NOTE

If a PoE adapter or a DC power adapter is required, you need to purchase it separately. For DC power adapter models, see 5.9 Power Adaptation Solution.

2.4 Determining the Installation Position

2 AP Installation

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

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.

Issue 05 (2018-02-02) Huawei Proprietary and Confidential

AP4050DN-E Hardware Installation and Maintenance Guide

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 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

2 AP Installation

Scenario

Indoor installation

NOTE

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

Deployment Distance Requirement

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

l The antennas should be placed at least 5 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 an IoT Card

An AP4050DN-E has three IoT slots supporting ANT and RFID cards. An ANT card has only one radio port while an RFID card has two radio ports. Depending on card characteristics, IoT cards can be installed in one-cable per card or two-cable per card mode. Users need to install IoT cards onsite as required.

One-Cable per Card

In this mode, one to three ANT or RFID cards can be installed.

1. Remove the front cover of an AP.

Rubber plugs

AP4050DN-E Hardware Installation and Maintenance Guide

2. Remove rubber plugs based on the number of IoT cards to be installed. One rubber plug maps one IoT card.

2 AP Installation

3. Place IoT cards in the slots and tighten the cards using M2x7 screws (with a tightening torque of 1.5 N•m). You are advised to start installation from the card1 slot.

NOTE

A wall for installing the device needs to meet the following requirements:

l The wall can bear the weight of four times the total weight of the device and mounting bracket

without damage.

l When the tightening torx of a screw reaches 5 N•m, the screw still properly works, without crack

or damage on the wall.

Mounting kits and expansion bolts are required to install the AP on a wall. The procedures are as follows:

When fixing the sheet metal mounting bracket, ensure that the arrows point upwards on the

label.

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

2 AP Installation

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.

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

NOTE

In a scenario with heavy vibrations, tighten the AP to the mounting bracket using M4x30 screws with a torque of 1.4N•m. This prevents the AP falling off from due to vibrations. In normal scenarios, you do not need to install these screws.

2 AP Installation

2.6.2 Installing the Device on a Ceiling

NOTE

A ceiling needs to bear the weight of four times the total weight of the device and mounting bracket without damage.

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(with a tightening torque of 1.4 N•m).

The screws provided for ceiling-mounting of APs are 30 mm long and can be used to fix an AP on a ceiling no thicker than 15 mm. To install APs on thicker ceilings, you need to purchase longer screws.

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

and around the AP for maintenance.

l In a scenario with heavy vibrations, tighten the AP to the mounting bracket using M4x30 screws

with a torque of 1.4N•m. This prevents the AP falling off from due to vibrations. In normal scenarios, you do not need to install these screws.

2.6.3 Installing the Device on a T-rail

A T-rail needs to bear the weight of four times the total weight of the device and mounting bracket without damage. Figure 2-3 shows the T-rail dimensions requirements (t: thickness; w: width).

NOTE

l Before fixing the adjustable buckle with a screw, 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 is 200 mm space above

and around the AP for maintenance.

l In a scenario with heavy vibrations, tighten the AP to the mounting bracket using M4x30 screws

with a torque of 1.4N•m. This prevents the AP falling off from due to vibrations. In normal scenarios, you do not need to install these screws.

2.6.4 Removing an AP

Flip the spring clip on the mounting bracket and slip the AP towards the spring clip. Release the spring clip until the rubber feet of the AP enter the mounting keyholes. Remove the AP from the mounting bracket.

Figure 2-4 Removing an AP

NOTE

If a captive screw is installed, remove the screw and then follow the preceding steps to uninstall the AP.

2 AP Installation

2 Network cable

l The service network cable and PoE input cable cannot

be connected to the console port. Otherwise, the AP may be damaged when using PoE power supply.

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.

NOTICE

l Do not insert a PoE input cable into the GE1/PoE_OUT port.

l CAT5e cables or higher must be used.

l The length of a cable in the GE0/PoE_IN interface cannot

exceed 100 m.

l The length of a cable cannot exceed 40 m when the GE1/

PoE_OUT port has PoE output and cannot exceed 100 m when there is no PoE output.

l The GE1/PoE_OUT port of an AP can provide power output

only works in 802.3at PoE mode. The output power varies at different connection status:

l The maximum output power is 7 W when no IoT card is

connected to the AP and the USB port is not used.

l The maximum output power is 5.5 W when only one IoT

card is connected to the AP and the USB port is not used.

l The PoE_OUT function is automatically disabled when

two or more IoT cards are connected to the AP or the USB port is used.

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

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

4 RF cable Connects to an IoT card or an antenna.

NOTE

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

When installing a cable, you must make a drip loop to prevent water from flowing into devices along the cable. For the method of making the drip loop, see 5.8 Guide to Making

Drip Loops.

Pay attention to the following points when bundling the cables:

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.
