1 Product Overview
1.1 About the RG-SAP750-SP Access Point
The RG-SAP750-SP is a wall-mount dual-radio wireless access point (AP) designed for a wide variety of
indoor scenarios in the sectors including higher education, government, general education, finance, and
business, meeting diverse service needs. By adopting a dual-radio design, the AP delivers a combined
peak data rate of 1.167 Gbps, with up to 300 Mbps in the 2.4 GHz band and 867 Mbps in the 5 GHz band.
This eliminates the performance bottleneck. The AP is compatible with multiple devices, facilitating
connections between employees and customers.
The RG-SAP750-SP stands out with its exceptional wireless network security, RF control, mobile access,
QoS guarantee, and seamless roaming. Interworking with Ruijie's wireless access controller (AC), it
enables wireless user data forwarding, security, and access control to cope with diverse service needs.
The RG-SAP750-SP supports both local power supply and Power over Ethernet (PoE), providing you with
the flexibility to choose the power supply mode. In addition, the RG-SAP750-SP can be mounted on a wall
or ceiling, making space deployment and environmental requirements less challenging. This makes the
RG-SAP750-SP particularly suitable for scenarios, including large campuses, conference centers,
enterprise offices, and operation hotspots.
1.2 Hardware Features

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 access point to high temperature, dusts, or harmful gases. Do not install the access
point in an inflammable or explosive environment. Keep the access point away from EMI sources such
as large radar stations, radio stations, and substations. Do not subject the access point 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.
The installation site should be dry. It is not recommended that the access point be installed in a place
near the sea. 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 other items that
may be hooked by the device.
Keep tools and device away from walking areas.
2.1.2 Handling Safety
Do not move the device frequently.
Turn off all power sources and unplug all power sources and cables before moving or handling the
device.

Hardware Installation and Reference Guide Preparing for Installation
10
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 through 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.
Learn about the position of the indoor emergency power switch before installation. Cut off the power
switch in case of accidents.
Check the access point carefully before shutting down the power supply.
Do not place the device in a damp or wet location. Do not let any liquid enter the chassis.
Keep the access point far away from grounding or lightning protection devices for power equipment.
Keep the access point away from radio stations, radar stations, high-frequency high-current devices,
and microwave ovens.
2.1.4 Storage Safety
To ensure proper working of the access point, store the access point in an environment based on the
storage temperature or humidity requirements in specifications.
Caution
If the access point is powered off for more than 18 months, power on the device and run it for consecutive
24 hours to activate the device.
2.2 Installation Environment Requirements
The device must be used indoors to ensure normal operating and prolong its service life.
The installation site should 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), and ensure
that the ground of the installation site meets the requirements.

Hardware Installation and Reference Guide Preparing for Installation
11
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 and Humidity Requirements
To normal operation and a prolonged service life of the access point, maintain an appropriate
temperature and humidity in the installation environment.
The installation environment with too high or too low temperature and humidity for a long period of time
may damage the access point.
In an environment with high relative humidity, the insulating material may have bad 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 access
point.
In an environment with high temperature, the aging of insulation materials will be accelerated, greatly
reducing the reliability of the access point and severely affecting its service life.
Note
The ambient temperature and humidity of the device are measured at the point that is 1.5 m (59.06 in.)
above the floor and 0.4 m (15.75 in.) before the device when there is no protective plate in front or at the
back of the device.
2.2.5 Cleanliness Requirements
Dust poses the top threat to the running of the device. The indoor dust falling on the device may be
adhered by the static electricity, causing poor contact of the metallic joint. Such electrostatic adherence
may occur more easily when the relative humidity is low, not only affecting the service life of the device,
but also causing communication faults. The following table shows the requirements for the dust content
and granularity in the equipment room.

In addition to dust, the equipment room must strictly meet the requirements on the salt, acid and sulfide
contained in the air. These harmful substances can accelerate metal corrosion and component aging. The
equipment room should prevent the intrusion of harmful gases (such as sulfur dioxide, hydrogen sulfide,
nitrogen dioxide, and chlorine), and the specific limits are as follows:

Note
Average refers to the average value of harmful gas in one week. Maximum indicates the upper limit of
the harmful gas in one week, and maximum value can last for up to 30 minutes every day.
2.2.6 Anti-interference Requirements
Take interference prevention measures for the power supply system.
Keep the access point away from the grounding equipment or lightning and grounding equipment of
the power device as much as possible.
Keep the access point far away from high-frequency current devices such as the high-power radio
