Hardware Installation and Reference Guide Product Introduction

1 Product Introduction

RG-AP820(AR) is an IEEE 802.11ax-compliant AR series wireless access point (AP) released by Ruijie

Networks for indoor high-density scenarios in the higher education, government, general education, finance,

and business sectors.

The RG-AP820(AR) complies with the IEEE 802.11ax, 802.11ac Wave 2, 802.11ac Wave 1, and 802.11n

protocols. It adopts the tri-radio design and can provide a maximum wireless access rate of 3.267 Gbps, which

breaks through the bottleneck in wireless performance.

The RG-AP820(AR) integrates Ruijie's exclusive AI Radio design. The extra intelligent radio card provides better

access experience and real-time full-band security protection for users in the Wi-Fi 6 environment.

Important factors such as the wireless network security, radio control, mobile access, Quality of Service (QoS),

seamless roaming, and expansion of the Internet of Things (IoT) module are fully taken into account for the RG-

AP820(AR). Therefore, this AP can be used together with Ruijie's access controllers (ACs) and WIS to

implement STA data forwarding, security, access control, and IoT application extension.

Moreover, the RG-AP820(AR) supports local power supply and power over Ethernet (PoE), which can be

selected based on power supply conditions. In addition, this AP can be mounted onto a wall or ceiling, making

the AP especially applicable to large campuses, conference centers, plazas, or other densely populated

scenarios.

(For details about the adapter specifications, see Section 2.2.5 and Appendix C.)

To power the RG-AP820(AR) by using PoE+, ensure that the device at the other end of the Ethernet cable

supports IEEE 802.3at power supply.

Heat Dissipation Solution

The RG-AP820(AR) adopts the fan-free design.

Caution

Hardware Installation and Reference Guide Preparing for Installation

2 Preparing for Installation

2.1 Safety Precautions

Caution

To avoid personal injury and device damage, carefully read the safety precautions before you install the AP.

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.

Keep the site where the AP is installed dry, so it is not recommended to install the AP near the ocean. Keep

the AP at least 500 meters away from the ocean and do not face it towards the sea breeze.

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.

Caution

Install and remove the AP properly by following instructions in the installation guide.

2.1.2 Handling Safety

Pay attention to the following points when moving the AP:

Do not frequently move theAP after the AP is installed.

Cut off all the power supplies and unplug all power cords before moving or handling the AP.

2.1.3 Electric Safety

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 power supply is

grounded, whether the grounding is reliable, and 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.

Confirm the preceding items when you cut off the power supply.

Do not place the device in a wet position, and keep the device away from liquid.

Keep the AP far away from grounding or lightning protection devices for power equipment.

Keep the AP away from radio stations, radar stations, high-frequency high-current devices, and microwave

ovens.

Hardware Installation and Reference Guide Preparing for Installation

Caution

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 through wet objects may cause fatal

dangers.

2.2 Installation Environment Requirements

The RG-AP820(AR) must be used indoors. Install theAP indoors to ensure its normal operation and prolong the

service life. The installation site must meet the following requirements.

2.2.1 Installation Requirements

Install the AP in an open environment. If the AP is installed in a closed environment, ensure that the

environment has proper ventilation and heat dissipation.

Ensure that the installation location is sturdy enough to support the weight of theAP and its accessories.

Ensure that the dimensions of the installation location for the AP are proper with sufficient clearance around

the AP for heat dissipation. The installation location must be at least 2 m away from base station antennas

to prevent mutual interference.

2.2.2 Ventilation Requirements

Reserve sufficient clearance around the AP for heat dissipation when installing the AP, because the AP adopts

a fan-free design.

2.2.3 Temperature and Humidity Requirements

To ensure the normal operation and prolonged service life of the AP, maintain an appropriate temperature and

humidity in the equipment room. An equipment room with too high or too low temperature and humidity for a

long period may damage the device.

In an environment with high humidity, the insulating material may have poor insulation or even leak electricity.

Sometimes it is also prone to changes in the mechanical properties and causes rusting of metal parts.

In an environment with low relative humidity, the insulating strip may dry and shrink, static electricity may

occur and damage the internal circuits of the AP.

Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the

AP and severely affecting its service life.

The following table describes the temperature and humidity requirements for the RG-AP820(AR).

Operating Temperature

Operating Humidity

–10ºC to +50ºC (14°F to 122°F)

5% to 95%

2.2.4 Cleanliness Requirements

Dust poses a major threat to the AP. Indoor dust falling on the device may be adhered by static electricity,

causing poor contact of metallic joints. Such electrostatic adhesion may occur more easily when the relative

humidity is low, not only affecting the service life of the AP, but also causing communication faults. The following

table describes the requirements for the dust content and granularity in the equipment room.
