2.1.4 ESD
To prevent Electronic Static Discharge (ESD), pay attention to the following:
Connect the device's circuit to the ground.
Clear up the dust.
Maintain the proper humidity.
2.1.5 Laser
Among the modules supported by the QSW-6200 series, many are Class I laser products. Therefore, pay attention to the
following when using them:
When a fiber transceiver works, ensure that the port has been connected with an optical fiber or is covered with a
dust cap, to keep out dust and avoid burning your eyes.
Do not stare into the optical ports.
Do not approach or stare into any optical port, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
The QSW-6200 series must be used indoors. To ensure its functioning and prolong its service life, the installation site
must meet the following requirements.
The machine room should be at least 5km away from the heavy pollution source such as the smelter, coal mine
and thermal power plant, 3.7km away from the medium pollution source such as the chemical industry, rubber
industry and electroplating industry, and 2km away from the light pollution source such as the food manufacturer
and leather plant. If the pollution source is unavoidable, the machine room should be located on the windward
side of the pollution source perennially with advanced protection.
The machine room should be at least 3.7km away from the sea or salt lake. Otherwise, the machine 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 machine room in the proximity of livestock farms. Otherwise, the machine 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 machine room.
The machine 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 machine room should be away from the residential area. Otherwise, the machine room should meet the
construction standard in terms of noise.
Make sure the air vent of the machine room is away from the sewage pipe, septic tank, and sewage treatment
tank. Keep the machine room under positive pressure to prevent corrosive gas from entering the machine room
to corrode components and circuit boards. Keep the machine room away from industrial boiler and heating boiler.
QSW-6200 Series Switch Hardware Installation and Reference Guide 26
www.qtech.ru
The machine room had better be on the second floor or above. Otherwise, the machine room floor should be
600mm higher than the highest flood level ever recorded.
Make sure 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 should be up to the
standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
Keep the door and the window closed to make the machine 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.
2.2.1 Ventilation
QSW-6200 should be placed at least 10 cm away from surrounding walls to effective ventilation and heat dissipation.
Cables should be bunched or put on the cable frame after being connected in order to prevent blocking the air intake.
2.2.2 Temperature and Humidity
The temperature and humidity in the room must be stable to ensure the device's proper functioning and prolong its service
life.
Continuous improper temperature and humidity will cause damage to the device.
High relative humidity will reduce the insulation of insulation materials and cause electric leakage. Sometimes it may lead
to changes in the mechanical characters of materials and rust metal components.
Low relative humidity will dry the insulation sheets and generate static electricity, which will damage the electric circuits of
the device.
High temperature will large affect the device's reliability, shorten its service life and accelerate its aging.
Temperature and humidity requirements of the QSW-6200 series are as follows:
Temperature
Relative Humidity
0 ºC to 50ºC
10% to 90%
The working temperature and humidity are measured 1.5 m above the ground and 0.4 m away from the front plat and
when the chassis’ front and rear protective plates are removed.
2.2.3 Cleanness
Dust poses the top threat to the running of the equipment. The indoor dust falling on the equipment may be adhered by
the static electricity, causing bad contact of the metallic joint. Such electrostatic adherence may occur more easily when
the relative humidity is low, not only affecting the use life of the equipment, but also causing communication faults. The
following table shows 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; 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, NO2 and Cl2), whose requirements are
listed in the following table.

2.2.4 Grounding
A good grounding system is the basis for the stable and reliable operation of the QSW-6200 series, preventing lightning
stroke and resisting interference. Please carefully check the grounding conditions on the installation site according to the
grounding requirements, and perform grounding operations properly as required.
The correct connection of grounding lines guarantees the lighting and interference resistance of switches and must
be performed with precision.
Safety Grounding
The equipment 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.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, downlead
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, but unnecessary for equipment.
EMC Grounding
The grounding required for EMC design includes shielding grounding, filter grounding, noise and interference suppression,
and level reference. All the above constitute the comprehensive grounding requirements. The grounding resistance
should be less than 1Ω. The QSW-6200 back panel has one grounding connector.
Figure 2-1 Grounding of the QSW-6200
QSW-6200 Series Switch Hardware Installation and Reference Guide 28
www.qtech.ru
2.2.5 Lightning Resistance
When the AC power cable is imported outdoors and directly connected to the power port of the switch, lightning
preventing wires should be adopted to prevent the switch from being hit by lightning shocks. The lightning preventing
wires can be fixed on the cabinet, work station, or the equipment room’s wall through line buckles and screws. In
applications, the AC current first enters the lightning preventing wires and then the switch.
The lightning preventing wires are not provided and should be purchased by users as required. For the usage of
lightning preventing wires, refer to their manuals.
2.2.6 EMI
All kinds of interference, from inside or outside of the device or application system, create impacts on the device by
transmission of capacity coupling, inductance coupling and electromagnetic waves.
Electromagnetic interference can be divided into two categories by transmission types, namely i.e. radiated interference
and conducted interference.
Power, normally RF power, transmitted from a device through space to a sensor is called radiated interference. The origin
of the interference source can either be part of or a unit separated electrically from the interfered system. Conducted
interference is transmitted through magnetic wires or signal cables from the source origin to sensors. Generally,
conducted interference affects the power supply of a device and can be controlled by a wave filter. Given that radiated
interference can interrupt any signal paths of the device, it is difficult to shield the device from such interference.
The AC power supplying system is the TN system. The single-phase three-wire socket with protecting grounding
must be used as the socket for the power supply to enable the device’s upper filter circuit to effective filter the
power interface.
The switch should be far from high-power radio transmitting stations, radar stations and high-frequency and
large-current devices.
Electromagnetic shielding methods should be applied when necessary, such as using the shielded cable as the
interface cable.
Cables must be connected to interfaces inside the room to prevent damage to the device’s signal ports caused
QSW-6200 Series Switch Hardware Installation and Reference Guide 29
www.qtech.ru
by over-voltage and over-current generated by thunder and lightning.
2.3 Precautions for Fiber Connections
Before you connect the fibers, check that the optical connector type and fiber type match the optical interface type used. In
addition, 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.

When the QSW-6200 is running, users can monitor the status of host and each module by inspecting corresponding
LEDs.
When the system status LED is red, it means the system has a fault, in which case you can determine and
eliminate the fault by viewing with the management software.
When the system status LED is yellow, it means the system temperature exceeds the alarm temperature,
affecting the system operation performance. However, the system can continue running. In this case, you can
determine and eliminate the fault by viewing with the management software.
When the system status LED is red or blinking, it indicates a failure, in which case you need to find out the cause,
and turn off the power when necessary.
When power status LED is yellow, it means that the power is not enough to support the host and expansion
modules, in which case you should apply RPS modules.
When the power status LED is red, check whether or not the power cable is in place and operational; if not
problem, it means the power supply is faulty, in which case you should replace it promptly.
When the LED of expansion modules is blinking or red, it means the expansion modules are faulty, in which case
you should plug and check the modules.
The fast green blinking (10Hz) state of the system status LED is used to locate a switch, which should be

Installing AC Power Arrester (lightning protection cable row)
The external lightning protection cable row shall 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 lightning protection cable row is fixed on the cabinet, operating table or the wall in the machine room using the line
buttons and screws.
Figure B-1 Schematic Diagram for the Power Arrester
The power arrester is not provided and the user shall purchase it to address the practical requirement.
Precautions for installation:
Make sure that the PE terminal of the power arrester has been well-grounded;
After connecting the switch AC power plug to the socket of the power arrester (lightning protection socket),
lightning 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, you shall check what the reason is, poor grounding connection
or the reversed connection of the Null and Live lines: 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 shall be reversed; if the LED is still Red, it is confirmed that the arrester PE terminal has not been
grounded.

Installing the Ethernet Port Arrester
During the switch usage, the Ethernet port arrester shall 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, Diagonal pliers
Installation Steps:
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 shall be
as close to the grounding terminal of the switch.
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.
Use the multimeter to check whether the grounding line for the arrester is in good contact with the switch
grounding terminal and the framework.
According to the description on 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 observe whether the LED on the borad is
normal or not.
Use the nylon button to bundle the power cables.
Figure B-2 Schematic Diagram for the Ethernet port Arrester Installation
The Ethernet port arrester is only for the 10M/100M copper Ethernet ports with the RJ-45 connector;
The Ethernet port arrester is not provided, the user can purchase them to address their own pratical requirements.

For the detailed information during the arrester installation, please refer to Ethenet Port Arrester Hardware Installation
Guide, which contains the technical specification and the maintenance and installation of the arrester.
You may pay attention to the following conditions during the actual installation to avoid influencing the performance of the
Ethernet port arrester:
Reversed direction of the arrester installation. You shall connect the external network cable to the “IN” end and
connect the switch Ethernet port to the “OUT” end.
Poor arrester grounding. The length of the grounding line should 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 condition after the
grounding.
Incomplete arrester installation. If there is more than one port connected to the peer device on the switch, it
needs to install the arresters on all connection ports for the purpose of the lightning protection.

Addition C Cabling Recommendations
When QSW-6200 series switches are installed in standard 19-inch racks, route cable bundles upward or downward along
the sides of the rack depends on the actual situation in the equipment room. All cable connectors should be placed at the
bottom of the rack rather than be exposed outside of the cabinet. Power cords should be routed upward or downward
beside the rack close to the location of the DC power distribution cabinet, AC power outlet, or lightning protection box.
Required Minimum Cable Bend Radius
The minimum bend radius of a power, communication or flat cable should be 5 times the overall diameter of the
cable. If the cable is constantly bent, plugged or unplugged, the bend radius should be 7 times the overall
diameter.
The minimum bend radius of a coaxial cable should be 7 times the overall diameter of the cable. If the cable is
constantly bent, plugged or unplugged, the bend radius should be 10 times the overall diameter.
The minimum bend radius of a high-speed cable, such as an SFP+ cable should be 5 times the overall diameter
of the cable. If the cable is constantly bent, plugged or unplugged, the bend radius should be 10 times the overall
diameter.
Required Minimum Fiber Bend Radius
The diameter of a fiber tray to hold fibers cannot be less than 25 times the diameter of the fiber.
When moving an optical fiber, the bend radius of the fiber should be equal to or greater than 20 times the
diameter of the fiber.
During cabling of an optical fiber, the bend radius of the fiber should be equal to or greater than 10 times the
diameter of the fiber.
Precautions for Cable Bundling
Before bundling cables, correctly mark labels and stick the labels to cables where appropriate.
Cables should be neatly and properly bundled, as shown in Figure C-1.

Figure C-1 Bundling Cables
Route and bundle power, signal, ground cables separately. When the cables are close to each other, cross them.
When power cables run parallel to signal cables, the distance between them must b
All cable trays and their accessories shall be smooth and free from sharp edges.
Holes in metal, through which cables pass shall have smooth, well-rounded surfaces or 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 C-2.
Figure C-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 otherwise cause the wires inside to break, as shown in Figure C-3.

Figure C-3 Do Not Tie Cable Ties within the Bend
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 debugging.
Do not bind power cords to the rails for moving parts.
Leave a certain 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 the excess cable length shall 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 shall be tightened and prevented from loosening, as
shown in Figure C-4.
