Caution
1. The 2.5G SFP port of theAP 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.
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.

Hardware Installation and Reference Guide Installation Preparation
12
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.
2.2.3 Space Requirements
To facilitate heat dissipation and maintenance of the device, do not install the device against the wall. Leave a
certain space (not less than 0.4 m) for the left and right panels to facilitate heat dissipation.
2.2.4 Temperature and Humidity Requirements
To ensure the normal operating of the device and prolong its service life, maintain certain temperature and
humidity in the equipment room.
If the equipment room is in the environment that does not meet the temperature/humidity requirements for a long
time, the device may be damaged.
When the relative humidity is too high, it is easy to cause poor insulation of insulating materials and even
mechanical properties such as leakage.
When the relative humidity is too low, the insulating washer may dry out and cause loosening of the fastening
screws.
In dry environment, it is easy to generate static electricity and harm the internal circuit of the device.

Hardware Installation and Reference Guide Installation Preparation
13
In the high-temperature environment, the aging process of insulating materials will be accelerated, the
reliability of the device will be greatly reduced, and its service life will be seriously affected.
Note
The temperature and humidity of the working environment of the device are measured at 1.5 m above the floor
and 0.4 m in front of the device rack when there is no protective plate before and after the rack.
2.2.5 Cleanliness Requirements
Dust is a major hazard to device operating. Indoor dust falling on the device body will cause electrostatic
adsorption and poor contact of metal contacts. Especially when the indoor relative humidity is low, it is more
likely to cause electrostatic adsorption, which will not only affect the service life of the device, but also cause
communication failures. The dust content and granule size requirements in the equipment room are as follows:
