·
Hardware Installation and Reference Guide Preparing for Installation
2Preparing for Installation
To prevent device damage and physical injury, please read the safety recommendations carefully as described in
this chapter.
Recommendations do not cover all possible hazardous situations.
2.1 Installation
The AP must be installed indoors. To ensure 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.
Do not expose the AP to high temperature, dust, or harmful gases.
Do not install the AP in an area prone to fire or explosions.
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 ocean and do not face it towards the sea breeze.
The installation site should be free from water including possible flooding, seepage, dripping, or condensation.
The installation site should be selected according to network planning and communications equipment features, and
considerations such as climate, hydrology, geology, earthquake, electrical power, and transportation.
Please follow the correct method described in the installation guide to install and remove the device.
2.2 Movement
Avoid frequently moving the device.
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.
Carefully check for any potential hazards in the working area such as damp/wet ground or floors.
Find the location of the emergency power supply switch in the room before installation. Cut off the power supply first
in case of an accident.
Be sure to make a careful check before shutting down the power supply.

·
Hardware Installation and Reference Guide Preparing for Installation
Do not place the device in a damp/wet location. Do not let any liquid enter the chassis.
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.
Any nonstandard and inaccurate electrical operation can cause an accident such as fire or electric shock, thus
causing severe even fatal damages to humans and devices.
Direct or indirect contact with a wet object (or your finger) on the high voltage and power line can be fatal.
2.4 Ventilation
For proper ventilation, leave sufficient space around the AP.
2.5 Temperature and Humidity
To ensure the normal operation and equipment service life, maintain appropriate temperature and humidity levels in the
equipment room. See Table 2-1. Improper room temperature and humidity can cause damage to the device.
High relative humidity may affect insulation materials, resulting in poor insulation and even electrical leakage.
Sometimes it may lead to changes in the mechanical properties of materials and corrosion of metal parts.
Low relative humidity can dry and shrink insulation sheets and cause static electricity that can damage the circuitry.
High temperatures greatly reduce device reliability and shorten service life.
Table 2-1 Required Temperature and Humidity for the RG-AP840-I
Temperature
Relative Humidity
-10ºC to 50ºC (14°F to 122°F)
5% to 95%
2.6 Cleanness
Dust poses a serious threat to device operation. Dust on the surface of the device can be absorbed onto metal contact
points by static electricity causing poor contact. Electrostatic absorption of dust occurs more easily when the relative
humidity is low, and might shorten the equipment service life and cause communication failures. Table 2-2 shows the
maximum concentration and diameter of dust allowed in the equipment room.

Maximum concentration
(Particles/m3)

1.3×105
The amount of salt, acids and sulfides in the air are also strictly limited for the equipment room. These substances can
accelerate metal corrosion and aging of some parts. Table 2-3 describes the limits of some hazardous gases such as
SO2, H2S, NO2and Cl2 in the equipment room.

directions (the AP can only slide out in one direction).
Figure 3-11 Removing the Ceiling Mount AP
3.7 Connecting Cables
Connect the UTP/STP to the LAN1/PoE port on the AP. See Appendix A for the supported wiring for twisted pairs.
By default, the baud rate is set to 9600, data bit 8, parity none, stop bits 1 and flow control none on the AP console
port. The console port is used only when you want to configure the AP manually.
Avoid bending the cable in a small radius close to the connector.
Ruijie recommends that you do not use Ethernet cables with protective sleeves as they could make installation of
Ethernet cables more difficult.
3.8 Bundling Cables
Precautions

·
Hardware Installation and Reference Guide Installing the Access Point
Make sure the cable bundles are neat and orderly.
Bend twisted pairs naturally or in a large radius close to the connector.
Do not over tighten a cable bundle as it may reduce cable life and performance.
Bundling Steps
1. Bundle the drop UTP/STP cables and route them to the LAN1/PoE port.
2. Attach the cables in the cable tray of the rack.
3. Extend the cables under the AP and run in a straight line.
