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 device 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 the device. Direct or indirect touch through a wet object on high- voltage and mains supply may bring a fatal danger.

RG-NIS3100 Series Switches Hardware Installation and Reference Guide

Preparation before Installation

If a power supply system is equipped with a leakage protector (leakage current switch or breaker), the rated leakage action current of each leakage protector is twice greater than the maximum leakage current of all the power supplies in the system. For example, if a system is equipped with 16 identical power supplies, the leakage current of each power supply is equal to or less than 3.5 mA, and the total leakage current of the system is 56 mA. A leakage protector with 30 mA rated action current supports less than ten power supplies (that is, action current of the leakage protector/2/maximum leakage current of each power supply = 30/2/3.5 4.28). In other words, the leakage protector with 30 mA rated action current supports no more than 4 power supplies. In this case, the 16 power supplies in the system require at least 4 leakage protectors with 30 mA rated action current and each leakage protector supports 4 power supplies. If power supplies in a system differ in models, the rated leakage action current of each leakage protector divided by two is greater than the sum of maximum leakage current of all the power supplies. The rated leakage non-action current of a leakage protector must be 50% of the leakage action current. The leakage protector with 30 mA rated leakage action current is used as an example. The rated leakage non-action current must be 15 mA. When the leakage current falls below 15 mA, the protector should not act. Otherwise, misoperation may easily occur due to high sensitivity and thus the leakage protector trips, devices are powered off, and services are interrupted.
To guarantee personal safety, the rated leakage action current of each leakage protector in the system must be equal to or less than 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.
For details of the leakage current value of each power supply model, see Chapter 0.
2.1.4 ESD
To prevent Electronic Static Discharge (ESD), pay attention to the following points: Proper grounding of grounding screws on the back panel of the device, and three-wire single-phase socket
with protective earth wire (PE) used as the AC power socket. Indoor dust prevention Proper humidity conditions
2.1.5 Laser
The RG-NIS3100 series switches support varying models of optical modules (Class I laser products) sold on the market. Improper use of optical modules may cause damage. Therefore, pay attention to the following points: When a fiber transceiver works, ensure that the port has been connected to 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 or look directly into the transceiver. The
transceiver emits laser light that may hurt your eyes.
Figure 2-1 Laser product marking

Do not stare into any optical port under any circumstances because this may cause permanent damage to your eyes.

RG-NIS3100 Series Switches Hardware Installation and Reference Guide

Preparation before Installation

2.2 Installation Site Requirements
To ensure the normal running and prolonged service life of the device, the installation site must meet the following requirements.
2.2.1 Load Bearing Requirements
Evaluate the load bearing requirements for the ground according to the weight of the switch and its accessories (such as the cabinet, chassis, line cards and power supply modules). Make sure the installation site meet the requirements.
2.2.2 Space Requirements
The width of the machine room corridor should be greater than 0.8 m (31.50 in.) to ensure enough space to move the chassis, and to plug and remove modules.
Do not install the switch against the wall. Maintain proper clearance around the switch for heat dissipation and switch maintenance.
2.2.3 Anti-interference Requirements
The switch is susceptible to external interference by capacitive coupling, inductive coupling, electromagnetic waves, common impedance (grounding) coupling, or conduction over conducting wires including power cords, signal cables, and output cables. Note that: In a TN grounding system, use a three- wire single-phase outlet that has a protective earth (PE) contact to allow the filter circuit in the device to eliminate interference from the power grid. Keep the switch away from high-power radio transmitters, radar transmitters, and high-frequency high-current devices. Take electromagnetic shielding measures to minimize interference when necessary, for example, use shielded interface cables. Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.
2.2.4 Ventilation
For the RG-NIS3100 series, a sufficient space (at least 10 cm distance from both sides and the back plane of the cabinet) should be reserved at the ventilation openings to ensure normal ventilation. After various cables have been connected, they should be arranged into bundles or placed on the cabling rack to avoid airflow blocking. It is recommended that you clean the switch at regular intervals (like once every three months). In particular, avoid dust from blocking the screen mesh on the back of the cabinet.
2.2.5 Temperature and Humidity
To ensure the normal operation and prolong the service life of the RG-NIS3100 series switch, 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 a high humidity, insulating materials may have bad insulation or even leaking
electricity. Sometimes the materials may suffer from mechanical performance change and metallic parts may

26

get rusted. In an environment with a low humidity, insulating strips may dry and shrink. Static electricity may occur easily
and endanger circuits on the device. In an environment with a high temperature, the router is subject to more serious harm. Its performance may
degrade significantly and various hardware faults may occur.

Notice
There is no protective plate at the front or back of the rack. The vertical height is 1.5 m above the floor. The distance from the front panel of the device is 0.4 m.

2.2.6 Cleanness

Dust poses a severe threat to the running of the device. The indoor dust falling on the device may be absorbed by the static electricity, causing bad contact of the metallic joint. Such electrostatic absorption may occur more easily when the relative humidity is low. This affects the device lifecycle and causes communication faults. Table 2-2 lists the requirements for the dust content and granularity in the equipment room.

Apart from dust, the salt, acid, and sulfide in the air in the equipment room must also meet strict requirements. This is because 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. Table 2-3 lists the requirements.

Preparation before Installation

2.2.7 Grounding
A good grounding system is the basis for stable and reliable operation of the device, preventing lightning strokes and resisting interference. Carefully check the grounding conditions at the installation site according to the grounding requirements, and perform grounding operations properly as required.
Caution Effective grounding of the switch guarantees lightning protection and interference resistance. Therefore,
connect the grounding line of the switch properly.

Safety Grounding
The device 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 the 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, 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 device installation, ensure that the ground 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 surge protection system of a facility is an independent system that consists of the lightning rod, down conductor, and connector to the grounding system, which usually shares the power reference ground and ground cable. The lightning discharge ground is targeted for the facility.
EMC Grounding
The grounding required for EMC design includes the 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 . The RG-NIS3100 series switch back plane is reserved with one grounding pole, as shown below.

2.2.8 EMI
Electro-Magnetic Interference (EMI), from either outside or inside the device 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 through 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 an 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 device, but can be controlled by a filter. Radiated interference may affect any signal path in the device and is difficult to shield. For the TN AC power supply system, the single-phase three-core power socket with protective earthing
conductors (PE) should be adopted to effectively filter out interference from the power grid through filtering circuits. Do not use the grounding device for an electrical device or anti-lightning grounding device. In addition, the grounding device of the device must be deployed far away from the grounding device of the electrical device and anti-lightning grounding device. Keep the device away from the high-power radio transmitter, radar transmitting station, and high-frequency large-current device. Take measures to shield static electricity. Lay interface cables inside the equipment room. Outdoor cabling is prohibited, avoiding damages to device signal interfaces caused by over- voltage or over-current of lightning.
2.2.9 Lightning Resistance
When the AC power cable is imported outdoors and directly connected to the power port of the RG-NIS3100 series switch, use the lightning line bank to prevent the switch from being hit by lightning shocks. In this case, connect the mains supply AC cable to the lightning line bank, and connect the switch to the lightning line bank. This helps 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 customers as required.

For wall mounting, the switch can be mounted only on a concrete or non- flammable surface.
3.4 Grounding the Switch
The switch has a grounding stud on the rear panel. Connect the grounding stud to the grounding point of the rack and then connect the grounding point of the rack to the ground bar of the equipment room.
Precautions The cross-sectional area of a grounding wire should be determined according to the maximum current. The
grounding wires should be good conductors.
Do not use bare conductors.
To avoid personal injury and device damage, connect the switch to earth ground properly. The resistance between the chassis and ground should be less than 1 ohm.
The O&M personnel should check whether the AC outlet is reliably connected to the protective ground of the building. If not, the O&M personnel should use a protective grounding wire to connect the AC outlet protective earth terminal to the building protective ground.
The power outlet should be installed near the device and easily accessible. During device installation, connect the grounding wire first and disconnect it last. The cross-sectional area of the protective grounding wire must be at least 2.5 mm2 (12 AWG).
3.5 Installing the Power Module
The power module only supports DIN rail mounting. The installation procedure is as follows: (1) Snap the top part of the DIN rail clamp on the DIN rail, pull the blade spring down, and then push the module

The external surge protection cable row must 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 surge protection cable row is fixed on the cabinet, operating table, or the wall in the equipment room using the line buttons and screws.

42

RG-NIS3100 Series Switches Hardware Installation and Reference Guide Figure C-1 Schematic Diagram for the Power Arrester

Appendix C Surge Protection

The power arrester is not provided and customers have to purchase it. Precautions for installation:
Ensure that the PE terminal of the power arrester is properly grounded. After connecting the switch AC power plug to the socket of the power arrester (surge protection cable row),
surge 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, check whether there is the poor grounding connection or
reversed connection of null and live lines. You can 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 is reversed. If the LED is still red, the arrester PE terminal is not grounded.
Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester must 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, and 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 must 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 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 check whether the LED on the board is normal.

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 applies to only the 10M/100M electrical Ethernet ports with the RJ45 connector. The Ethernet port arrester is provided by customers. For more information about arrester installation, refer to Ethernet Port Arrester Hardware Installation Guide. To prevent the performance of the Ethernet port arrester from being affected, note the following points:
Reversed direction of the arrester installation: Connect the external network cable to the IN end and connect
the switch Ethernet port to the OUT end.
Poor arrester grounding: The grounding line must 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 after grounding.
Incomplete arrester installation: If more than one port is connected to the peer device on the switch, install the
arresters on all connection ports for surge protection.

Appendix D Cabling Recommendations

Appendix D Cabling Recommendations

When RG-NIS3100 series switches are installed in standard 19-inch cabinets, cables are tied in the binding rack on the cabinet by the cabling rack, and top 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 but not outside the cabinet. Power cables are routed beside the cabinet, and top 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 surge protection box.
Requirement for the Minimum Cable Bending Radius
The bending radius of a power cord, communication cable, and flat cable should be five times greater than their respective diameters. The bending radius of these cables that often bend or is removed or installed should be seven times greater than their respective diameters.
The bending radius of a common coaxial cable should be seven times greater than its diameter. The bending radius of this type of cables that often bend or is removed or installed should be 10 times greater than its diameter.
The bending radius of a high-speed cable (for example, SFP cable) should be five times greater than its diameter. The bending radius of this type of cables that often bend or is removed or installed should be 10 times greater than its diameter.
Requirement for the Minimum Fiber Bending Radius
The diameter of a fiber tray to hold fibers cannot be 25 times less than the diameter of the fiber. When moving an optical fiber, the bending radius of the fiber should be equal to or 20 times greater than the
diameter of the fiber. During cabling of an optical fiber, the bending radius of the fiber should be equal to or 10 times greater than
the diameter of the fiber.
Precautions for Bundling Up Cables
Before bundling up cables, correctly mark labels and stick the labels to cables. Cables should be neatly and properly bundled, as shown in Figure D-1.
Figure D-1 Bundling Up Cables

45

RG-NIS3100 Series Switches Hardware Installation and Reference Guide

Appendix D Cabling Recommendations

Route and bundle power, signal, ground cables separately. When the cables are close to each other, cross
them. When power cables are parallel to signal cables, the distance between them must be 30 mm (1.18 in.).
All cable trays and their accessories must be smooth and free from sharp edges. Holes in metal, through which cables pass must have smooth or well- rounded surfaces, and be protected with
insulating bushings.
Use proper cable ties to bind cables together. Do not tie two or more cable ties to bind cables. Cut off excess cable tie cleanly with no sharp edges after bundling cables, as shown in Figure D-2.
Figure D-2 Cutting Off Excess Cable Tie

If cables are to be bent, bind them first but do not tie cable ties within the bend to avoid stress on the cables,
which may cause the wires inside to break, as shown in Figure D-3. Figure D-3 Preventing Cable Ties from Being Tied within the Bend
46

RG-NIS3100 Series Switches Hardware Installation and Reference Guide

Appendix D Cabling Recommendations

Wrap up unnecessary or excess cables and bind them to the appropriate rack position, where device operation
is not affected and no damages occur to the device and cables during commissioning.
Do not bind power cords to the rails for moving parts.
Leave a specified length of the cable connecting moving parts, such as the ground wire of the cabinet door, to
avoid stress on the cable. When moving parts are in place, ensure that the excess cable length does not contact heat sources, sharp corners, or edges. If heat sources are unavoidable, use high-temperature cables instead.
When using screws to fasten cable lugs, the bolts or nuts should be tightened and prevented from loosening, as
shown in Figure D-4.

Appendix E Site Selection

The equipment room should be at least 5 km away from the heavy pollution source such as the smelter, coal
mine, and thermal power plant, 3.7 km away from the medium pollution source such as the chemical industry, rubber industry, and electroplating industry, and 2 km away from the light pollution source such as the food manufacturer and leather plant. If the pollution source is unavoidable, the equipment room should be located on the windward side of the pollution source perennially with advanced protection.
The equipment room should be at least 3.7 km away from the sea or salt lake. Otherwise, the equipment 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 equipment room in the proximity of livestock farms. Otherwise, the equipment 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 equipment room.
The equipment 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 equipment room should be away from the residential area. Otherwise, the equipment room should meet
the construction standard in terms of noise.
Make sure that the air vent of the equipment room is away from the sewage pipe, septic tank, and sewage
treatment tank. Keep the equipment room under positive pressure to prevent corrosive gas from entering the equipment room to corrode components and circuit boards. Keep the equipment room away from industrial boiler and heating boiler.
The equipment room had better be on the second floor or above. Otherwise, the equipment room floor should
be 600 mm higher than the highest flood level ever recorded.
Make sure that 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 must meet requirements of flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the equipment 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.
