mm

and cannot be entangled or crossed. Cables should be parallel or separated using dedicated separators.

l Bundled cables are closely arranged, straight, tidy, and undamaged.

l Cable ties are bound neatly facing the same direction, and those at the same horizontal

line must be in a straight line. Cable tie tails should be cut smoothly and evenly.

l Labels or nameplates must be attached to the cables after they are installed.

Connecting USB Flash Drivers

To ensure compatibility between USB flash drives and devices, use Huawei-certified USB flash drives (listed in Table 2-4) to configure the Huawei devices.

Connecting the Ground Cable

Use ground screws and ground cables to ground the AP. The ground cables need to be prepared on site. The M6 OT terminal is used to connect to the AP and M8 OT terminals to the ground bar. The type of OT terminals can also be determined according to site surveys. Cut the cable into the required length according to site conditions.

Tighten the OT terminal for the AP with a torque of 3 N•m. The tightening torque for the ground bar varies according to the OT terminals used.

Ground cable deployment requirements are as follows:

l The ground cables must be connected to a group of ground bars.

l The bend radius of the ground cables must be larger than or equal to five times the cable

diameter.

l The ground cables must be buried underground or routed indoors and cannot be led into

the equipment room aerially.

l Both ends of the external conductor of the coaxial cable and those of the shield layer of

the shielded cable should have good electric contact with the metal shell of the equipment they connect to.

l Ground cables must be separated from signal cables to reduce interference between

them.

l Do not add any switch or fuse on the ground cable.

2 AP Installation

l Do not use another device for an electrical connection with the ground cable.

l All metal components in the shell must be securely connected to the ground terminal.

2.7 Connecting the Security Lock

There is a security slot on the device. You can lock the device to an immovable object to prevent theft. The detailed procedures are as follows:

1. Fasten the cable of the security lock to an immovable object around.

2. Insert the security lock into the security slot and lock it.

NOTE

You need to purchase the security lock separately.
