1 Product Overview
1.1 Overview
RG-SAP845-SP is an 802.11ax-compliant wireless access point product developed for indoor scenarios
such as higher education, government, general education, finance, and business. It uses dual-radio
technology, of which the 2.4 GHz frequency can provide up to 574 Mbps access rate and 5 GHz can provide
up to 4.804 Gbps access rate. The whole machine can provide the maximum wireless access rate of 5.378
Gbps. The ultra-fast wireless access rate takes performance out of the equation.
The important factors such as wireless network security, RF control, mobile access, service quality
assurance, and seamless roaming are fully considered in the design of RG-SAP845-SP. It works with a
wireless controller to guarantee data forwarding, security and access control of wireless users.
RG-SAP845-SP can be operated in 802.11ax, 802.11ac, and 802.11n modes concurrently. The product
supports ceiling and wall-mounted installation modes, and can be safely and conveniently installed on
ceiling and walls. RG-SAP845-SP supports local power feeding or power feeding over Ethernet (PoE). You
can flexibly select appropriate power feeding methods according to the on-site power feeding
environment. The product is especially suitable for large campus, enterprise offices, and operating
hotspots.
1.2 Appearance
RG-SAP845-SP provides two radio frequency ports, two Ethernet copper ports (LAN1 supports PoE in
compliance with IEEE 802.3af, 802.3at and 802.3bt, and LAN2/IoT port supports power feeding to IoT units
(48 V/0.27 A, MAX: 12.95 W), one 5G SFP, one RJ45 Console port, one DC power connector, one USB port,
and one reset button. The appearance is as follows:

This product uses a fanless design. When placing the AP, ensure that there is enough space around
to facilitate air circulation.
By default, the AP works in the 802.3at power feeding mode. To enable bt-related functions, run
commands.
If 802.3af is used for power feeding, when the AP starts, the 2.4 GHz and 5 GHz frequencies can only
work in 1-stream mode, and the LAN2 port and USB port cannot supply power to external devices.
If 802.3at is used for power feeding, when the AP starts, the LAN2 port and USB port cannot supply
power to external devices.

1.6 SFP Module Description
The peer device that is directly connected to the 5G SFP port of the AP supports fiber ports and copper
ports. However, the negotiated rates are different when the devices at both ends use different port rates
or use different SFP modules. For details, see Table 1-10 and Table 1-11.

Caution
1. The 2.5G SFP port of the AP does not support rate negotiation. When the O/E converter is used,
ensure that the rates of AP, O/E converter, and peer port are the same.
2. The device supports the combo ports. If both the uplink fiber port and the uplink copper port are
connected to cables, the AP will preferentially select the fiber port as the data transmission port
(automatically disables the copper port). When the cable is removed from uplink fiber port, the
copper port is automatically enabled.

2 Installation Preparation
2.1 Safety Recommendations
Note
To avoid injury to human body and equipment, read the safety recommendations in this manual
carefully before installation.
The following safety recommendations may not cover all possible hazardous situations.
2.1.1 Universal Safety Recommendations
High temperature, dust, harmful gas, flammable and explosive factors, electromagnetic interference
(large radar stations, transmitting stations, or substations) and the environment with unstable voltage,
large vibration or strong noise may affect the operating of AP. Do not install the device in such
environment.
It is strictly forbidden to install the device in places prone to water accumulation, seepage, dripping,
or condensation. When performing engineering design, comprehensively consider the factors such as
climate, hydrology, geology, earthquake, electricity, transportation, and select the address that meets
the requirements of communication device engineering environment design according to the
communication network planning and technical requirements.
The installation site should be dry, and it is not recommended to install the device in a place very close
to the sea. The distance between the device and the sea should be greater than 500 meters, and it is
not recommended to place the device on the windward side of the sea.
Do not place the device in walking areas.
During installation and maintenance, do not wear loose clothing, jewelry, or other items that may be
hooked by the chassis.
Keep tools and device away from walking areas.
2.1.2 Moving 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.
2.1.3 Electrical Safety
Warning
Irregular and improper electrical operations may cause accidents such as fire or electric shock, and
cause serious or fatal injury to human body and device.

Hardware Installation and Reference Guide Installation Preparation
12
Do not directly contact high voltage and mains or contact them through wet objects; otherwise, it may
bring fatal danger.
When performing electrical operations, comply with local regulations and rules. The relevant staff
must have the corresponding qualifications.
Check carefully whether there are potential dangers in the work area, such as whether the ground is
wet.
Before installation, you need to know the location of the emergency power switch in the room. When
an accident occurs, the power switch must be turned off.
Check carefully before turning off the power.
Do not place the device in moist places and prevent liquid from entering the device.
It is not recommended to use the AP working ground together with the ground device of electrical
equipment or lightning protection ground device, and separate them as far as possible.
Keep the device far away from wireless transmitters, radar transmitters, high-frequency high-current
devices, microwave ovens and other high-power wireless devices.
2.1.4 Storage Safety
To ensure the normal operating of the device, see the storage temperature/humidity requirements in the
specifications for the storage environment of the device.
Caution
If the storage time exceeds 18 months, the device needs to be powered on and run for 24 hours without
interruption for device activation.
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 Load-bearing Requirements
Evaluate the floor load-bearing requirements according to the actual weight of the installed device and
its accessories (such as mounting plate and power supplies), and ensure that the load-bearing capacity
of the installation site meets the requirements.
2.2.2 Ventilation Requirements
Reserve the position for vent to ensure heat dissipation. After connecting all cables, arrange them into
bundles or place them on the cable distribution frame to avoid blocking the air inlet.
