08 ago. 2025 - Safety Precautions for FS Switches Mainly Applicable to FS Commercial Switches Preface Audience This document is for network engineers responsible for installing and maintaining FS switches. Experience with network equipment installation and maintenance is required. 1 Precautions for Safe Use 1.1 General Safety Keep the chassis clean and dust-free. Do not place the equipment in walking areas. Do not wear loose clothes, ornaments, or any other things that may be hooked by the chassis during installation and maintenance. Cut off all power supplies and unplug all power cords before installing or dismantling the chassis. Prevent the switch from being frequently handled. Cut off all power supplies and unplug all power cords before moving or handling the switch. Keep balance and prevent personal injuries when handling the switch. Do not hold the handle of the power module or the fan module when moving the switch. Otherwise, it may cause equipment damage or even personal injury. Remove the fan modules and the power modules before handling the equipment. Install the equipment where it is not likely to be moved. 1.2 Installation Environment Requirements FS switches (excluding industrial ethernet switches) must be installed indoors. In order to ensure normal operation and prolonged service life, the installation site must meet the following requirements. 1.2.1 Cabinet Installation Before installing the FS switches in a cabinet, make sure that the cabinet meets the following requirements: Install the switch in an open cabinet. If the switch is installed in a closed area, ensure that it has a good ventilation system. Confirm that the cabinet is sturdy enough to support the weight of the FS switches and accessories. Maintain a clearance around the chassis in the cabinet for heat dissipation. The cabinet is properly grounded. 1.2.2 Ventilation Keep a minimum clearance of 200mm (7.87 in.) around the FS switches for air circulation. After various cables are connected, bundle the cables or route them over the cable management bracket to avoid blocking air inlets. 1.2.3 Temperature and Humidity To ensure the normal operation and prolonged service life of the FS switches, 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 time may damage the switches. In an environment with high relative humidity, the insulating material may have poor insulation or even leak electricity. Sometimes also prone to changes in the mechanical properties of materials, metal parts rust and other phenomena. In an environment with low relative humidity, static electricity is prone to occur and damage the internal circuits of the equipment. Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the switch and severely affecting its service life. The ambient temperature and humidity of the equipment are measured at the point that is 1.5m (59.06 in.) above the floor and 0.4m (15.75 in.) before the rack when there is no protective plate in the front or at the back of the rack. 1.3 Electrical Safety 1.3.1 Grounding A proper grounding system is the basis for stable and reliable operation of FS switches and is indispensable for preventing lightning strikes and resisting interference. Carefully check the grounding conditions at the installation site according to the grounding specifications, and complete grounding properly based on the actual situation. Safety Grounding The switch using AC or high-voltage DC power supply must be grounded by using the green and yellow grounding cable. Otherwise, when the high voltage circuit inside the switch has a grounding fault, an electric shock may occur. The building should provide a protective ground connection to ensure that switches are connected to the protective ground. Lightning Grounding The lightning protection system of the facility is a separate system consisting of a lightning rod, a lower conductor and a connector connected to the grounding system. This grounding system is usually shared with the ground used as the power supply reference ground and the yellow-green safety ground. Lightning discharge grounding is only for facilities, equipment does not have this requirement. For lightning protection, see Requirements for Lightning Proof Grounding. EMC Grounding Grounding requirements for EMC design purposes include: shield grounding, filter grounding, noise and interference suppression, and level referencing. These form the combined grounding requirements. Grounding resistance is required to be less than 1 Ω. There is one ground terminal on the back of the FS switch chassis, which is indicated by a conspicuous warning label. Figure 1 EMC Grounding image.png 1.4 Battery Safety 1.4.1 Basic Requirements Observe local regulations and specifications during electrical operations. Only personnel with relevant 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. Learn about the position of the indoor emergency power switch before installation. Cut off all power when an accident occurs. Do not maintain the equipment that is powered-on alone. Check the equipment carefully before shutting down the power supply. Do not place the equipment in a wet position, and keep the chassis away from liquid. Irregular and incorrect electrical operation may cause accidents such as fire or electric shock, and lead to serious and fatal injuries to the human body and equipment. Direct or indirect contact with high voltage and mains electricity through wet objects may pose a fatal risk. If the FS switch system has more than one input power source, be sure to disconnect all power cords before shutting down the system. 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 1.75mA, and the leakage current of the system totals 28mA. A leakage protector with 30 mA rated action current supports less than 9 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 30mA rated action current supports no more than 8 power supplies. In this case, the 16 power supplies in the system require at least two leakage protectors with 30mA rated action current and each leakage protector supports 8 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 30mA rated leakage action current as an example. The rated leakage non-action current shall be 15mA. When the leakage current is below 15mA, 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 30mA (human body safety current is 30mA). When twice of the total leakage current of the system is greater than 30mA, the system must be equipped with two or more leakage protectors. 1.4.2 Requirements for Rechargeable Batteries If a rechargeable battery is used, pay attention to the following precautions: If discoloration, deformation, overheating, or any other abnormality occurs, replace the battery before continuing with usage, charging or storage. Tighten battery cables or copper bars using the torque specified in the battery documentation. Insecure connection of battery bolts may cause excessive voltage drop or even overcurrent leading to battery overheating. If the battery temperature exceeds 60°C (140 °F), check for and promptly handle any leakage. If the electrolyte overflows, take proper measures promptly. When removing or moving the battery with spilled electrolyte, be careful with the electrolyte that can cause potential injury. If any electrolyte spills, use NaHCO(3) or Na(2)CO(3) to neutralize and absorb it. After batteries are installed, ensure that the fuse or circuit breaker is disconnected before powering the system. This avoids battery damage caused by power discharge in case of long-term power-off. Improper usage of lead-acid batteries will cause the release of flammable gas. Ensure that batteries are kept in a well-ventilated area and take preventive measures against fire. The battery should not be exposed to high temperature environments or around heat generating equipment such as sunlight, heaters, microwave ovens, ovens or water heaters. Battery overheating may cause an explosion. 1.4.3 Requirements for Non-Rechargeable Batteries If the equipment uses a dry battery or non-rechargeable lithium battery, consider the following: If discoloration, deformation, overheating, or any other abnormality occurs, replace the battery before continuing with usage or storage. Do not attempt to replace non-removable, built-in batteries. Doing so may damage the batteries or the equipment. Batteries must be replaced by an authorized service center. Do not throw the battery into the fire. Otherwise, the battery will catch fire and explode. 1.5 Radiation Safety 1.5.1 Electromagnetic Field Exposure Various interference sources, whether from outside the equipment or application system, or from within, are capacitive coupling, inductive coupling, electromagnetic wave radiation and other conductive ways to produce effects on the equipment. Electromagnetic interference is divided into two categories: radiation interference and conducted interference, which is determined by the type of propagation path. When the energy emitted by a device, usually RF energy, reaches a sensitive device through space, it is called radiated interference. The interference source can be both a part of the interfered system and a completely electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection between the source and the sensitive component, along the 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. Take effective measures for the power system to prevent interference from the electric grid. Keep the running position of the switch as far as possible from the grounding device of the power equipment or the anti-lightning grounding device. Keep the device away from high-power radio transmitters, radar transmitting station, and high-frequency large-current device. Take measures to isolate static electricity. 1.5.2 Laser Safety Among the modules supported by the FS switches, many optical transceivers are Class I laser products. Precautions: When an optical transceiver works, ensure that the port has been connected with a fiber or covered by a dust cap to keep out dust and prevent it from burning your eyes. Do not look into any optical port. Do not approach or stare at any fiber port under any circumstances, as this may cause permanent damage to your eyes. 1.6 Hardware Maintenance 1.6.1 Expansion Modules Maintenance In the event of a failure and the need to replace an expansion module, the expansion module must be installed and disassembled in accordance with the instructions for operation. 1.6.2 Cooling System Maintenance If a fan module fails, an alarm will be generated. Replace the faulty fan module. Tighten the captive screws. 1.6.3 Power Supply Maintenance When a power module is faulty, unplug the power cord, replace the power module, and plug the power cord again. 1.6.4 Replacing Lithium Battery The built-in lithium batteries can support the real time clock of the FS switches without external power supply. To replace lithium batteries, please contact FS technical support personnel. The technical support personnel will select lithium batteries of the same specifications for replacement. 1.6.5 Replacing Fuses To replace fuses, please contact FS technical support personnel. The technical support personnel will select fuses of the same specifications for replacement. 2 Environmental Requirements for Device Operation 2.1 Environmental Requirements for an Equipment Room Ensure that the installation environment complies with equipment specifications, including voltage, temperature, humidity, altitude, degree of pollution, overvoltage category, and waterproofing and dustproofing classification. Avoid flammable, explosive gas or smog environments. Keep the installation site free of acidic, alkaline or other corrosive gases. Keep the equipment away from sources of heat or fire, such as the electric heater, microwave oven, oven, water heater, fireplace, candle or other heat generators. Heat may cause the equipment to catch fire or its housing to melt. Do not obscure or cover running equipment with flammable materials such as paper or fabric. This hampers heat dissipation and can cause the equipment to catch fire or its housing to melt. This equipment (or system) must be installed or used in restricted areas. Do not block air vents when the equipment is running. Maintain air vents away from the wall or other objects as required in the operation guide. 2.2.1 Requirements for Selecting a Site for an Equipment Room Communication equipment should be in a good operating environment. When designing a project, consider the communication network planning and technical requirements of the equipment. Also consider hydrographic, geological, seismic, power supply, and transportation factors. Construction, structure, heating and ventilation, power supply, lighting and fire-proof construction of the equipment room should be designed by specialized construction designers to suit the environmental requirements of devices. The equipment room should also follow local regulations concerning the industrial construction, environmental protection, fire safety, and civil air defense. Construction must conform to government standards, regulations, and other requirements. The equipment room should be located in a place free from high temperature, dust, toxic gases, explosive materials, or unstable voltage. Keep the equipment room away from significant vibrations or loud noises, as well as power transformer stations. The specific requirements for selecting a site for an equipment room are as follows: The equipment room should be at least 5 km away from heavy pollution sources, such as the smelter works, coal mine, and thermal power plant. The equipment room should be at least 3.7 km away from medium pollution sources, such as the chemical factory, rubber factory, and electroplating factory. The equipment room should be at least 2 km away from light pollution sources, such as the food factory and leather plant. If these pollution sources are unavoidable, the equipment room should be located on the windward side of the pollution sources perennially with advanced protection. Do not build the equipment room in the proximity of livestock farms. Otherwise, the equipment room should be located on the windward side of the pollution source perennially. The previous livestock house or fertilizer warehouse couldn't be used as the equipment room. The equipment room should be away from the residential area. Otherwise, the equipment room should meet the construction standard in terms of noise. Keep the door and the window closed to make the equipment room sealed. The steel door is recommended for soundproofing. Make sure there are no cracks or holes on the wall and floor. If there are cable entries on 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. Make sure that the air vents of the equipment room are away from the sewage pipe, septic tank, and sewage treatment tank. Keep the equipment room under positive pressure to prevent corrosive gas from entering the equipment room to corrode components and PCBs. Keep the equipment room away from industrial boilers and heating boilers. The equipment room had better be on the second floor or above. Otherwise, the equipment room floor should be 600mm higher than the highest flood level ever recorded. The equipment room should be at least 3.7 km away from the sea or salt lake. Otherwise, the equipment room must be sealed, with air conditioner installed for temperature control. Saline soil can not be used for construction. Otherwise, you should select devices with advanced protection against severe environments. The equipment room should be firm enough to withstand severe weather conditions such as wind storms and heavy rain as well as away from dust. If dust is unavoidable, keep the door and window away from the pollution source. Keep the air conditioner from blowing wind straight toward the equipment or blowing water drops from the window or air vent toward the equipment. Sulfur-containing materials are forbidden. 2.1.2 Equipment Room Layout An equipment room usually contains mobile switching equipment, telecommunications equipment, power supply equipment, and other auxiliary equipment. To ensure easy maintenance and management, place the equipment in different rooms. Figure 2 shows the layout of the equipment room. Figure 2 Layout of the Equipment Room image.png The general layout principles of the equipment room are as follows: It should meet requirements for laying out and maintaining communication cables and power cables. It should reduce the cabling distance, which facilitates cable maintenance, reduces potential communication faults, and maximizes efficiency. 2.1.3 Construction Requirements for the Equipment Room Table 1 describes the construction requirements for the equipment room. Figure 3 Internal Partition Wall Inside the Equipment Room image.png 2.1.4 Equipment Room Environment Dust on devices may cause electrostatic discharge and result in poor contact for connectors or metal connection points. This problem can shorten the life span of devices and cause faults. The equipment room must be free from explosive, conductive, magnetically-permeable, and corrosive dust. Table 2 lists the requirement for dust concentration in the equipment room. Take the following measures to meet the requirements: Use dustproof materials for ground, wall, and ceiling construction. Use screens on the door and windows facing outside. The outer windows should be dust-proof. Clean the equipment room and clean devices' air filters monthly. Wear shoe covers and ESD clothing before entering the equipment room. 2.2 Requirements for Corrosive Gases The room should be free from dusts and corrosive gases, such as SO(2), H(2)S, and NH(3). Table 3 lists the requirements for the corrosive gas concentration. Take the following measures to meet the requirements: Avoid constructing a room near a place where the corrosive gas concentration is high, such as a chemical plant. Ensure the air intake vent of the room is in the prevailing upwind direction from any pollution source. Place batteries in different rooms. A professional service should monitor the corrosive gas conditions regularly. 2.3 Requirements for ESD Prevention The absolute value of electrostatic voltage must be less than 1000V. Take the following measures to meet this requirement: Train operators about ESD prevention. Keep the correct humidity level in the equipment room to reduce the impact of static electricity. Lay out an ESD floor in equipment rooms. Wear ESD shoes and clothing before entering the equipment room. Use ESD tools, such as wrist straps, tweezers, and pullers. Ground all conductive materials in the room, including computer terminals. Use ESD worktables. Keep non-ESD materials (such as common bags, foam, and rubber) at least 30cm (11.81in.) away from boards and ESD-sensitive components. 2.4 Electromagnetism Requirements for the Equipment Room All interference sources, inside or outside the equipment room, can cause equipment problems with capacitive coupling, inductive coupling, electromagnetic wave radiation, and common impedance (including grounding system) coupling. Prevent interference using these approaches: Take effective measures against electrical interference from the power supply system. Do not use the working ground of the equipment as the same ground for surge protection. Separate them as far as possible. Keep the equipment far away from high-power radio transmitters, radar units, and high-frequency and high-current equipment. Use electromagnetic shielding if necessary. 2.5 Requirements for Lightning Proof Grounding Table 4 lists the requirements for lightning proof grounding.
