dust cap, to keep out dust and avoid burning your eyes.
When the optical module is working, do not pull out the fiber cable and stare into the transceiver interface or you may
hurt your eyes.
Do not stare into any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.2 Installation Site Requirements
To ensure the normal working and a prolonged durable life of the equipment, 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.

QSW-4600 Series Switch Hardware Installation and Reference Guide 12
www.qtech.ru
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.
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
A sufficient space (at least 10 cm distances from both sides and the back plane of the cabinet) should be reserved at the
ventilation openings to ensure the normal ventilation. After various cables have been connected, they should be arranged
into bundles or placed on the cabling rack to avoid blocking the air inlets. It is recommended to clean the switch at regular
intervals (like once every 3 months). Especially, avoid dust from blocking the screen mesh on the back of the cabinet.
2.2.2 Temperature and Humidity
To ensure the normal operation and prolong the service life of QSW-4600 series switch, you should 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 high relative humidity, the insulating material may have bad insulation or even leak electricity.
Sometimes the materials may suffer from mechanical performance change and metallic parts may get rusted.
In an environment with low relative humidity, however, the insulating strip may dry and shrink. Static electricity may
occur easily and endanger the circuit on the equipment.
In an environment with high temperature, the equipment is subject to even greater harm, as its performance may
degrade significantly and various hardware faults may occur.
Therefore, the ambient temperature and humidity of the QSW-4600 series must meet the requirements listed in Table 2-1:

QSW-4600 Series Switch Hardware Installation and Reference Guide 13
www.qtech.ru
Table 2-1 Temperature and Humidity Requirements of the QSW-4600 Series Switch
Temperature
Relative Humidity
0 ºC to 50ºC
10% to 90%
The requirements for the sampling site of the temperature and humidity in the operating environment of the device
are as follows:
There is no protective plate at the front or back of the equipment rack.
The vertical height is 1.5 m above the floor.
The distance from the front panel of the equipment is 0.4 m.
2.2.3 Cleanness
Dust poses a severe 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 useful life of the equipment, but also causing communication faults.
Table 2-2 shows the requirements for the dust content and granularity in the equipment room.

2.2.4 Grounding
A good grounding system is the basis for the stable and reliable operation of the QSW-4600 series switch. It is the chief
condition 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 operations properly as required.
Effective grounding of the switch is an important guarantee for lightning protection and interference resistance.
Therefore, connect the grounding line of the switch properly.
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.
The building must provide 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, they should 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 the installation of the device, make sure that ground connection 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 lightning protection system of a facility is an independent system that consists of the lightning rod, download
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, irrelevant to the equipment.
EMC Grounding
The grounding 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 resistance of earth wires should
be less than 1 ohm. The QSW-4600 series switch back plane is reserved with one grounding pole, as shown in Figure 2-1.
Figure 2-1Grounding of QSW-4600

QSW-4600 Series Switch Hardware Installation and Reference Guide 15
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 QSW-4600 series switch,
lightning line bank should be adopted to prevent the switch from being hit by lightning shocks. Usage of the lightning line
bank: Connect the mains supply AC cable to the lightning line bank. Then, connect the switch to the lightning line bank.
This can help to 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 users as required.
For the usage of lightning line banks, refer to their related manuals.
2.2.6 EMI
Electro-Magnetic Interference (EMI), from either outside or inside the equipment 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 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 sensitive component, along which cable the interference conducts from one unit to another. 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 equipment and is difficult to shield.
For the AC power supply system TN, single-phase three-core power socket with protective earthing conductors (PE)
should be adopted to effectively filter out interference from the power grid through the filtering circuit.
The grounding device of the switch must not be used as the grounding device of the electrical equipment or
anti-lightning grounding device. In addition, the grounding device of the switch must be deployed far away from the
grounding device of the electrical equipment and anti-lightning grounding device.
Keep the equipment away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
Measures must be taken to shield static electricity.
Interface cables should be laid inside the equipment room. Outdoor cabling is prohibited, avoiding damages to
device signal interfaces caused by over-voltage or over-current of lightning.
