2 Preparing for Installation
2.1 Safety Precautions
Note
●To avoid personal injury and device damage, carefully read the safety precautions before you install the
switch.
●The following safety precautions may not cover all possible dangers.
2.1.1 General Safety Precautions
Install the switch in a standard 19-inch rack.
Cut off all power supplies and unplug all power cords before mounting the switch in a rack or removing the
switch from a rack.
Do not place the switch in a wet position, and keep the switch away from liquid. Keep the chassis clean and
dust-free.
Install the switch in a position far away from heat sources.
Ensure that the rack and power distribution system are properly grounded.
Do not place the switch in walking areas.
During installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be
hooked by the chassis.
Keep tools and components away from walking areas.
2.1.2 Handling Safety
Prevent the switch from being frequently handled.
Cut off all power supplies and unplug all power cords before moving or handling the device.
Keep balance and prevent personal injuries when handling the switch.

2.1.3 Electric Safety
Warning
●Any nonstandard and inaccurate operation can cause an accident such as fire or electrical attack, thus
causing severe damages to human bodies and the switch.
●Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
Observe local regulations and specifications during electric operations. Only personnel with qualifications
can perform such operations.
Check whether there are potential risks in the work area. For example, check whether the power supply is
grounded, whether the grounding is reliable, and whether the ground is wet.
Find out the position of the indoor emergency power switch before installation. Cut off the power switch in
the case of accidents.
Make sure that the switch is powered off when you cut off the power supply.
Equip the power supply system with a leakage protector (also referred to as “leakage current switch” or
“leakage current breaker”) to automate the power cut-off in the case of power leakage or shock. When
selecting the leakage protector, observe the following rule:
○The rated leakage action current of each leakage protector is greater than twice of the theoretical
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 at most 3.5 mA, and the leakage current of the system totals 56 mA (maximum theoretical
value). A leakage protector with 30 mA rated action current supports less than nine 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 a rated action current of 30 mA supports up to four
power supplies. In this case, the 16 power supplies in the system require at least four leakage protectors
with a rated action current of 30 mAand each leakage protector supports four 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 currents of all the power supplies.
○The rated leakage non-action current of a leakage protector shall be 50% of the leakage action current.
If the non-action current value is too small, the high sensitivity level may cause the circuit to break,
causing power cut-off and service interruption even if the leakage current value is normal.
Take a leakage protector with a rated action current of 30 mA as an example. The rated leakage non-
action current shall be 15 mA. When the leakage current is less than 15mA, the protector shall not act.
Caution
●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.
●The leakage current values vary with products. For the leakage current value of each product model, see
the technical specifications in Section 1.4 Technical Specifications.

2.1.4 Static Electricity
Ensure that the grounding screw on the rear panel of the device is tightened. Ensure that the AC power
socket is a single-phase three-core power socket with protective earthing conductors (PE).
Keep the indoor installation environment clean and free of dust.
Maintain appropriate humidity conditions.
Before installing the various pluggable modules, please wear an anti-static wrist strap and make sure that it is
well grounded.
2.1.5 Laser Safety
The RG-NBS3100 switch 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 an optical transceiver is working, ensure that its port has been connected with an optical 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.
2.2 Installation Environment Requirements
Install the switch indoors to ensure its normal operation and prolonged service life. The installation site must
meet the following requirements.
2.2.1 Bearing Requirements
Evaluate the weight of the switch and its accessories (such as the rack and cables) and ensure that the ground
of the installation site observes the requirements.
2.2.2 Ventilation Requirements
Maintain a minimum clearance of 100 mm (3.94 in.) around the switch for air circulation and ventilation. After
various cables are connected, bind the cables or place them in the cable management bracket to avoid blocking
air inlets. You are advised to dust the switch at an interval of three months to avoid blocking the ventilation
openings.
2.2.3 Space Requirements
To have sufficient room for chassis handling and module swapping, you are advised to maintain an indoor
pathway of at least 800 mm (31.50 in.) wide.
Do not install the device against the wall. Instead, maintain a minimum clearance of 400 mm (15.75 in.) around
the switch for proper ventilation.

Hardware Installation and Reference Guide Preparing for Installation
12
2.2.4 Temperature and Humidity Requirements
To ensure the normal operation and prolonged service life of the switch, maintain an appropriate temperature
and humidity in the machine room. Working in an environment with too high or too low temperature and humidity
for a long period may damage the switch.
In an environment with high relative humidity, the insulating material may have poor insulation or even leak
electricity.
In an environment with low relative humidity, the insulating strip may dry and shrink, loosening screws.
In a dry environment, the internal circuits are prone to static electricity.
A high temperature can accelerate the aging process of insulation materials, greatly reducing the reliability
of the switch and severely affecting its service life.
Note
The working temperature and humidity of the switch are measured at the point that is 1.5 m (59.06 in.) above
the floor and 0.4 m (15.75 in.) before the device when there is no protective plate in front or at the back of the
switch.
2.2.5 Cleanliness Requirements
Dust poses a major threat to the switch. 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, not only affecting the service life of the switch, but also causing
communication faults. The following table describes the requirements for the dust content and granularity in the
machine room.

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

2.2.6 Grounding Requirements
Aproper grounding system is the basis for stable and reliable running. It is indispensable forpreventing lightning
strikes and interference. Carefully check the grounding conditions at the installation site according to the
grounding specifications, and complete grounding properly based on the actual situation.
Secure Grounding
Ensure that the switch is securely grounded using a yellow/green grounding cable when the switch uses the AC
power supply. Otherwise, electric shock may occur when the insulation resistance between the power supply
inside the switch and the chassis becomes small.
Caution
●The building should provide a protective ground connection to ensure that the device is connected to a
protective earth.
●The O&M personnel should check whether theAC socket is reliably connected to the protective ground of
the building. If not, the O&M personnel should use a protective earth conductor from the AC outlet
protective earth terminal to the building protective earth.
●The power socket should be installed near the device and easily accessible.
●During the device installation, the ground connection must always be made first and disconnected last.
●The cross-sectional area of the protective grounding cable should be at least 0.75 mm2(18 AWG).
●Install the switch by using 3-core power cords, with a minimum cross-sectional area of 0.75 mm2or 18
AWG per pin.
Lightning Grounding
The lightning protection system of facilities is standalone, and is composed of a lightning rod, a down conductor,
and a connector connected to the grounding system. The grounding system is usually used for power reference
grounding and safety grounding of the rack. Lightning grounding is required only for facilities and is not required
for the switch.
Note
For lightning protection, please see Section 6.3 Lightning Protection.
EMC Grounding
Grounding required for electromagnetic compatibility includes shielded grounding, filter grounding, noise and
interference suppression, and level reference. The resistance of the grounding cable should be smaller than 1
ohm.

Hardware Installation and Reference Guide Preparing for Installation
14
2.2.7 Lightning Protection Requirements
Ensure that the neutral point of theAC power socket is in good contact with the ground.
You are advised to install a power lightning arrester in front of the power input end to enhance the lightning
prevention for the power supply.
When anAC power cord is introduced from outdoors and directly connected to the power port of the switch,
the AC power port must be connected to an external lightning resistance socket to protect the switch against
lightning strokes. The lightning resistance socket is used as follows: Connect the mains AC power cord to
the lightning resistance socket and then connect the switch to the lightning resistance socket. This prevents
the current of high-voltage lightning from directly passing through the switch along the mains cable.
Note
●Lightning resistance sockets are customer-supplied.
2.2.8 EMI Requirements
All interference sources, either from outside or inside of the device or application system, affect the device by
capacitive coupling, inductive coupling, or electromagnetic waves. Electromagnetic interference (EMI) occurs
due to electromagnetic radiation or conduction, depending on 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 both a part of the interfered system and a completely electrically
isolated unit. Conduction interference occurs when interference is transferred from one unit to another unit
through cables, which are usually electromagnetic wires or signal cables connected between the source and
the sensor. 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 devices, and is difficult to shield.
Take interference prevention measures for the power supply system.
Keep the switch far away from the lightening protection and grounding system of the power device.
Keep the switch far away from high-frequency current devices such as high-power radio transmitting station
and radar launcher.
Take electromagnetic shielding measures when necessary.
2.2.9 Installation Site Requirements
Regardless of whether the device is installed in a rack or on a workbench, observe the following conditions:
Maintain a proper clearance around the air intakes and outlets for heat dissipation.
The switch is equipped with fans to draw air from side to rear. Maintain a minimum clearance of 150 mm
(5.91 in.) around the ventilation openings for heat dissipation. You are advised to install the switch in a
standard 19-inch rack. Or, place the device on a clean workbench. In hot areas, air-conditioning is
recommended.
The installation site has good cooling and ventilation.
The installation site is sturdy enough to support the weight of the switch and its accessories.
The installation site is properly grounded.
