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

Sheet metal mounting bracket
Screws
Adjustable buckle
Expansion screws
Quick start guide
Warranty card
MAC address label
SN label
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
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 APand the wall. Figure 2-2 shows space requirements.
Figure 2-2 MountinganAP
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 theAP 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.
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 intoAPs, the deployment distance requirements on the antennas are those on
APs.
2.5 Installing an IoT Card
TheAP provides an IoT slot for installing an ANT or RFID card based on customer
requirements.
1. Hold the buckle on the bottom cover of the AP, and remove the cover and plastic plugs.
The number of rubber plugs to be removed depends on the number of radio cables.
Use a flat-head screwdriver to remove the cover. Insert the flat-head screwdriver under the cover buckle
and lever the buckle.

2. Place an IoT card in the slot and tighten the card using M2.5x6 screws (with a tightening
torque of 0.3 Nm).
1. AP
2. IoT card
3. M2.5x6 screws
3. Connect an IoT antenna with the MMCX connector of an IoT card, and slide the IoT
card cover to secure the IoT card. When installing the IoT card cover, insert the
protrusion on the cover into the opening on the AP. Then press the protrusion until you
hear a click sound.
The diagonal size of a hexagon SMAconnector must be less than or equal to 8 mm; otherwise, the
cable cannot be installed.
The ANT card has one radio port, and the RFID card has two.

2.6 Installing the AP
2.6.1 Installing the Device on a Wall
Awall for installing the device needs to meet the following requirements:
The wall can bear the weight of four times the total weight of the device and mounting bracket
without damage.
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 theAP 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. 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 2.7 Cable Connection.
5. Align the rubber feet of the device over the mounting slots on the mounting bracket and
vertically push the AP to secure it. When the spring clip is popped up, push the AP
downward until it snaps into place (you can hear a click).
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.
