2.3 Unpacking the Equipment
Before unpacking the carton, ensure that the packing carton is intact and not damaged or
soaked. Stop unpacking if the equipment is rusted or soggy. Then, investigate causes and
contact the supplier.
After unpacking, check items in the carton against the packing list. If any item is missing,
contact the supplier or agent.
Usually, the packing list contains the following items.
AP device
Indoor fixed sheet metal mounting bracket
DC power adapter (optional)
Screw
Adjustable buckle
Hose clamp (optional)
Expansion screws

MAC address label
SN label
If a PoE adapter is required, you need to purchase it separately.
If a PoE adapter is required, you need to purchase it separately.
The angle-adjustable mounting kits need to be purchased separately.
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
When determining the AP installation position, comply with the following rules:
Try to reduce the number of obstacles, such as walls, between the AP and user terminals.
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.
Install the AP in a hidden position that does not affect daily lives and work of residents.

AP4050DN-HD
Hardware Installation and Maintenance Guide 2 AP Installation
Issue 01 (2016-04-15) Huawei Proprietary and Confidential

10
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.
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
Indoor
installation
There should be at least a 7 m distance between antennas.
The antennas should be placed at least 2 m from the 4G antennas of
the carrier.
The antennas should be placed far away from electronic devices that
may produce interference, such as microwave ovens.
If antennas are embedded into APs, the deployment distance requirements on the antennas are those on
APs.
2.5 Installing the AP
Remove the protective film on the surface before installation to prevent electrostatic discharge.
2.5.1 Installing the Device on a Wall
Mounting kits and expansion bolts are required to install the AP on a wall. The
AP4050DN-HD can be installed on a wall using an indoor fixed or angle-adjustable mounting
bracket.
The indoor fixed mounting bracket is delivered together with the AP, but the angle-adjustable mounting
bracket is optional and needs to be purchased separately.
Indoor Fixed Mounting Bracket
1. Fix the mounting bracket to the wall, adjust the installation position, and use the marker
to mark the drilling positions where expansion screws are installed.

11
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.
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.

12
Angle-Adjustable Mounting Bracket
1. Place a base bracket against the wall and mark the drilling positions through holes of the
bracket, as shown in the following figure.
2. Use an 8 mm drill bit to drill 35 mm to 40 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. Place the base bracket against the wall and use a wrench to fasten two expansion screws
into the expansion tubes.
4. Remove the topmost screw from the base bracket, hang the AP-side mounting bracket
onto the topmost screw, and tighten the screw until the screw passes through the hole of
the horizontal scale plate.
5. Connect the cables. For details, see 2.6 Cable Connection.
6. Align the mounting screws at the rear of the AP with the mounting holes on the bracket
and hang the AP on the bracket. Push the AP downward to secure the AP.
7. Loosen the two screws at the horizontal direction, adjust the AP's angle at the horizontal
and vertical directions, and tighten the hex socket screws. Use M4x35 cruciform slot
screws to tighten the AP and mounting bracket from the side.

The angle-adjustable mounting bracket can adjust the AP's angle within ±60° at the vertical and
horizontal directions.
2.5.2 Installing the Device on a Ceiling
The AP4050DN-HD can be installed on a ceiling using an indoor fixed or angle-adjustable
mounting bracket.
Indoor Fixed Mounting Bracket
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.
1. Ceiling tile 2. Adjustable buckle 3. M4x30 screw
2. Connect the cables. For details, see 2.6 Cable Connection.
