from moisture.
Make sure the installation site is dry and flat. Take skid-proof measures.
Do not place the switch in a walking area.
Do not wear loose clothes or any other things that may be caught by the chassis during installation and
maintenance.
Moving or lifting the switch and its components requires team work. Be careful not to get hurt.
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 or 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 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.
25
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
RG-NIS3100 Series Switches Hardware Installation and Reference Guide
Preparation before Installation
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.

Product Installation
Connect the power cords of different colors to the corresponding cable
terminals. Ensure that the connector of the power cord is properly seated in
the power connector of the switch. After
plugging the power cord on the device, secure the power cord with a power cord
retention clip. Do not place anything on the top of the switch. Maintain a
minimum clearance of 100 mm (3.94 in.) around the device to ensure proper
ventilation. Do not
stack switches. 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. Keep
network cables with a length within 100 m (328.08 feet) indoors. Take
lightning protection measures if they need to be routed outdoors.
3.3.1 Mounting the Switch on a DIN Rail

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

Installing the AC Power Arrester (Surge Protection Cable Row)
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.

RG-NIS3100 Series Switches Hardware Installation and Reference Guide
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.

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

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.

When using a stiff cable, fix it near the cable lug to avoid stress on the lug and cable. Do not use self-tapping screws to fasten terminals. Bundle cables of the same type and running in the same direction into groups. Keep cables clean and straight. Cables should be tied according to the following table.
Diameter of Cable Bundle (mm) 10 10 to 30
Space Between Bundles (mm) 80 to 150 150 to 200

No knot is allowed in cabling or bundling.
The metal parts of the cold-pressed terminal blocks, such as air circuit
breakers, should not be exposed outside
of the blocks.

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.
