2 Preparation before Installation
2.1 Safety Precautions
To avoid body injury and device damage, please carefully read the safety precautions before you install the
NX-6510S-20X4S2Q series switch.
The following safety precautions do not cover all possible dangers.
2.1.1 Installation Safety
Keep the chassis clean and dust-free.
Do not place the device in walking areas.
Do not wear loose clothes, ornaments or any other things that may be hooked by the chassis during the
installation and maintenance.
Turn off all power supplies and unplug all power cords and cables before the installation or the dismantling.
2.1.2 Removal Safety
Avoid frequent removals after the device is installed.
Turn off all power supplies and unplug all power cords and cables before the installation or the dismantling.
When removing the device, pay attention to the balance and avoid hurting legs and feet or straining the back.
When the device is being removed, do not hold the power supply handle or the fan handle for these parts are not
designed for bearing the entire weight of the device. It will cause damage to the device or to your body if you hold
these parts when removing the device.
To reduce the weight of the chassis during the removal, dismantle the expansion module, fan module and the
power supply module first.
Install and operate the device in places where removing is restricted.
2.1.3 Electric Safety
Observe local regulations and specifications when electric operations are performed. Relevant operators must be
qualified.
Carefully check any potential danger in the working area, such as ungrounded power supply, unreliable grounding
of the power supply, and damp/wet ground.
Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in the case of an accident.
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.

Nodexon NX-6510S-20X4S2Q Series Switch Product Guide
Any nonstandard and inaccurate electrical operation can cause accidents such as fires or electrical attacks, thus
causing severe, or even fatal damages to human bodies and the devices.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
The NX-6510S-20X4S2Q series switch has more than one input power supply. Please unplug all power
cables after powering off the switch.
If a power supply system is equipped with a leakage protector (also referred to as "leakage current switch" or
"leakage current breaker"), 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 equal to or less than 1.75 mA, and
the leakage current of the system totals 28 mA. 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 = 30/2/1.75 = 8.57). In other words, the leakage protector with 30 mA rated action current supports
no more than eight power supplies. In this case, the 16 power supplies in the system require at least two leakage
protectors with 30 mA rated action current and each leakage protector supports eight 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. Take a leakage protector with 30 mA rated
leakage action current as an example. The rated leakage non-action current shall be 15 mA. When the leakage
current is below 15 mA, the protector shall 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 the leakage current value of each power supply model, see the power supply model parameter table in
Chapter 1.
2.1.4 Electrostatic Discharge Damage Precautions
The NX-6510S-20X4S2Q series switch adopts multiple measures to prevent electrostatic discharge damage. But if the
electrostatic exceeds certain limit, it can still cause great damages to the circuitry and the device. In networks
connected by the NX-6510S-20X4S2Q series switch, the major sources of electrostatic induction include outdoor high
voltage transmission cables, lightening, indoor floor materials and the machine structure.
The device and the floor are well grounded.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
When the pluggable modules of the switch are being installed, wear anti-static wrist strap and make sure the
anti-static wrist strap is well grounded.
Do not use bare hand to directly touch the components and the printed-circuit board (PCB) when the boards are
used.
Use an anti-static shielding bag to properly store the board.

Nodexon NX-6510S-20X4S2Q Series Switch Product Guide
Do not let any clothes touch a circuit board. An anti-static wrist strap can only prevent human static electricity from
damaging the circuit board, but cannot prevent any static electricity on clothes.
2.1.5 Laser Safety
Among the modules supported by the NX-6510S-20X4S2Q series switch, there are a great number of optical modules
that are ClassⅠlaser product.
Precautions:
When a fiber transceiver works, ensure that the port has been connected with a fiber or has been covered by a
dust cap so as to keep out dust and prevent it from burning your eyes.
Do not stare at any fiber port.
Do not stare at any fiber port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
Install the NX-6510S-20X4S2Q series switch indoors. To ensure normal operation and a prolonged service life of the
device, the installation site must meet the following requirements.
2.2.1 Rack Mounting Requirements
Make sure the cabinet comply with these conditions if the NX-6510S-20X4S2Q series switch is installed in the cabinet:
Install the switch in an open cabinet as much as possible. If you install the switch inside a closed cabinet, be sure
that the cabinet has a good ventilation and heat dissipation system.
Be sure that the cabinet is firm enough to bear the weight of the NX-6510S-20X4S2Q series switch and its
installation accessories.
Be sure that the dimensions of the cabinet is appropriate for installation of the NX-6510S-20X4S2Q series
switch that can reserve a certain space for the front, back, left and right panels for heat dissipation.
The cabinet should be properly grounded.
2.2.2 Ventilation Requirements
Maintain a minimum clearance of 200mm around the switch for ventilation. After various cables are connected, bundle
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.
2.2.3 Temperature and Humidity Requirements
To ensure the normal operation and a prolonged service life of the NX-6510S-20X4S2Q series switch, maintain an
appropriate temperature and humidity in the equipment room. The equipment room with too high or too low
temperature and humidity for a long period of time may damage the equipment.
In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity. And sometimes the materials may suffer from mechanical performance change and metallic parts may
get rusted.

Nodexon NX-6510S-20X4S2Q Series Switch Product Guide
On the other hand, in an environment with low relative humidity, the insulating strip may dry and shrink, and static
electricity may occur easily and endanger the circuit on the device.
In an environment with high temperature, the equipment is subjected to even greater harm, as its performance
may degrade significantly and its service life may be shortened at high temperature for long that expedites the
aging process.
Temperature and humidity requirements of the NX-6510S-20X4S2Q series switch:
Model Working Temperature Working Humidity
RG-S6120-20XS4VS2QXS 0°C to 50°C (32°F to 113°F) 10% to 90% non-condensing
The temperature and humidity are measured at the point that is 1.5 m above the floor and 0.4 m before the device
when there is no protective plate in front or at the back of the device rack.
2.2.4 Cleanness Requirements
Dust poses the top threat to the running of the device. The indoor dust falling on the device may be adhered by the
static electricity, causing poor contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the service life of the device, but also causing communication faults. The
following table shows the requirements for the dust content and granularity in the equipment room.
Substance
Concentration Limit (particles/m3)
Dust particles (diameter ≥0.5μm)
≤3.5×106
Dust particles (diameter ≥5μm)
≤3×104
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 (for example, SO2, H2S, NO2and Cl2), whose requirements are
listed in the following table.
Gas
Average (mg/m3)
Maximum (mg/m3)
SO2
0.3
1.0
H2S
0.1
0.5
NO2

The Average refers to the average limit of harmful gas in one week. The Maximum value is the upper limit of the
harmful gas in one week, and maximum value can last for up to 30 minutes every day.
2.2.5 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the NX-6510S-20X4S2Q series switch. It
is the key 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 properly as needed.
Safety Grounding

Nodexon NX-6510S-20X4S2Q Series Switch Product Guide
The device using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise,
when the insulating resistance decreases between the power supply and the enclosure in the device, electric shock
may occur.
The building installation shall provide a means for connection to protective earth, and the device is to be
connected to that means.
Lightning Grounding
The lightning protection system of the facility is an independent system that consists of the lightning rod, down lead
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, not for the device.
For lightning protection, refer to Appendix C.
EMC Grounding
The ground 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 grounding resistance should
be less than 1Ω. There is one grounding pole at the right bottom of the chassis. The grounding poles are pasted with
conspicuous warning labels.
Figure 2-1 EMC grounding
2.2.6 EMI Consideration
Various interference sources, from either outside or inside the device or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation. There are two types of
electromagnetic interferences: radiated interference and conducted interference, depending on the type of the
propagation 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 sensor. Interference along the cable the interference is transmitted from one

Nodexon NX-6510S-20X4S2Q Series Switch Product Guide
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.
Effective measures should be taken for the power system to prevent electric grid interference.
The working ground of the routers should be properly separated and kept as far as possible from the grounding
device of the power device or the anti-lightning grounding device.
Keep the device away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
Measures must be taken to isolate static electricity.
2.3 Precaution for Fiber Connection
Before connecting the fibers, you should ensure that the type of optical connector and the type of fibers match the type
of the optical interface used. Moreover, you should pay attention to the Tx and Rx directions of the fiber. The Tx end of
this device should be connected to the Rx end of the peer device, and the Rx end of this device to the Tx end of the
peer device.
