with the high voltage power supply or human contact through damp objects can be fatal.l Unspecified or unauthorized high voltage operations could result in fire or electric shock, or

both.

ThunderstormThe requirements apply only to wireless base stations or devices with antennas and feeders.

DANGERDo not perform operations on high voltage, AC power, towers, or backstays in stormy weatherconditions.



4

High Leakage Current

WARNINGBefore powering on a device, ground the device. Otherwise, the safety of humans and the devicecannot be ensured.

If a high leakage current mark is labeled near the power connector of the device, you mustconnect the PGND terminal on the shell to the ground before connecting the device to an A/Cinput power supply. This is to prevent the electric shock caused by leakage current of the device.

Power Cables

DANGERDo not install or remove the power cable with a live line. Transient contact between the core ofthe power cable and the conductor may generate electric arc or spark, which may cause fire oreye injury.

l Before installing or removing power cables, you must power off the device.

l Before connecting a power cable, you must ensure that the label on the power cable iscorrect.

Device with Power On

DANGERInstalling or removing a device is prohibited if the device is on.

Short Circuits

When installing and maintaining devices, place and use the associated tools and instruments inaccordance with regulations to avoid short-circuits caused by metal objects.

CAUTIONTo avoid short-circuits when using a tool (such as a screwdriver), do not place the tool on theventilation plate of the subrack.



5

CAUTIONPrevent any screws from dropping into the subrack or chassis to avoid short-circuits.

Fuse

WARNINGIf the fuse on a device blows, replace the fuse with a fuse of the same type and specifications toensure safe operation of the device.

Electrostatic Discharge

CAUTIONThe static electricity generated by the human body may damage the electrostatic sensitivecomponents on the board, such as the large-scale integrated circuit (LSI).

l The human body can generate static electromagnetic fields in the following situations:physical movement, clothing friction, friction between shoes and the ground, plastics inthe hand. Such static electromagnetic effects can remain for an appreciable time.

l Before operating a device, circuit boards, or ASICs, wear an ESD wrist strap that is properlygrounded. The ESD wrist strap can prevent the electrostatic-sensitive components frombeing damaged by the static electricity in the human body.

l Sodium carbonate (Na2CO3)

In the event of acid overflow or spillage, neutralize the acid and clean it up as recommended bythe battery manufacturer and any local regulations for acid disposal.

If a person contacts battery electrolyte, clean the skin that contacts the battery electrolyteimmediately by using water. In case of a severe situation, the person must be sent to a hospitalimmediately.

1.6 RadiationThis topic describes safety precautions for electromagnetic exposure and lasers.

1.6.1 Safe Usage of Optical FibersThe laser beam can cause damage to your eyes. Hence, you must exercise caution when usingoptical fibers.

DANGERWhen installing or maintaining an optical interface board or optical fibers, avoid direct eyeexposure to the laser beams launched from the optical interface board or fiber connectors. Thelaser beam can cause damage to your eyes.

Cleaning Fiber Connectors and Optical Interfaces

CAUTIONIf fiber connectors or flanges are contaminated, optical power commissioning is seriouslyaffected. Therefore, the two endfaces and flange of every external fiber must be cleaned beforethe fiber is led into the equipment through the ODF for being inserted into an optical interfaceon the equipment.

The fiber connectors and optical interfaces of the lasers must be cleaned with the followingspecial cleaning tools and materials:

l Special cleaning solvent: It is preferred to use isoamylol. Propyl alcohol, however, can alsobe used. It is prohibited that you use alcohol and formalin.

l Non-woven lens tissuel Special compressed gasl Cotton stick (medical cotton or long fiber cotton)l Special cleaning roll, used with the recommended cleaning solventl Special magnifier for fiber connectors

For cleaning steps, see Appendix "Inspecting and Cleaning the Fiber-Optical Connectors" in theOptiX OSN 3500 Intelligent Optical Transmission System Troubleshooting.

Replacing Optical FibersWhen replacing an optical fiber, cover the fiber connector of the unused optical fiber with aprotective cap.

Connecting Optical Fibersl Use an attenuator if the optical power is excessively high. A high received optical power

damages the optical interface.l Directly connect an attenuator to a slanting optical interface. Install the attenuator on the

IN port instead of the OUT port.l Do not directly connect an attenuator to the level optical interface. Use the optical

distribution frame (ODF) to connect an attenuator to a level optical interface.

1.6.2 Electromagnetic ExposureThis topic describes safety precautions for electromagnetic exposure.

WARNINGHigh-intensity RF signals are harmful to the human body.

If multiple transmit antennas are installed on a tower or backstay, you must request the relevantpersonnel to shut down the transmit antenna before they install or maintain the antenna locally.

During the operation, the base transceiver station (BTS) may generate electromagnetic radiation(namely, radiation harm). Before installing and operating the BTS equipment, read the guidelinesto ensure safe operations. When installing the BTS equipment, obey the local rules andregulations.

1.6.3 Forbidden AreasThe topic describes requirements for a forbidden area.

l The site of the antenna must be far away from the area where the electromagnetic radiationis beyond the specified range and the public cannot reach.

l Before entering the area where the electromagnetic radiation is beyond the specified range,the associated personnel must learn about the area and shut down the electromagneticradiator. The area where the electromagnetic radiation is beyond the specified range, if any,should be within 10 meters away from the antenna.

l A physical barrier and an eye-catching warning flag must be available in each forbiddenarea.

1.6.4 LaserThis topic describes safety precautions for lasers.

WARNINGWhen handling optical fibers, do not stand close to, or look into the optical fiber outlet directlywithout eye protection.

Laser transceivers are used in the optical transmission system and associated test tools. The lasertransmitted through the bare optical fiber produces a small beam of light, and thus it has veryhigh power density and is invisible to human eyes. When a beam of light enters eyes, the eyesmay be damaged.

In normal cases, viewing an un-terminated optical fiber or a damaged optical fiber without eyeprotection at a distance greater than 150 mm does not cause eye injury. Eye injury may occur,however, if an optical tool such as a microscope, magnifying glass, or eye loupe is used to viewan un-terminated optical fiber.



11

Safety Instructions Regarding LasersTo avoid laser radiation, obey the following instructions:

l All operations should be performed by authorized personnel who have completed therequired training courses.

l Wear a pair of eye-protective glasses when you are handling lasers or fibers.l Ensure that the optical source is switched off before disconnecting optical fiber connectors.l Do not look into the end of an exposed fiber or an open connector when you are not sure

whether the optical source is switched off.l Use an optical power meter to measure the optical power and ensure that the optical source

is switched off.l Before opening the front door of an optical transmission device, ensure that you are not

exposed to laser radiation.l Do not use an optical tool such as a microscope, a magnifying glass, or an eye loupe to

view the optical connector or fiber that is transmitting optical signals.

Instructions Regarding Fiber HandlingRead and abide by the following instructions before handling fibers:

l Only trained personnel are permitted to cut and splice fibers.l Before cutting or splicing a fiber, ensure that the fiber is disconnected from the optical

source. After disconnecting the fiber, cap to the fiber connectors.

1.6.5 MicrowaveWhen installing and maintaining the equipment of Huawei, follow the safety precautions ofmicrowave to ensure the safety of the human body and the equipment.

WARNINGStrong radio frequency can harm the human body.

When installing or maintaining an aerial on the tower or mast that is installed with multipleaerials, switch off the transmitter in advance.

1.7 Working at HeightsThis topic describes safety precautions for working at heights.

WARNINGWhen working at heights, be cautious to prevent objects from falling down.

The requirements for working at heights are as follows:



12

l The personnel who work at heights must be trained.l Carry and handle the operating machines and tools with caution to prevent them from falling

down.l Safety measures, such as wearing a helmet and a safety belt, must be taken.l Wear cold-proof clothes when working at heights in cold areas.l Check all lifting appliances thoroughly before starting the work, and ensure that they are

intact.

1.7.1 Hoisting Heavy ObjectsThis topic describes the safety precautions for hoisting heavy objects that you must follow wheninstalling, operating, and maintaining Huawei devices.

WARNINGWhen heavy objects are being hoisted, do not walk below the cantilever or hoisted objects.

l Only trained and qualified personnel can perform hoisting operations.l Before hoisting heavy objects, check that the hoisting tools are complete and in good

condition.l Before hoisting heavy objects, ensure that the hoisting tools are fixed to a secure object or

wall with good weight-bearing capacity.l Issue orders with short and explicit words to ensure correct operations.l Ensure that the angle between the two cables is less than or equal to 90 degrees during the

lifting, as shown in Figure 1-4.

1.8 Mechanical SafetyThis topic describes safety precautions for drilling holes, handling sharp objects, operating fans,and carrying heavy objects.

Drilling Holes

WARNINGDo not drill holes on the cabinet without prior permission. Drilling holes without complyingwith the requirements affects the electromagnetic shielding performance of the cabinet anddamages the cables inside the cabinet. In addition, if the scraps caused by drilling enter thecabinet, the printed circuit boards (PCBs) may be short-circuited.

l Before drilling a hole on the cabinet, remove the cables inside the cabinet.

l Wear an eye protector when drilling holes. This is to prevent eyes from being injured bythe splashing metal scraps.

l Wear protection gloves when drilling holes.

l Take measures to prevent the metallic scraps from falling into the cabinet. After the drilling,clean up the metallic scraps.

Sharp Objects

WARNINGWear protection gloves when carrying the device. This is to prevent hands from being injuredby the sharp edges of the device.

Fansl When replacing parts, place the objects such as the parts, screws, and tools properly. This

is to prevent them from falling into the operating fans, which damages the fans or device.

l When replacing the parts near fans, keep your fingers or boards from touching operatingfans before the fans are powered off and stop running. Otherwise, the hands or the boardsare damaged.

Carrying Heavy Objects

Wear protection gloves when carrying heavy objects. This is to prevent hands from being hurt.



16

WARNINGl The carrier must be prepared for load bearing before carrying heavy objects. This is to prevent

the carrier from being strained or pressed by the heavy objects.l When you pull a chassis out of the cabinet, pay attention to the unstable or heavy objects on

the cabinet. This is to prevent the heavy objects on the cabinet top from falling down, whichmay hurt you.

l Generally, two persons are needed to carry a chassis. It is prohibited that only one personcarries a heavy chassis. When carrying a chassis, the carriers should stretch their backs andmove stably to avoid being strained.

l When moving or lifting a chassis, hold the handles or bottom of the chassis. Do not holdthe handles of the modules installed in the chassis, such as the power modules, fan modules,and boards.

1.9 Other PrecautionsThis topic describes safety precautions for removing and inserting boards, binding signal cables,and routing cables.

Removing and Inserting a Board

CAUTIONWhen inserting a board, wear an ESD wrist strap or ESD gloves, and handle the board gently toavoid distorting pins on the backplane.

l Slide the board along the guide rails.l Do not contact one board with another to avoid short-circuits or damage.l When holding a board in hand, do not touch the board circuits, components, connectors,

or connection slots of the board to prevent damage caused by ESD of the human body tothe electrostatic-sensitive components.

Binding Signal Cables

CAUTIONBind the signal cables separately from the high-current or high-voltage cables.

Routing CablesIn the case of extremely low temperature, heavy shock or vibration may damage the plastic skinof the cables. To ensure the construction safety, comply with the following requirements:



17

l When installing cables, ensure that the environment temperature is above 0°C.l If the cables are stored in a place where the ambient temperature is below 0°C, transfer

them to a place at room temperature and store the cables for more than 24 hours beforeinstallation.

Area for the Cable-Routing ChannelAn isolating plate is available in the cable-routing channel to divide the cable-routing channelinto the upper and lower layers. In this case, fiber jumpers can be protected, and route powercables and signal cables can be routed separately.

To route cables, comply with the following rules:

l If no power cables are routed in the cable-routing channel, route fiber jumpers at the upperlayer, and route network cables at the lower layer.

l If certain power cables are routed in the cable-routing channel, route fiber jumpers andnetwork cables at the upper layer, and route power cables at the lower layer.

l If certain E1 cables are routed in the cable-routing channel, route fiber jumpers at the upperlayer, and route network cables at the lower layer.

General Instructions for Cable RoutingThe cables of the equipment are routed as follows:l The external power cables, grounding cables, and signal cables of the cabinet are routed

separately with the spacing of more than three centimeters.l After the power cables of the subrack are bound on to the cable distribution frame, they are

routed to the rear part of the two side panels of the cabinet, and then routed to the powerbox along the rear part of the side panels.

l The power cables of the IF board connect the IF power board to the IF board. If the IFpower cable is redundant in the cable-routing channel, bundle the remaining part of the IFpower cable on the vertical column or at the cable-routing area on the side of the cabinet.

l The method of routing the IF cables is the same as the method of routing the signal cables.l In the case of upward cabling, the signal cables of the upper subrack are led out from the

cable-through holes in the top middle of the cabinet, and the signal cables of the lowersubrack are led out from the cable-through holes on the two sides of the top of the cabinet.

l In the case of upward cabling, the signal cables of the upper and lower subracks are led outfrom the cable-through holes on the two sides of the bottom of the cabinet.

13.2 Checking the Cable InstallationAfter installation, you need to check the necessary items.

The following requirements should be met when the cable installation is completed.

l All cables are bound with proper tightness. The spacing between the cable ties is even, andthe remaining parts of the cable ties are cut off neatly. All cable ties face the same direction,thus keeping the overall appearance nice.

l All cables are arranged smoothly, with no roundabout twists and turns.l When a trough is used for cabling outside the cabinet, do not make the cables overflow the

trough.l Cables shall be secured on the beam of the cabling frame, if such a cabling frame is used

for cabling. They shall be bound neatly in rectangle shape (or in circular shape when thecables are single-cored).

l If need, bend the cables in a radius as large as possible. The cables cannot be bound wherethey are bent.



93

l The -48 V/-60 V cable shall be blue, 0 V cable be black, and PGND cable be yellow/greenor yellow.

l The power cables are connected correctly and firmly.l The diameter of the power cables meets the power distribution requirements.l The external power cables are arranged separately from signal cables, with a space of more

than 3 cm.l The power cables are bent smoothly.l The power cables must be made of an entire piece of copper core, without any joint in the

middle.l Labels for the power cables are filled in and affixed to the cables as required. All labels are

neat and face the same direction.

14 Installing and Routing Fiber Jumpers

About This Chapter

The fiber jumpers are divided into internal fiber jumpers and external fiber jumpers. Internalfiber jumpers are used for connecting optical interfaces within a cabinet. The external fiberjumpers are used for connecting the optical interfaces of a cabinet to the optical interfaces ofother cabinets or peripherals. While external fiber jumpers are used for connecting opticalinterfaces of a cabinet with those of other cabinets or peripherals.

NOTE

For the method of installing and routing fiber jumpers, see the OptiX OSN 3500 Quick InstallationGuide.

14.1 Fiber JumpersThe fiber jumpers are used to connect the optical boards on one subrack with those in othercabinets or other equipment. All fiber jumpers can be transferred by an external opticaldistribution frame (ODF).

About This Chapter

This topic describes how to power on the equipment.

DANGERDo not touch the equipment power supply directly or indirectly through a damp object to preventpersonal injury.

To power on the equipment, perform the following operations.

18.1 Checking Fuse Currents of the Power SupplyThis task is performed to check the supply current of the power supply device and to ensure thefuse current meets the requirements of the OptiX OSN equipment.

18.2 Checking Resistance Between the Power Input Terminals of the DC PDUTest the resistance between the power supply input terminals when the power switch is turnedto the ON side and OFF side. According to the test result, you can check whether the DC PDUworks normally, and whether the cabinet power cable, cabinet PGND cable and DC PDU PGNDcable are connected correctly. This section describes how to test the resistance between the powerinput terminals of the DC PDU and the check criteria.

18.3 Powering on a CabinetIf the cabinet power voltage is abnormal, the OptiX OSN equipment operates in an abnormalmanner or fails to operate. This section describes how to power on the cabinet and test the powervoltage. Perform this task to ensure the voltage of the power supply meets the requirements ofthe OptiX OSN equipment.

18.4 Powering On the SubrackTo power on the subrack is the last step to power on the equipment. To prevent effect caused bymis-installation to powering on the equipment, check the installation and the routing of powercables before powering on the subrack. This section describes how to check the hardwareinstallation.

18.5 Observing the Fan Running Status

OptiX OSN 3500 Intelligent Optical Transmission SystemInstallation Guide 18 Powering on the Equipment


111

After a subrack is switched on, fans start to operate. The fan indicators indicate the working stateof the fans. If the indicator indicates that the fan is faulty, replace the faulty fan in time. Thissection describes how to determine the state of the fan hardware by observing the fan indicators.



112

18.1 Checking Fuse Currents of the Power SupplyThis task is performed to check the supply current of the power supply device and to ensure thefuse current meets the requirements of the OptiX OSN equipment.

PrerequisitesThe power supply device must have been installed and tested.

Tools, Equipment and MaterialsNone

Background InformationThe internal power supply system consists of the PDU and PIU. For details on the mapping rules,see 2.3 Mapping Policies of Power Consumption of the Hardware Description.

If you need to choose a fuse according to the actual configuration, calculate the fuse capacityby using the following formulas:

l -48 V power system: Fuse capacity = (Total power consumption x 1.5)/42l -60 V power system: Fuse capacity = (Total power consumption x 1.5)/52.5

The specifications of fuse capacity in the market are limited. Hence, select the minimum fusecapacity that is higher than the value obtained after the calculation.

Procedure

Step 1 Check the maximum power consumption and fuse current of the OptiX OSN equipment.

Step 2 Compute the fuse current of the power supply device with a joint consideration of the equipmentconfiguration in the equipment room.

NOTE

When considering the fuse current in the equipment room, in addition to the power consumption of theequipment, you need to compute the power consumption of the ODU. That is, the fuse current in theequipment room is not less than the total power consumption of the equipment and ODU.

Step 3 Check if fuse current of the power supply device meets the requirement.

DC power supplygrounding

The working ground of the communication office, that is, the positivepole of the -48 V DC power supply or the negative pole of the +24 Vpower supply, must be led from the local indoor grounding bus. Thegrounding cable must meet the requirement of the maximum load of theequipment. The power supply facilities for the equipment room mustpossess a DC working neutral line, which is introduced from the generalgrounding bus or protection grounding bar of the equipment room.

Equipotentialconnection

All the communication equipment and auxiliary equipment in the roomsuch as the base station, transmission equipment, switching equipment,power supply equipment, and distribution frame must be connected tothe protection ground. The protection grounding of all the equipment inthe communication office must share the same general grounding bar,whereas the protection grounding of the same equipment room must beconnected to the same protection grounding bar. The working groundand protection ground of the communication equipment in the room mustadopt the joint grounding mode. That is, they share the same groundingnetwork. Protection grounding efforts must also be made to the indoorcabling frames, suspended iron supports, equipment rack or chassis,metallic ventilation pipes, and metallic doors and windows.

Generalrequirements forgrounding

The AC neutral line cannot be connected to the protection ground of anycommunication equipment in the equipment room. Make sure that nofusees, switches or other equipment are connected to the groundingcables. All the grounding cables must be as short and straightforward aspossible to prevent the grounding cables from winding.

Groundingresistance

The grounding resistance must be less than 10 ohms. The upper end ofthe grounding body must be 0.7 meter or more underground. In coldareas, the grounding body must be buried in the frozen layer or lower.Monitor the grounding resistance periodically to ensure that thegrounding is always effective.

21.10 Requirements for the Power SupplyThe working power voltage of the OptiX transmission equipment ranges from -38.4 V to -57.6V when the -40 V DC power supply is used or from -48 V to -72 V when the -60 V DC powersupply is used.

The transmission equipment provides a transmission path for communication networks. Hence,its interruption can cause a wide influence. Therefore, the DC power distribution system mustbe protected against power failure and configured with storage batteries. To deal with a long-term power outage, a diesel generator must be equipped as the standby AC power supply for thebackbone transmission equipment. The DC power supply system consists of a storage battery,a primary power supply (rectifier), and a DC power distribution and control panel. This topicdescribes the requirements for the power supply of the equipment.

Storage BatteryA storage battery is an essential component of the DC power distribution system of the OptiXoptical transmission equipment. A storage battery performs the following functions:

l Stabilizes the voltage so that the transmission equipment can work reliably.l Stores the energy. In the case of mains outage, the storage battery can feed power for a

period of time, according to its capacity. Thus, the communication is not interruptedimmediately.

l Filters large capacitors. The storage battery can be used to absorb surge voltage from therectifier and to prevent noise and power frequency interference from getting into thecommunication equipment.

l Shuts down the storage battery automatically. When the voltage of the storage battery dropsto lower than -43 V, the control circuit can automatically shut down the output.

The storage battery of the OptiX optical transmission equipment is charged and discharges undera low and constant voltage. Table 21-7 lists the relevant requirements.

Primary Power Supply (Rectifier)The requirements for the primary power supply are as follows:

l The primary power supplies can operate in parallel, and a current equalizer must existbetween them.

l The primary power supply should be equipped with a current limiter.l The output voltage of the primary power supply should meet the requirement for initial

charging of the storage battery, that is, 2.35 x 24 = 56.4 V DC (when the power supply is-48 V DC).

l A DC voltmeter and an ammeter should be installed for the primary power supply.l The efficiency of the primary power supply should be more than 85% and its power factor

must be more than 0.8.l The primary power supply is cooled in a natural manner. It can work continuously with

full load at a ambient temperature of 0°C to 40°C.l The output noise voltage (measured with a psophometer, plus the weighing factor) of the

primary power supply must meet the requirements listed in Table 21-8.l The primary power supply can automatically shut down the output at a low voltage.

500 kHz-30 MHz Single frequency: ≤ 1 mVeffective value

DC Power Distribution and Control PanelThe requirements for the DC distribution and control panel are as follows:

l The capacity of the primary power supply must be designed according to the powerconsumption of the transmission equipment of the terminal office. A certain margin mustbe reserved. Normally, use a high frequency switching power supply that has highconversion efficiency and that works in N+1 hot standby mode. An output current equalizermust be provided for each power module. The failure of a single power module does notaffect the normal operation of the entire DC power distribution system.

l Each control panel can access a minimum of two groups of storage batteries. When onegroup of storage battery fails, the other can supply power.

l Each control panel can access a minimum of five primary power supplies.l The power supply equipment must perform the automatic function to meet the non-

attendant requirement.l When the primary power supply charges the storage batteries in floating charge mode, the

number of primary power supplies in operation depends on the load. When one primarypower supply becomes faulty, it drops out automatically, and the standby primary powersupply automatically starts to operate.

l In the case of mains outage, the storage battery must discharge. When the mains resumes,it automatically recharges the discharged storage battery with a current 0.1 to 0.15 timesthe battery capacity. When the charge voltage reaches 56.4 V, it must automatically changeto the constant-voltage charge state.

l When the storage battery is fully charged, it automatically changes to the floating chargestate.

l When the power supply equipment fails or works abnormally, visual and audible alarmsare generated. The alarm information is transmitted to the operation and maintenancecenter.

l If a short circuit occurs in a tributary path of the power supply system, the entire powerdistribution system should not be affected by the sharp voltage reduction. The peak strikingvoltage should not cause any fault to the transmission equipment.

The OptiX optical transmission equipment also has strict restrictions on random transient noises,including the external magnetic interference and the interference from the equipment and thegrounding cables. The shorter the duration of the transient pulse is, the higher value the allowabletransient noises is. For the allowable values, see Figure 21-3.



152

Figure 21-3 Transient noise diagram

Requirements for the Basic DC Power Supply

The requirements for the basic DC power supply are as follows:

l Provide power supply in decentralized mode. That is, use multiple DC power supplysystems and set power supply devices on multiple sites.

l Use a DC power supply system that complies with the relevant standard. Set the outputvoltage value of the communication power supply to the range specified in the standard.

l Enhance the reliability of the AC power supply system and decrease the capacity of thestorage battery to a proper extent. When the reliability of the AC power supply system ata small communication station fails to be enhanced, increase the capacity of the storagebattery accordingly.

l Ensure that the total capacity of the high frequency switch rectifiers meet the requirementsof the communication payload power and the power of the storage battery charge. Configurethe rectifier modules in redundant mode. When less than 10 main rectifier modules areavailable, configure one standby rectifier module. When more than 10 main rectifiermodules are available, configure one standby module for each 10 rectifiers.

l Install two or more groups of storage batteries. The total capacity of one group of storagebattery depends on the time the power supply of the battery group can last. In mostcommunication offices, one group of storage battery must provide power supply for at leastone hour.

21.11 Lighting in the Equipment RoomThe equipment room of the OptiX optical transmission equipment is equipped with three lightingsystems:

l Active lighting system, which is powered by the mains supply.

l Backup lighting system, which is powered by the backup power supply (diesel electricgenerator) of the office.

l Emergency lighting system, which is powered by storage batteries when the mains supplyis interrupted but the backup power supply does not start to supply power.



153

21.12 Protection SystemThis topic describes the requirements for the protection system.

Antistatic ProtectionThe equipment-affecting electrostatic induction might derive from the two sources: externalelectric field such as outdoor high voltage transmission line or lightning; internal system suchas indoor environment, floor materials, and equipment structure.

Static electricity might damage the chips on integrated circuit boards and cause faults in softwareand electronic switch. Statistics shows that 60% of the damaged circuit boards are caused bystatic electricity. Therefore, it is important to take antistatic protection measures in the equipmentroom.

The following measures are recommended:l Ground the equipment well. Although the antistatic floor covered with semiconductive

materials is installed, copper foil must be used for grounding at certain points on the floor.The copper foil must be placed between the cement ground and the semiconductive floorand be connected with the grounding cable.

l Take dust-proof measures. Dust might cause severe harm to the optical synchronoustransmission equipment. Dust or other particles might cause poor connection betweenconnectors or metallic connecting points. In case of high humidity, dust can cause electricalleakage. In normal cases, equipment failures are caused by accumulated dusts, which isfound in maintenance. Electrostatic adherence is likely to occur, especially when thehumidity in the room is very low.

l Keep proper temperature and humidity. Too high humidity might make the metalcomponents rusty while too low humidity might induce static electricity.

l Wear an antistatic wrist strap and lab coat when touching a circuit board to preventelectrostatic damage to the equipment.

Interference PreventionAs the technologies and social economy develop, more and more electromagnetic signals aretransmitted in the air. These signals might affect the communication quality by causing cross-talk and stray noise, and even result in communication interruption. The electromagneticinterference (EMI) sources include the following:l Corona discharge of the electric transmission linel Transformerl Switchesl Waveform distortion of the power supply network caused during the operation of large

equipmentl Radio frequency (RF) interferencel Natural interference sources such as terrestrial magnetic field and external radiation.The interference, from either inside or outside the equipment or the application system, affectsthe equipment through conductive modes such as capacitance coupling, inductance coupling,electromagnetic wave radiation, common impedance (including grounding system), and cable(power and signal cables). In terms of external relations of the equipment, interference derives



154

from the signal cable, power cable, grounding system and spatial electromagnetic wave.Integrated circuits (ICs) have a certain interference resistance capability. Signal corruption andeven system malfunction, however, might occur when the external noises go beyond their anti-interference tolerance. It is impossible to eliminate or shield all the interference sources, but thefollowing measures can be taken to suppress the interference signals.l High frequency interference in the power supply network is generated when the primary

coil of the power supply transformer is coupled to the secondary coil through distributedcapacitors. To suppress such interference, use an appropriate transformer, and install a low-pass filter at the inlet of the power supply cable.

l The interference of the transient voltage in the power supply network can be reduced byinputting power directly from the primary transformer and adding a filter capacitor for theoptical synchronous transmission equipment.

l When the optical synchronous transmission equipment works in the 50 Hz mains powersupply network with the above interference, the surge voltage caused by the power supplynetwork and the over-voltage generated by lightening are passed to the power supply ofthe optical synchronous transmission equipment. This leads to computing errors of theprocessors. Therefore, before directly using the mains supply, take effective measuresagainst interference from power supply network.

l The key to eliminating the interference from the grounding system is to avoid loops amongvarious grounds, such as the signal ground (including analog and digital grounds), BGND,PGND and shield ground, or loops formed by large distributed capacitors. Otherwise, thecommon impedance interference from the grounding system might affect the operation ofthe equipment. In buildings other than high-rises, the working ground of the opticaltransmission equipment must be separated as far as possible from the ground for electricityequipment and lightning protection device.

l Prevent electromagnetic radiation interference from the surroundings to the equipment. Ifa high frequency transmitter exists in certain integrated communication buildings, itsinfluence on the optical transmission equipment must meet the relevant requirements.Independent power supplies are recommended for them.

l EMI from the telecommunications line must be restrained. Influenced by high frequencyelectromagnetic field (external interference), the core and sheath of the communicationcable bear high longitudinal voltage. Because of the asymmetry of cores in the cables, thelongitudinal voltage generates a horizontal noise voltage at the ends of the cores. Whenboth ends of the cable sheath are grounded, the sheath functions as a shielding layer, whichgreatly reduces the longitudinal voltage and reduces the interference voltage. Othereffective methods include: (1) reduce the voltage or current of the interference source; (2)minimize the line length and the spacing of the conducting wires to reduce the area of theaffected loop; (3) directly place the insulated conducting wires on the grounded floor; (4)use a dedicated grounding feedback cable to prevent co-impedance; (5) twist the signalcable and the feedback cable together to offset partial peripheral electromagneticinterference.

Fire ProtectionIn small equipment rooms, a certain number of portable fire extinguishers must be equipped foran initial fire control. In large equipment rooms, fixed fire extinguishing facilities must beequipped. An automatic fire alarm system must also be equipped in the equipment room. Alltelecom buildings with the fire alarm system must have fire emergency lighting system andevacuation instruction marks at important places, paths and gateways.

Anti-Earthquake RequirementsThe designed anti-earthquake intensity of the telecom equipment room must be one degree(Richter scale) higher than that for the common buildings. The equipment room building thatcannot meet the requirement must be reinforced. When installing the OptiX transmissionequipment, take the following anti-earthquake measures:

l Use a steel framework for the cabinet of the OptiX transmission equipment. Lockingdevices must be used to fix the boards in the cabinet.

l Ensure that the cabinet is reinforced with slide rail on the top and supports at the bottom.

Lightning ProtectionChimneys, antennae or other things that are over 15 m tall on the top of the equipment roombuilding must be designed according to the lightning protection requirements for civil buildings.Measures must be taken against direct flash and intrusion of lightning current. In the main high-rise transmission building, protective measures must be taken to prevent side lightning strokes,especially in frequent lightning areas. Therefore, designers must take appropriate measuresaccording to the actual situation. For example, connect the metallic external window frame tothe lightning protection wire; along the height of the building, place the metallic lightningprotection bands at a definite spacing on the outside wall. The main equipment-room buildingmust be provided with the following lightning protection measures:l Equip the building with lightning arrester nets or bands at the positions susceptible to

lightning strokes. Install lightning prevention wires or lightning rods on the top of chimneysand antennas that are protruding from the building. The cross-sectional area of thegrounding wire of the lightning protection device cannot be smaller than 2 mm2. Thespacing between the wires cannot be larger than 30 m.

l Ensure that the earth resistance of the earthing/grounding system is must be less than 10ohm.

l Ground the external cables and metallic pipes before they enter the building. The outdooroverhead cables must be equipped with lightening protection devices at the entrance of thebuilding.

l Use roof plates, beams and pillars made of reinforced concrete and the reinforcement baras the ground wires of lightening arresters.

In the past, lightning protection grounding of the building was separate from the grounding fortelecom system and power supply system, and a large distance was required between thegrounding objects. The distance requirement, however, is not met due to a small space of thebuilding. In fact, they cannot be separated in most cases, so joint grounding system isrecommended for the lightening protection grounding of the building The joint grounding systemshould connect the telecom BGND, PGND, lightning protection grounding of the building, andgrounding of the power frequency AC power supply system. A high earth resistance of the jointgrounding system is required. The earth resistance required by telecommunication is far lowerthan 10 ohms, and the grounding requirements for different telecom devices vary. Therefore,the resistance of the joint grounding system must be determined according to the minimumresistance required for the grounding device. Use steel bars in the walls and pillars of the buildingas ground wires for lightening protection. These wires must be electrically connected to equalizethe electric potential in the building.

23 Requirements of Cabling and Bundling

About This Chapter

This chapter describes the requirements of routing and bundling the cables.

23.1 Requirements of CablingThis topic describes the method and requirements of cable routing.

23.2 Requirements for Cable BundlingThis topic describes the method and requirements for binding the cables.

OptiX OSN 3500 Intelligent Optical Transmission SystemInstallation Guide 23 Requirements of Cabling and Bundling


162

23.1 Requirements of CablingThis topic describes the method and requirements of cable routing.

l For equipment room installed with supports and ESD protection floor, cables can bearranged in downward mode. That is, all cables can be routed through the interlayer of thefloor or the cable trough. If the upward cabling mode is adopted, cabling rack is requiredabove the cabinet for holding cables.

l The specifications and cross-sectional area of the cable, and the route and position forcabling should be designed beforehand.

l All cables should be arranged neatly, with their sheaths remaining intact.

l Communication cables, such as alarm cables, network cables and clock cables, should bearranged separately with the power cable and optical fibers.

l Turnings of the cable should be smooth, with the bend radius three times the cable diameteror above.

l Any damage to the insulation layer of the conducting line is not allowed.

l The cable arrangement should take the future maintenance and capacity expansion intoconsideration.

23.2 Requirements for Cable BundlingThis topic describes the method and requirements for binding the cables.

l The cables should be bound in a tidy, clear, and elegant manner. As a general rule, cablesare grouped by types, or grouped as needed when they are in a large number. Bind themwith cable ties and route them in either upward or downward cabling mode in the cablingarea at the two sides of the cabinet.

l Cables must be bundled when arranged in ducts. Bind the cables closely with appropriatetightness. The space between the cable ties should be even and the overall appearance ofthe cabling nice.

l You may not bind the cables when arranged in cable troughs. But they should be placedtidy and straight in the trough with no crossover. Moreover, the cables can not overflowthe trough. At two ends and turnings of the trough, use a plastic clip for the cables.

l Cables both inside and outside the cabinet must be bundled. Keep the cables bundled closelyand neatly.

l Use cable ties of different specifications for cables according to actual circumstances.

l Do not connect two cable ties in bundling. Otherwise, the binding strength will beweakened.

l After the bundling, cut the remaining part of the cable tie smoothly, removing all burrs.

l The space between the cable ties is even and is three or four times the size of the bundlediameter.

l When making turning for the bundled cable, keep the bend radius as big as possible to avoidbreaking the cable cores at the turning.

Figure 23-1 shows the specific operation of bundling.

frame number and the slot number. The dividing line is 1.5 mm x 0.6 mm in size with the colorof PONTONE 656c (light blue).

The cut dotted line helps to fold the label when affixing it to the cable, and its size is 1.0 mm x2.0 mm.

There is a mark "TO:" (upside down in the figure) at the lower right corner of the label. Themark is used to identify the opposite end of the cable on which the label is affixed.

Label for Power CablesThe label for power cables should be attached to the identification plate on the cable ties thatare bundled to the cable. The identification plate has an embossment of 0.2 mm x 0.6 mm around(symmetric on both sides), and the area in the middle is for affixing the label, as shown in Figure24-2.

24.2 Information Carried on LabelsThis topic provides the information about on the labels of the signal cables and power cables.

24.2.1 Labels for Power CablesLabels for power cables are only affixed on one side of the identification plates. On the labels,there is information (the part after the mark "TO:") about the location of the device on the otherend of the cable, like the location of control cabinet, distribution box or power socket.

24.2.2 Labels for Signal CablesThe two sides of the label affixed on the signal cable carry information about the location of theports connected to both ends of the cable.



167

The information is given like this:

l Area 1 contains the location information of local end of the cable.l Area 2 (with the mark "TO:") contains the location information of the opposite end of the

cable.l Area 3 has been folded up inside the label.

Printed parts on the label for signal cables, as shown in Figure 24-3.

Figure 24-3 Label for signal cables

Area 3Area 1

Area 2 TO:

Seen from the cabling end of the equipment, the text part of the label is on the right side of thecable. The side with "TO:" that is facing outside carries the location information of the oppositeend, and the other side carries the location information of the local end. Therefore, theinformation in Area 1 at one end is the same as the information in Area 2 at the other end of thecable, and vice versa. In other words, the local information at one end is called the oppositeinformation at the other end.

24.2.3 RemarksTo use labels, focus on the following points.

l When printing/writing and affixing labels, pay attention to keep the labels clean.l Since the label paper is made of moistureproof and waterproof material, ink-jet printers

and ink pens are forbidden for printing and writing labels.l Labels should be affixed with good order in alignment.l Cable ties should be bundled in the same position of power cables, with identification plates

on the same side.l The positions of "up", "down", "right" or "left" are all based on the viewpoint of the

engineering person who is working on the label.

24.3 Filling Information on LabelsThis topic describes how to fill information on labels. The contents can be printed or written onthe labels. Printing is recommended for the sake of high efficiency and eye-pleasant layout.

24.5 Frequently Used Engineering LabelsThis section describes the frequently used engineering labels. The other labels are omitted here.You can perform the operation as required on site.

24.5.1 Engineering Labels for Power CablesThe labels are affixed to the DC cables that provide power for the cabinets, and the protectiongrounding cables, including the -48 V, PGND, and BGND cables. The labels for DC powercables are affixed to one side of the identification plates on cable ties.

Table 24-2 shows the information carried on the labels for the DC power cables.

Table 24-2 Information on labels affixed to the DC power cables

Content Meaning

MN(BC) - -1 MN (BC): BC is written right under MN. On the loaded cabinetside, MN identifies the row and column number of the powerdistribution equipment like the control cabinet and distributionbox, BC identifies the row and column number of the -48 Vconnector (if there is no row number or column number, or theconnector can be identified without them, BC can be omitted).BGND and PGND have no row and column number foridentification. On the power cabinet side, only MN is used toidentify the cabinet.

MN(BC) - -2

MN(BC) - BGND

MN(BC) - PGND

The label only carries location information about the opposite equipment, the control cabinet orthe distribution box, while information of the local end is not necessary. Table 24-2 lists theinformation of two -48 V power supplies on the label. The information for other DC voltages(such as 24 V, 60 V) should be given in similar methods. Make sure that labels are affixed incorrect direction. That is, after the cable ties are bundled onto the cable, the identification plateswith the labels should face up, and the text on the labels in the same cabinet should be in thesame direction, as shown in Figure 24-10.

the loaded cabinet side.



174

On the loaded cabinet side, the label marked with "A01/B08--2" on the cable indicates that thecable is -2 DC supply, which is from the eighth connector on the second row of -48V bus bar inthe cabinet on Row A, and Column 1 in the equipment room.

On the distribution unit side, the label marked with "B03--2" indicates that the cable is -2 DCsupply, which is from the loaded cabinet on Row B, Column 03 in the equipment room.

NOTE

l In the power distribution unit (or the first power cabinet of a row in the transmission equipment room),every terminal block on the - connector bar has a numeric identification. For example, in the abovelabel of "A01/B08--48V2", "08" (or sometimes "8") is the numeric identification of the terminal block.

l PGND and BGND are two copper bars, on which the terminal blocks are connected, therefore whichterminal is connected makes no difference. It is only necessary to give the row and column of the powerdistribution unit, instead of giving the specific serial number of the terminal block on the copper bar.For example, if the label on the loaded cabinet side is "A01-BGND", it means that the power cable isa BGND that connects BGND copper bar in the power distribution unit on Row A, Column 01 in theequipment room. Information on the labels for PGND cables should be given in the similar way.

24.5.2 Engineering Labels for External Cables of Alarm BoxThe external cables of alarm box are connected with the first subscriber cabinet of each row(used for power distribution). Labels posted on the first cabinet of each row should indicatewhich equipment is using the access terminal.

Labels are not needed on the equipment side unless there is special requirement. In this case,only Area 2 of the label should be filled in.

Table 24-3 shows the information on the labels of alarm box external cables.

Table 24-3 Information on labels affixed to the external cables of alarm box

Content Meaning Example

MN MN: serialnumber of thecabinet in theequipment room
