1.4 Power Sources
The AP can be powered either with a DC power adapter or through Power over Ethernet (PoE).
The AP requires Nodexon power adapters (If needed, you can buy them from
Nodexon). To use a PoE device, make sure it supports the IEEE 802.3af PoE
standard.
1.5 Cooling Solution
The AP adopts fanless design.
Leave sufficient space at the surrounding of the AP when place the AP to permit airflow for proper ventilation.

·
2 Preparing for Installation
To prevent device damage and bodily injury, please read carefully the safety recommendations described in this
chapter.
The recommendations do not cover all possible hazardous situations.
2.1 Installation
The AP must be installed indoors. To ensure its normal operation, the installation site must meet the following
requirements.
Install the AP in a well-ventilated environment. If it is installed in a closed room, make sure there is a good cooling
system.
Make sure the site is sturdy enough to support the AP and its accessories.
Make sure the site has enough space for installing the AP and leave sufficient room around the AP for ventilation.
Also, to avoid mutual interference, ensure the site is at least 2 meters away from a base station antenna.
Do not expose the AP to high temperature, dusts, or harmful gases.
Do not install the AP in an inflammable or explosive environment.
Keep the AP away from EMI sources such as large radar stations, radio stations, and substations.
Do not subject the AP to unstable voltage, vibration, and noises.
Keep the AP at least 500 meters away from the seaside and do not face it toward the wind from the sea.
The installation site should be free from water flooding, seepage, dripping, or condensation.
The installation site shall be selected according to network planning and features of communications equipment, and
considerations such as climate, hydrology, geology, earthquake, electric power, and transportation.
Please follow the correct method described in the installation guide to install and remove the device.
2.2 Movement
Avoid moving the device frequently.
Turn off all power supplies and unplug all power cables before you remove the device.
2.3 EMI
Please observe local regulations and specifications when performing electrical operations. Relevant operators must
be qualified.
Please carefully check for any potential danger in the working area, for example, damp/wet ground or floor.
Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in case of an accident.

·
Be sure to make a careful check before you shut down the power supply.
Do not place the device in a damp/wet location. Do not let any liquid enter the chassis
Keep the AP far away from the grounding or lightning protection devices of power equipment.
Keep the AP away from radio stations, radar stations, high-frequency high-current devices, and microwave ovens.
Any nonstandard and inaccurate electrical operation can cause an accident such as fire or electric shock, thus
causing severe even fatal damages to human bodies and device.
Direct or indirect touch through a wet object on high voltage and power line can bring a fatal danger.
2.4 Ventilation
For proper ventilation, leave sufficient space around the AP.
2.5 Temperature and Humidity
To ensure normal operation and service life of the device, maintain appropriate temperature and humidity levels in your
equipment room. See Table 2-1. Improper room temperature and humidity can cause damages to the device.
High relative humidity may affect insulation materials, resulting in poor insulation and even electrical leakage, and
sometimes may lead to change of mechanical properties of materials and corrosion of metal parts.
Low relative humidity may dry and shrink insulation sheets and cause static electricity that can damage the circuitry
inside the device.
High temperature greatly reduces reliability of the device and shortens its service life.

Temperature
Relative Humidity
-10°C to 50°C (14°F to 122°F)
5% to 95%
2.6 Cleanness
Dust poses a serious threat to device operation. Dust that falls onto the surface of the device can be absorbed onto metal
contact points by static electricity, resulting in poor contact. Electrostatic absorption of dust occurs more easily when the
relative humidity is low, which may shorten the service life of the device and cause communication failures. Table 2-2
shows the maximum concentration and diameter of dust allowed in the equipment room.

Besides, the contents of salts, acids and sulfides in the air are also strictly limited for the equipment room. These
substances can accelerate metal corrosion and the aging of some parts. Table 2-3 describes the limit of some hazardous
gases such as SO2, H2S, NO2and Cl2 in the equipment room.
