2.1 Safety Precautions
To avoid body injury and device damage, please carefully read the safety precautions before you install the RG-
CS86-20XS4VS2QXS-D switch.
The following safety precautions do not cover all possible dangers.
2.1.1 Installation
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
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 Electricicity
Connect the device to a grounded output socket by a power cord.
For pluggable devices, the socket should be easily accessible.
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.
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.

Ruijie RG-CS86-20XS4VS2QXS-D Switches Hardware Installation and Reference Guide
- 10 -
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
The RG-CS86-20XS4VS2QXS-D switch has more than one input power supply. Please unplug all power cables after
powering off the switch.
If a power supply system isequipped 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 actioncurrent 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 systemdiffer in models,
the rated leakage action current of each leakage protector divided by two is greaterthan 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 Prevention
The RG-CS86-20XS4VS2QXS-D 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 RG-CS86-20XS4VS2QXS-D 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.
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

Ruijie RG-CS86-20XS4VS2QXS-D Switches Hardware Installation and Reference Guide
- 11 -
Among the modules supported by the RG-CS86-20XS4VS2QXS-D switch, there are a great number of optical modules
that are Class I laser 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.
2.1.6 Storage
To ensure the normal operation of the device, maintain a proper storage environment in accordance with storage
temperature or humidity requirements according to the Specifications table.
If the device storage time exceeds 18 months, you must power on the device and keep it running for 24 hours
continuously.
2.2 Installation Site Requirements
Install the RG-CS86-20XS4VS2QXS-D 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
Make sure the cabinet comply with the following conditions if the RG-CS86-20XS4VS2QXS-D 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 RG-CS86-20XS4VS2QXS-D switch and its installation
accessories.
Be sure that the dimensions of the cabinet is appropriate for installation of the RG-CS86-20XS4VS2QXS-D 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
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
To ensure the normal operation and a prolonged service life of the RG-CS86-20XS4VS2QXS-D 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.

Ruijie RG-CS86-20XS4VS2QXS-D Switches Hardware Installation and Reference Guide
- 12 -
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.
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 RG-CS86-20XS4VS2QXS-D switch:
Model
Working Temperature
Working Humidity
RG-CS86-20XS4VS2QXS-D
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 Cleanliness
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 ≥0.5 µm)
≤3.5 x 106
Dust particles (diameter ≥5 µm)
≤3 x 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

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
A good grounding system is the basis for the stable and reliable operation of the RG-CS86-20XS4VS2QXS-D 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

Ruijie RG-CS86-20XS4VS2QXS-D Switches Hardware Installation and Reference Guide
- 13 -
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 0.1Ω. 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
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 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.
