2 Preparation before Installation
2.1 Safety Suggestions
To avoid personal injury and equipment damage, please carefully read the safety suggestions before you install the
RG-S2910-H series switch.
The following safety suggestions do not cover all possible dangers.
2.1.1 Installation
Keep the chassis clean and free from any dust.
Do not place the equipment in a walking area.
Do not wear loose clothes or accessories that may be hooked or caught by the device during installation and
maintenance.
Turn off all power supplies and remove the power sockets and cables before installing or uninstalling the device.
2.1.2 Movement
Do not frequently move the device.
When moving the device, note the balance and avoid hurting legs and feet or straining the back.
Before moving the device, turn off all power supplies and dismantle all power modules.
2.1.3 Electricity
Observe local regulations and specifications when performing electric operations. Relevant operators must be
qualified.
Before installing the device, carefully check any potential danger in the surroundings, such as ungrounded power
supply, and damp/wet ground or floor.
Before installing the device, find out the location of the emergency power supply switch in the room. First cut off the
power supply in the case of an accident.
Try to avoid maintaining the switch that is powered-on alone.
Be sure to make a careful check before you shut down the power supply.
Do not place the equipment in a damp location. Do not let any liquid enter the chassis.
Any nonstandard and inaccurate electric operation may cause an accident such as fire or electrical shock, thus
causing severe even fatal damages to human bodies and equipment.
Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.
2.1.4 Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
Proper grounding of grounding screws on the back panel of the device. Use of a three-wire single-phase socket with
protective earth wire (PE) as the AC power socket.
Indoor dust prevention
Proper humidity conditions
2.1.5 Laser
The RG-S2910-H series switch supports varying models of optical modules sold on the market which are Class I laser
products. Improper use of optical modules may cause damage. Therefore, pay attention to the following when you use
them:
When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered with a
dust cap, to keep out dust and avoid burning your eyes.
When the optical module is working, do not pull out the fiber cable and stare into the transceiver interface or you may
hurt your eyes.
Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
To ensure the normal working and a prolonged durable life of the equipment, the installation site must meet the following
requirements.
2.2.1 Ventilation
For the RG-S2910-H, a sufficient space (at least 10 cm distances from both sides and the back plane of the cabinet)
should be reserved at the ventilation openings to ensure the normal ventilation. After various cables have been connected,
they should be arranged into bundles or placed on the cabling rack to avoid blocking the air inlets. It is recommended to
clean the switch at regular intervals (like once every 3 months). Especially, avoid dust from blocking the screen mesh on
the back of the cabinet.
2.2.2 Temperature and Humidity
To ensure the normal operation and prolong the service life of RG-S2910-H series switch, you should keep proper
temperature and humidity in the equipment room.
If the equipment room has temperature and humidity that do not meet the requirements for a long time, the equipment
may be damaged.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak electricity.
Sometimes the materials may suffer from mechanical performance change and metallic parts may get rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity may
occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance may
degrade significantly and various hardware faults may occur.
Therefore, the ambient temperature and humidity of the RG-S2910-H series must meet the requirements listed in Table
2-1:
Table 2-1 Temperature and Humidity Requirements of the RG-S2910-H Series Switch
Temperature
Relative Humidity
0 ºC to 50ºC
10% to 90%
The requirements for the sampling site of the temperature and humidity in the operating environment of the device
are as follows:
There is no protective plate at the front or back of the equipment rack.
The vertical height is 1.5 m above the floor.
The distance from the front panel of the equipment is 0.4 m.
2.2.3 Cleanness
Dust poses a severe threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the useful life of the equipment, but also causing communication faults.
Table 2-2 shows the requirements for the dust content and granularity in the equipment room.

Dust
Unit
Density
Diameter≥0.5μm
Particles/m3
≤3.5×106
Diameter≥5μm
Particles/m3

Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements, as such
poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room
should be protected from the intrusion of harmful gases such as sulfur dioxide, sulfured hydrogen, nitrogen dioxide, and
chlorine), whose requirements are listed in Table 2-3.

Both average and maximum value are measured for a week. The switch cannot be placed in the environment with
the maximum density for over 30 minutes every day. ..
2.2.4 Grounding
A good grounding system is the basis for the stable and reliable operation of the RG-S2910-H series switch. It is the chief
condition to prevent lightning stroke and resist interference. Please carefully check the grounding conditions on the
installation site according to the grounding requirements, and perform grounding operations properly as required.
Effective grounding of the switch is an important guarantee for lightning protection and interference resistance.
Therefore, connect the grounding line of the switch properly.
Safety Grounding
The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when the insulating resistance decreases the power supply and the enclosure in the equipment, electric shock may occur.
The building must provide protective grounding connection to ensure that the device is connected to the protection
location.
The installation and maintenance personnel must check whether the A.C. socket is well connected to the protection
location of the building, if not, they should use a protective grounding wire to connect the grounding end of the A.C.
socket to the building's protection location.
The power supply socket must be installed in a place that is near to the device and where users can operate the
device easily.
Before the installation of the device, make sure that ground connection is connected at first and disconnected finally.
The sectional area of the protective grounding wire should be at least 0.75 mm2 (18 AWG).
Use the 3-core power supply line. The sectional area of each pin should be at least 0.75 mm2 or 18 AWG.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, download
conductor and the connector to the grounding system, which usually shares the power reference ground and yellow/green
safety cable ground. The lightning discharge ground is for the facility only, irrelevant to the equipment.
EMC Grounding
The grounding required for EMC design includes shielding ground, filter ground, noise and interference suppression, and
level reference. All the above constitute the comprehensive grounding requirements. The resistance of earth wires should
be less than 1 ohm. The RG-S2910-H series switch back plane is reserved with one grounding pole, as shown in Figure
2-1.
Figure 2-1Grounding of RG-S2910-H
2.2.5 Lightning Resistance
When the AC power cable is imported outdoors and directly connected to the power port of the RG-S2910-H series switch,
lightning line bank should be adopted to prevent the switch from being hit by lightning shocks. Usage of the lightning line
bank: Connect the mains supply AC cable to the lightning line bank. Then, connect the switch to the lightning line bank.
This can help to prevent the current of high-voltage lightning from passing the switch directly through the mains supply
cable to a certain extent.
The lightning line banks are not provided and should be purchased by users as required.
For the usage of lightning line banks, refer to their related manuals.
2.2.6 EMI
Electro-Magnetic Interference (EMI), from either outside or inside the equipment or application system, affects the system
in the conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation.
There are two types of electromagnetic interference: radiated interference and conducted interference, depending on the
type of the transmission path.
When the energy, often RF energy, from a component arrives at a sensitive component via the space, the energy is
known as radiated interference. The interference source can be either a part of the interfered system or a completely
electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection between
the source and the sensitive component, along which cable the interference conducts from one unit to another. Conducted
interference often affects the power supply of the equipment, but can be controlled by a filter. Radiated interference may
affect any signal path in the equipment and is difficult to shield.
For the AC power supply system TN, single-phase three-core power socket with protective earthing conductors (PE)
should be adopted to effectively filter out interference from the power grid through the filtering circuit.
The grounding device of the switch must not be used as the grounding device of the electrical equipment or
anti-lightning grounding device. In addition, the grounding device of the switch must be deployed far away from the
grounding device of the electrical equipment and anti-lightning grounding device.
Keep the equipment away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
Measures must be taken to shield static electricity.
Interface cables should be laid inside the equipment room. Outdoor cabling is prohibited, avoiding damages to
device signal interfaces caused by over-voltage or over-current of lightning.

Appendix C Lightning Protection
Installing AC Power Arrester (lightning protection cable row)
The external lightning protection cable row shall be used on the AC power port to prevent the switch from being struck by
lightning when the AC power cable is introduced from the outdoor and directly connected to the power port of the switch.
The lightning protection cable row is fixed on the cabinet, operating table or the wall in the machine room using the line
buttons and screws.
Figure C-1 Schematic Diagram for the Power Arrester
The power arrester is not provided and the user shall purchase it to address the practical requirement.
Precautions for installation:
Make sure that the PE terminal of the power arrester has been well-grounded;
After connecting the switch AC power plug to the socket of the power arrester (lightning protection cable row),
lightning protection function implements if the RUN LED is Green and the ALARM LED is OFF.
If the ALARM LED on the power arrester is Red, you shall check what the reason is, poor grounding connection or
the reversed connection of the Null and Live lines: Use the multimeter to check the polarity of the power socket for
the arrester when the LED is Red, if the N line is on the left and the L line is on the right, the arrester PE terminal is
not grounded; if the L line is on the left and the N line is on the right, the polarity of the arrester power cable shall be
reversed; if the LED is still Red, it is confirmed that the arrester PE terminal has not been grounded.
Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester shall be connected to the switch to prevent the switch damage by
lightning before the outdoor network cable connects to the switch.
Tools: Cross or straight screwdriver, Multimeter, Diagonal pliers
Installation Steps:
1. Tear one side of the protection paper for the double-sided adhesive tape and paste the tape to the framework of the
Ethernet port arrester. Tear the other side of the protection paper for the double-sided adhesive tape and paste the
Ethernet port arrester to the switch framework. The paste location for the Ethernet port arrester shall be as close to
the grounding terminal of the switch.
2. Based on the distance of the switch grounding terminal, cut the grounding line for the Ethernet port arrester and firmly
tighten the grounding line to the grounding terminal of the switch.
3. Use the multimeter to check whether the grounding line for the arrester is in good contact with the switch grounding
terminal and the framework.
4. According to the description on the Ethernet Port Arrester Hardware Installation Guide, connect the arrester using the
adapter cable(note that the external network cable is connected to the end of IN, while the adapter cable connected to the
switch is connected to the end of OUT) and observe whether the LED on the board is normal or not.
5. Use the nylon button to bundle the power cables.
Figure C-2 Schematic Diagram for the Ethernet port Arrester Installation
The Ethernet port arrester is only for the 10M/100M copper Ethernet ports with the RJ-45 connector;
The Ethernet port arrester is not provided, the user can purchase them to address their own practical requirements.
For the detailed information during the arrester installation, please refer to Ethernet Port Arrester Hardware
Installation Guide, which contains the technical specification and the maintenance and installation of the arrester.
You may pay attention to the following conditions during the actual installation to avoid influencing the performance of the
Ethernet port arrester:
Reversed direction of the arrester installation. You shall connect the external network cable to the “IN” end and
connect the switch Ethernet port to the “OUT” end.
Poor arrester grounding. The length of the grounding line should be as short as possible to ensure that it is in good
contact with the switch grounding terminal. Use the multimeter to confirm the contact condition after the grounding.
Incomplete arrester installation. If there is more than one port connected to the peer device on the switch, it needs to
install the arresters on all connection ports for the purpose of the lightning protection.
Appendix D Cabling Recommendations in Installation
When RG-S2910-H series switches are installed in standard 19-inch cabinets, the cables are tied in the binding rack on
the cabinet by the cabling rack, and top cabling or bottom cabling is adopted according to the actual situation in the
equipment room. All cable connectors should be placed at the bottom of the cabinet in an orderly manner instead of
outside the cabinet easy to touch. Power cables are routed beside the cabinet, and top cabling or bottom cabling is
adopted according to the actual situation in the equipment room, such as the position of the DC power distribution box, AC
socket, or lightning protection box.
Requirement for the minimum cable bend radius
The bend radius of a power cord, communication cable, and flat cable should be greater than five times their
respective diameters. The bend radius of these cables that often bend or suffer removal/insertion should be greater
than seven times their respective diameters.
The bend radius of a common coaxial cable should be greater than seven times its diameter. The bend radius of this
type of cables that often bend or suffer removal/insertion should be greater than 10 times its diameter.
The bend radius of a high-speed cable (SFP cable, for example) should be greater than five times its diameter. The
bend radius of this type of cables that often bend or suffer removal/insertion should be greater than 10 times its
diameter.
Requirement for the minimum fiber bend radius
The diameter of a fiber tray to hold fibers cannot be less than 25 times the diameter of the fiber.
When moving an optical fiber, the bend radius of the fiber should be equal to or greater than 20 times the diameter of
the fiber.
During cabling of an optical fiber, the bend radius of the fiber should be equal to or greater than 10 times the
diameter of the fiber.
Precautions for Bundling up Cables
Before bundling cables, correctly mark labels and stick the labels to cables where appropriate.
Cables should be neatly and properly bundled, as shown in Figure D-1.
Figure D-1 Bundling Up Cables (1)
Cables of different types (such as power cords, signal cables, and grounding cables) should be separated in cabling
and bundling. When they are close, crossover cabling can be adopted. In the case of parallel cabling, power cords
and signal cables should maintain a space equal to or greater than 30 mm.
The binding rack and cabling slot inside and outside the cabinet should be smooth, without sharp corners.
The metal hole traversed by cables should have a smooth and fully rounding surface or an insulated lining.
Proper buckles should be selected to bundle up cables. It is forbidden to connect two or more buckles to bundle up
cables.
After bundling up cables with buckles, you should cut off the remaining part. The cut should be smooth and trim,
without sharp corners, as shown in Figure D-2.
Figure D-2 Bundling Up Cables (2)
When cables need to bend, you should first bundle them up. However, the buckle cannot be bundled within the bend
area. Otherwise, significant stress may be generated in cables, breaking cable cores. As shown in Figure D-3.
Figure D-3 Bundling Up Cables (3)
Cables not to be assembled or remaining parts of cables should be folded and placed in a proper position of the
cabinet or cabling slot. The proper position indicates a position that will not affect device running or cause device
damage or cable damage during commissioning.
The power cords cannot be bundled on the guide rails of moving parts.
The power cables connecting moving parts such as door grounding wires should be reserved with some access after
assembled. When the moving part reaches the installation position, the remaining part should not touch heat sources,
sharp corners, or sharp edges. If heat sources cannot be avoided, high-temperature cables should be used.
When using screw threads to fasten cable terminals, the bolt or screw must be tightly fastened, and anti-loosening
measures should be taken, as shown in Figure D-4.
Figure D-4 Cable Fastening
The hard power cable should be fastened by the terminal connection area to prevent stress.
Do not use self-tapping screws to fasten terminals.
Power cables of the same type and in the same cabling direction should be bundled up into cable bunches, with
cables in cable bunches clean and straight.
Binding by using buckles should be performed according to Table D-1.
Cable Bunch Diameter (mm)
Binding Space (mm)
10
80-150
10-30
150-200
30
200-300
No knot is allowed in cabling or bundling.
For solder-less terminal blocks (such as air switches) of the cold pressing terminal type, the metal part of the cold
pressing terminal should not be exposed outside the terminal block when assembled
Appendix E Site Selection
The machine room should be at least 5km away from the heavy pollution source such as the smelter, coal mine and
thermal power plant, 3.7km away from the medium pollution source such as the chemical industry, rubber industry
and electroplating industry, and 2km away from the light pollution source such as the food manufacturer and leather
plant. If the pollution source is unavoidable, the machine room should be located on the windward side of the
pollution source perennially with advanced protection.
The machine room should be at least 3.7km away from the sea or salt lake. Otherwise, the machine room must be
sealed, with air conditioner installed for temperature control. Saline soil cannot be used for construction. Otherwise,
you should select devices with advanced protection against severe environment.
Do not build the machine room in the proximity of livestock farms. Otherwise, the machine room should be located
on the windward side of the pollution source perennially. The previous livestock house or fertilizer warehouse cannot
be used as the machine room.
The machine room should be firm enough to withstand severe weather conditions such as windstorm and heavy rain
as well as away from dust. If the dust is unavoidable, keep the door and window away from the pollution source.
The machine room should be away from the residential area. Otherwise, the machine room should meet the
construction standard in terms of noise.
Make sure the air vent of the machine room is away from the sewage pipe, septic tank, and sewage treatment tank.
Keep the machine room under positive pressure to prevent corrosive gas from entering the machine room to corrode
components and circuit boards. Keep the machine room away from industrial boiler and heating boiler.
The machine room had better be on the second floor or above. Otherwise, the machine room floor should be 600mm
higher than the highest flood level ever recorded.
Make sure there are no cracks or holes in the wall and floor. If there are cable entries in the wall or window, take
proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which should be up to the
standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the machine room sealed.
The steel door is recommended for soundproofing.
Sulfur-containing materials are forbidden.
Pay attention to the location of the air conditioner. Keep the air conditioner from blowing wind straight toward the
device or blowing water drops from the window or air vent toward the device.
