2 Preparing for Installation
2.1 Safety Precautions
Warning
To avoid personal injury and device damage, carefully read the safety precautions before you install the
RG-IF2920U-12GT1XS-DC.
The following safety precautions may not cover all possible dangers.
2.1.1 Mounting
Keep the chassis clean and dust-free.
Do not place the device in a walking area.
During installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be
hooked by the chassis.
Cut off all the power supplies and unplug all power cords before handling the switch.
2.1.2 Handling
Avoid handling the device frequently.
Keep balance and prevent personal injuries when handling the device.
Cut off all the power supplies and unplug all power cords before moving or handling the switch. Avoid scalds
because the housing surface is hot.
2.1.3 Electricity
Observe local regulations and specifications during electric operations. Only qualified personnel can perform
such operations.
Before installing the device, check whether there are hidden risks in the operating environment of the device.
For example, check whether the power socket is grounded and whether the ground is wet.
Determine the location of the indoor emergency power supply switch before installing the device. When an
accident occurs, immediately cut off all power supplies.
Do not maintain the device by yourself when the device is powered on.
Make sure that the device is powered off when you cut off the power supply.
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 through wet objects with high voltage or mains power supply may be fatal.
To guarantee personal safety, the rated leakage action current of each leakage protector in the system
must be less than or equal to 30 mA (human body safety current is 30 mA). When twice of the total
leakage current of the system is greater than 30 mA, the system must be equipped with two or more
leakage protectors.

When this device is running, the surface temperature of the top cover is high. Install and use it in the area
that can only be accessed by maintenance personnel or skilled technicians.
2.1.4 ESD
To prevent damage caused by static electricity, pay attention to the following points:
Keep the indoor installation environment clean and dust-free.
Keep the indoor humidity within a certain range.
2.1.5 Laser
The RG-IF2920U-12GT1XS-DC supports various types of optical transceivers available in the market, and
these optical transceiver are Class I laser products. Improper use of an optical transceiver may cause damage.
Therefore, pay attention to the following:
When a fiber transceiver works, ensure that the port has been connected with a fiber or covered by a dust cap
to keep out dust and prevent it from burning your eyes.
When an optical transceiver is working, do not look into its port after removing the optical fiber. Otherwise, your
eyes may be hurt.
Warning
Do not approach or look into any optical port under any circumstances. This may cause permanent damage to
your eyes.
2.1.6 Storage
To ensure proper working of the device, store the device in an environment based on the storage temperature or
humidity requirements in specifications.
Caution
If the device has been 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 Site Requirements
The installation site must meet the following requirements to ensure the normal operation and prolonged
service life of the device.
2.2.1 Ventilation
For the RG-IF2920U-12GT1XS-DC, maintain sufficient clearance on both sides of the chassis and above the
chassis for air circulation. After various cables are connected, bind the cables or place them in the cable
management bracket to avoid blocking air inlets. Dust the device every three months to avoid blocking the
ventilation openings on the housing.
The RG-IF2920U-12GT1XS-DC uses natural heat dissipation, and the heat is primarily dissipated through the
housing. The surface temperature of the device is high. It is crucial to install the device in a restricted-access

Hardware Installation and Reference Guide Preparing for Installation

area that offers sufficient ventilation, only accessible to authorized personnel such as maintenance staff,
professionals, or relevant technical personnel.
2.2.2 Temperature and Humidity
To ensure the normal operation and service life of the switch, maintain an appropriate temperature and humidity
in the environment where the switch is used.
Prolonged exposure of the switch to a high relative humidity environment can result in compromised insulation
of the insulating material, potentially leading to electrical leakage. Additionally, the mechanical properties of
materials may undergo alterations, and there is an increased risk of corrosion for metal components.
Extended storage of the switch in a low relative humidity environment can result in the shrinkage of insulating
strips, leading to the loosening of fastening screws. Additionally, the occurrence of static electricity becomes
more likely, which poses a risk of damaging internal circuits of the switch.
Extended exposure of the switch to a high ambient temperature environment can result in amplified damage.
The elevated temperature accelerates the aging process of insulating materials, significantly diminishing the
performance and reliability of the switch while severely impacting its service life.

0°C to 45°C (32°F to 113°F)
10% to 90%
2.2.3 Cleanliness
Dust poses a major threat to the device. The indoor dust takes on a positive or negative static electric charge
when falling on the switch, causing poor contact of the metallic joint. Such electrostatic adhesion may occur
more easily when the relative humidity is low, affecting the service life of the switch and causing communication
faults.

Apart from dust, the salt, acid, and sulfide in the air of the equipment room must meet strict requirements.
These harmful substances will accelerate metal corrosion and component aging. Therefore, the equipment
room should be properly protected against the intrusion of harmful gases, such as sulfur dioxide, hydrogen
sulfide, nitrogen dioxide, and chlorine gas.

2.2.4 Anti-interference
The switch is susceptible to external interference by capacitive coupling, inductive coupling, electromagnetic
waves, common impedance (ground) coupling, or conduction over power lines, signal lines, and output lines.
Pay attention to the following points:
The switch should be located far away from the high-power radio launch pads, radar launch pads, and
high-frequency large-current devices.
Use electromagnetic interference (EMI) shielding such as shielded interface cables to minimize interference
when necessary.
Route interface cables only indoors to prevent signal ports from being damaged by overvoltage or overcurrent
caused by lightning strikes.
