Caution
This product supports PoE power supply using photoelectric hybrid cables only when
it is connected with RG-AM5528-SF.
The AP adopts a fan-free design. Therefore, maintain sufficient clearance around the
AP for air circulation.
When a laptop using a power adapter for power supply is used to manage a single
AP over a serial port, power on the AP before connecting the serial port of the laptop
to the AP.

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 the AP 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 not recommended 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
Avoid moving the device frequently.
Cut off all the power supplies and unplug all power cords before moving or handling
the device.
