1.3 Power Sources
The AP can be powered either with a power adapter or through Power over Ethernet (PoE).
To use a PoE device, make sure it supports the IEEE 802.3af/at PoE standard.
1.4 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.
1.5 Radiation Pattern
Because the antennas focus gains in front of the AP, signal strength in the front is stronger. Therefore, it is preferable to
install the AP towards the area where wireless coverage is most required.
When mount the AP on a wall or ceiling, install the AP towards where you stand to avoid backward coverage.
It is preferable to install the AP in a way that maximizes coverage.
When install the AP indoors, it is better to mount it on the ceiling rather than on the wall because the AP provides
greater coverage when it is installed on the ceiling.
Figure 1-3 and Figure 1-4 show the preferred wall-mount and ceiling-mount orientations of the AP operating in the 2.4
GHz and 5 GHz bands, respectively.

2 Preparing for Installation
Precautions
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.
Installation Safety
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 in a dry location 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 should be selected according to network planning and features of communication devices, 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.
2.1 Movement
Avoid moving the device frequently.
Turn off all power supplies and unplug all power cables before you remove the device.
2.2 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.
2.3 Ventilation
For proper ventilation, leave sufficient space around the AP.
2.4 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.
Table 2-1 Required Temperature and Humidity for the RG-AP530-I V2
Temperature
Relative Humidity
-10 to 50ºC
5% to 95%
2.5 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.

During installation, route cable bundles upward or downward along the sides of the rack depending on the actual situation
in the equipment room. All cable connectors should be placed at the bottom of the cabinet rather than be exposed outside
of the cabinet. Power cords should be routed upward or downward beside the cabinet close to the location of the DC
power distribution cabinet, AC power outlet, or lightning protection box.
Required Minimum Cable Bend Radius
The minimum bend radius of a power, communication or flat cable should be 5 times the overall diameter of the
cable. If the cable is constantly bent, plugged or unplugged, the bend radius should be 7 times the overall diameter.
The minimum bend radius of a coaxial cable should be 7 times the overall diameter of the cable. If the cable is
constantly bent, plugged or unplugged, the bend radius should be 10 times the overall diameter.
The minimum bend radius of a high-speed cable, such as an SFP+ cable should be 5 times the overall diameter of
the cable. If the cable is constantly bent, plugged or unplugged, the bend radius should be 10 times the overall
diameter.
Precautions for Cable Bundling
Before bundling cables, correctly mark labels and stick the labels to cables where appropriate.
Cables should be neatly and properly bundled, as shown in Figure D-1.
Figure D-1 Bundling Cables
Route and bundle power, signal, ground cables separately. When the cables are close to each other, cross them.
When power cables run parallel to signal cables, the distance between them must be greater than 30 mm.
All cable trays and their accessories shall be smooth and free from sharp edges.
Holes in metal, through which cables pass shall have smooth, well-rounded surfaces or be protected with insulating
bushings.

·
Hardware Installation and Reference Guide Appendix B: Cabling
Recommendations
Cut off excess cable tie cleanly with no sharp edges after bundling cables, as shown in Figure D-2.
Figure D-2 Cutting off Excess Cable Tie
If cables are to be bent, bind them first but do not tie cable ties within the bend to avoid stress on the cables, which
may otherwise cause the wires inside to break, as shown in Figure D-3.
Figure D-3 Do Not Tie Cable Ties within the Bend
Wrap up unnecessary or excess cables and bind them to the appropriate rack position, where device operation is not
affected and no damages occur to the device and cables during debugging.
Do not bind power cords to the rails for moving parts.
Leave a certain length of the cable connecting moving parts, such as the ground wire of the cabinet door, to avoid
stress on the cable; when moving parts are in place, ensure the excess cable length shall not contact heat sources,
sharp corners or edges. If heat sources are unavoidable, use high-temperature cables instead.
When using screws to fasten cable lugs, the bolts or nuts shall be tightened and prevented from loosening, as shown
