Product Introduction
1 Product Introduction
1.1 Overview
RG-AP850-AR(V3) is an IEEE 802.11ax-compliant wireless access point (AP) released by Ruijie Networks for
indoor scenarios in the higher education, government, general education, finance, and business sectors. It
supports four radios, among which the 2.4 GHz band can provide a maximum data rate of 574 Mbps and the 5
GHz band can provide a maximum data rate of up to 4.8 Gbps. This AP can provide a maximum access rate of
5.378 Gbps, which breaks through the bottleneck in wireless performance.
In the design of RG-AP850-AR(V3), wireless network security, radio control, mobile access, Quality of Service
(QoS), and seamless roaming, IoT module expansion, and other important factors are fully considered. The RG-
AP850-AR(V3) can be used together with Ruijie's access controllers (ACs) to implement STA data forwarding,
security, and access control.
The RG-AP850-AR(V3) can work in IEEE 802.11ax, 802.11ac, and 802.11n modes simultaneously. It can be
mounted onto a wall, ceiling, and other locations. Moreover, the RG-AP850-AR(V3) supports local power supply
and power over Ethernet (PoE), which can be selected based on power supply conditions. It is especially
applicable to large campuses, enterprise offices, hotspots, and other high-density scenarios.
1.2 Product Appearance
The RG-AP850-AR(V3) provides three RF ports, two Ethernet copper ports, one 5G SFPport, one RJ45 console
port, one DC power connector, one USB port, and one reset button. For the two Ethernet copper ports, LAN 1
port supports IEEE 802.3af/at/bt-compliant PoE and LAN 2/IoT port can be used to supply power to the IoT
module (48 V/0.27 A, Max.: 12.95 W). The following figures show the product appearance.

Caution
To power the AP by using PoE, ensure that the device at the other end of the Ethernet cable supports
IEEE 802.3af power supply.
The AP adopts the fan-free design. Therefore, maintain sufficient clearance around the AP for air
circulation.
By default, the AP works with IEEE 802.3at power supply. To enable the functions that are available in
IEEE 802.3bt power supply mode, run the related commands.
If IEEE 802.3af power supply is adopted, the AP can be normally powered on, but only one stream is
available for Radio 1 to Radio 3, AI Radio is disabled, and the downlink port and USB port cannot supply
power to external devices.
If IEEE 802.3at power supply is adopted, the AP can be normally powered on, but the downlink port and
USB port cannot supply power to external devices.

Product Introduction
1.6 Optical Module
The peer device connected to the 5 Gbps optical port of the AP should provide an optical or copper port.
However, the two devices may use different optical modules and support different port rates, so the final
negotiated access rate is not fixed. For details, see Table 1-10 and Table 1-11.

Hardware Installation and Reference Guide
Product Introduction
The AP supports an uplink combo port. If both uplink optical port and copper port are connected with
cables, the AP selects the uplink optical port for data transmission (with the uplink copper port
automatically disabled). After the cable of the uplink optical port is disconnected, the uplink copper port is
automatically enabled.

Preparing for Installation
2 Preparing for Installation
2.1 Safety Precautions
Note
To avoid personal injury and device damage, carefully read the safety precautions before you install the
device.
The following safety precautions may not cover all possible dangers.
2.1.1 General Safety Precautions
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 theAP to unstable voltage, vibration, and noises.
The installation site should be free from water flooding, seepage, dripping, or condensation. The installation
site should be selected according to network planning, communications equipment features, and
considerations such as climate, hydrology, geology, earthquake, electrical power, and transportation.
Keep the site where the device is installed dry, so it is recommended not to install the device near the ocean.
Keep the device at least 500 meters away from the ocean and do not face it towards the sea breeze.
Do not place the device in walking areas.
During the installation and maintenance, do not wear loose clothes, ornaments, or any other things that may
be hooked by the chassis.
Keep tools and components away from walking areas.
2.1.2 Handling Safety
Do not frequently move the device.
Cut off all the power supplies and unplug all power cords before moving or handling the device.
2.1.3 Electric Safety
Warning
Improper or incorrect electric operations may cause a fire, electric shock, and other accidents, and lead
to severe and fatal personal injury and device damage.
Direct or indirect contact with high voltage or mains power supply via wet objects may cause fatal
dangers.
Observe local regulations and specifications during electric operations. Only personnel with relevant
qualifications can perform such operations.
Check whether there are potential risks in the work area. For example, check whether the ground is wet.
Find the position of the indoor emergency power switch before installation. Cut off the power switch in case
of accidents.

12
Hardware Installation and Reference Guide
Preparing for Installation
Confirm the preceding items before you cut off the power supply.
Do not place the device in a damp/wet location. Do not let any liquid enter the chassis.
Keep the device far away from grounding or lightning protection devices for power equipment.
Keep the device away from radio stations, radar stations, high-frequency high-current devices, and
microwave ovens.
2.1.4 Storage Safety
For proper working of the AP, the AP must be stored in an environment based on the storage
temperature/humidity requirements in Specifications.
Caution
If the AP is stored for more than 18 months, power on the AP and run it for consecutive 24 hours to activate the
AP.
2.2 Installation Environment Requirements
Install the device indoors to ensure its normal operation and prolonged service life.
The installation site must meet the following requirements.
2.2.1 Bearing Requirements
Evaluate the weight of the device and its accessories (such as the bracket and power supply module), and
ensure that the ground of the installation site meets the requirements.
2.2.2 Ventilation Requirements
Reserve sufficient space in front of the air vents to ensure normal heat dissipation. After various cables are
connected, bundle the cables or place them in the cable management bracket to avoid blocking air inlets.
2.2.3 Space Requirements
Maintain a minimum clearance of 0.4 m (15.75 in.) around the device to ensure proper cooling and ventilation.
2.2.4 Temperature/Humidity Requirements
To ensure the normal operation and prolonged service life of the device, maintain an appropriate temperature
and humidity in the equipment room.
The equipment room with too high or too low temperature and humidity for a long period may damage the device.
In an environment with high relative humidity, the insulating material may have poor insulation or even leak
electricity.
In an environment with low relative humidity, the insulating strip may dry and shrink, loosening screws.
In a dry environment, static electricity is prone to occur and damage the internal circuits of the device.
Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the
device and severely affecting its service life.
