When the temperature of the battery is higher than 60C, you need to check whether theelectrolyte overflows. If the electrolyte overflows, take appropriate measures immediately.



8

Battery Leakage

NOTICEIn the event of acid overflow or spillage, neutralize the acid and clean it up appropriately.

When handling a leaky battery, protect against the possible damage caused by the acid. Whenyou find the electrolyte leaks, you can use the following substances to counteract and absorb theleaking electrolyte:l Sodium bicarbonate (NaHCO3)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

NOTICEIf 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.



9

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 also

be 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 connectorsFor cleaning steps, see Task Collection "Cleaning Fiber Connectors and Adapters" in the OptiXRTN 950 Radio Transmission System Maintenance and 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.Figure 1-2 shows a slanting optical interface, and Figure 1-3 shows a level optical interface.

1.6.2 Electromagnetic ExposureThis topic describes safety precautions for electromagnetic exposure.If multiple transmit antennas are installed on a tower or backstay, keep away from the transmitdirections of the antennas when you install or maintain an antenna locally.

NOTICEEnsure that all personnel are beyond the transmit direction of a working antenna.

1.6.3 Forbidden AreasThe topic describes requirements for a forbidden area.l Before entering an area where the electromagnetic radiation is beyond the specified range,

the associated personnel must shut down the electromagnetic radiator or stay at least 10meters away from the electromagnetic radiator, if in the transmit direction.

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

1.6.4 LaserThis topic describes safety precautions for lasers.



11

CAUTIONWhen 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 therefore it hasvery high power density and is invisible to human eyes. When a beam of light enters eyes, theeyes may 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.

Safety Instructions Regarding LasersTo avoid laser radiation, obey the following instructions:l All operations should be performed by authorized personnel who have completed the

required 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.

CAUTIONStrong radio frequency can harm the human body.



12

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.

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

The requirements for working at heights are as follows: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.

CAUTIONWhen 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.

1.7.2 Using LaddersThis topic describes safety precautions for using ladders.

Checking Laddersl Before using a ladder, check whether the ladder is damaged. After checking that the ladder

is in good condition, you can use the ladder.l Before using a ladder, you should know the maximum weight capacity of the ladder. Avoid

overweighing the ladder.

Placing LaddersThe proper slant angle of the ladder is 75 degrees. You can measure the slant angle of the ladderwith an angle square or your arms, as shown in Figure 1-5. When using a ladder, to prevent theladder from sliding, ensure that the wider feet of the ladder are downward, or take protectionmeasures for the ladder feet. Ensure that the ladder is placed securely.



14

Figure 1-5 Slanting a ladder

Climbing Up a LadderWhen climbing up a ladder, pay attention to the following points:l Ensure that the center of gravity of your body does not deviate from the edges of the two

long sides.l Before operations, ensure that your body is stable to reduce risks.l Do not climb higher than the fourth rung of the ladder (counted from up to down).If you want to climb up a roof, ensure that the ladder top is at least one meter higher than theroof, as shown in Figure 1-6.

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

Drilling Holes

CAUTIONDo 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 by

the 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

CAUTIONWear 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 operating

fans before the fans are powered off and stop running. Otherwise, the hands or the boardsare damaged.

Carrying Heavy ObjectsWear protection gloves when carrying heavy objects. This is to prevent hands from being hurt.



16

CAUTIONl 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

NOTICEWhen 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

NOTICEBind 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 0C.l If the cables are stored in a place where the ambient temperature is below 0C, transfer

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

l Handle the cables gently, especially in a low-temperature environment. Do not performany improper operations, for example, pushing the cables down directly from a truck.

High Temperature

CAUTIONIf the ambient temperature exceeds 55C, the temperature of the front panel surface marked the

flag may exceed 70C. When touching the front panel of the board in such an environment,you must wear the protection gloves.

IF Cables

CAUTIONBefore installing or removing an IF cable, you must turn off the power switch of the IF board.

3.2 Preparing the Certificate File for NE Access from a USBFlash Drive

This section describes how to prepare an RTN.CER file used for certification of NE access froma USB flash drive. The file allows you to perform site commissioning, database backup/restoration, and software upgrades using a USB flash drive.

PrerequisitesThe NMS is available.

Tools, Equipment, and MaterialsU2000

NOTE

Web LCT also supports this operation and the steps are the similar to those on the U2000.

ProcedureStep 1 Optional: Query the encryption algorithm used for the NE password and set related parameters

accordingly.



29

NOTEThe supported encryption types are MD5, SHA256, and PBKDF2. The default encryption type is PBKDF2.

Step 2 Access the directory for saving the USB file generation tool.NOTE

l On the U2000, the tool is stored under D:\oss\client\client\tools\usbtool (an example).l On the Web LCT, the tool is stored under D:\WebLCT\weblct\tools\usbtool (an example).

Step 3 Run startup_usbTool.bat.

The USB File Generation Tool dialog box is displayed.Step 4 Generate a certification file for NE access from a USB flash drive.

1. Enter the user name and password for logging in to the NE to be commissioned.NOTE

l Default user name: szhwl Default password: nesoft

2. Select an encryption type according to the encryption algorithm used by the NE.NOTE

l The supported encryption types are MD5, SHA256, and PBKDF2. The default encryption type isPBKDF2.

l If you do not know the encryption algorithm used by the NE, select All. In this case, the certificationfile generated by the USB file generation tool includes three segments of ciphertexts for the password.Each segment corresponds to one algorithm from MD5, SHA256, and PBKDF2. The NE decrypts theciphertexts according to the used encryption algorithm.

l If PBKDF2 or All is selected, set SSL Certificate and Certificate File Path. SSL Certificate includestwo types: Default and Custom.l If you want to use the default certificate file of the U2000, select Default. The default certificate

file server.p12 is saved in the U2000 server path (such as D:\oss\server\etc\ssl\nemanager\default\keyStore\PFX\), and the default key is Changeme_123, so this file can be used only when theUSB file generation tool is run on the U2000 server. If you want to use another certificate file,select Custom.

l Customized certificates include two types: *.crt and *.p12. A *.p12 certificate is encrypted, so akey is required.

l Both *.crt and *.p12 certificates need to be synchronized with the NE. For details, see the U2000Administrator Guide.

3. Click Generate File.



30

Step 5 Click OK in the displayed confirmation dialog box.

Step 6 Go to the directory where the RTN.CER file is stored, and copy it to the root directory of theUSB flash drive.

NOTE

l On the U2000, the RTN.CER file is stored under D:\oss\client\client\tools\usbtool\output (an example).l On the Web LCT, the RTN.CER file is stored under D:\WebLCT\weblct\tools\usbtool\output (an

example).l Save the RTN.CER file before closing the USB file generation tool. Otherwise, the file will be automatically

deleted when you close the tool.

Step 7 Click Close.----End

3.3 Obtaining a USB Flash DriveObtain a proper USB flash drive before you commission a site by using a USB flash drive.

Supported ModelThe recommended USB flash drive for the OptiX RTN 950 is Netac U208 with a 4 GB capacity.A USB flash drive of another model or capacity may cause incompatibility issues. If a USB flashdrive of another model or capacity is required, contact the local Huawei office for confirmation.

3.4 Determining the Commissioning MethodBy using the U2000 for commissioning, engineers can adopt the single-hop commissioningmethod or network commissioning method based on the network size.

ContextNOTE

In the following instructions for both types of commissioning methods, site commissioning and systemcommissioning are defined as follows:l Site commissioning refers to commissioning that is performed on a hop and sites at both ends of the

radio link by connecting the commissioning tool to the NE at a single site.l System commissioning refers to commissioning that is performed on all the NEs in the network by

connecting the commissioning tool to a gateway NE where it configures the commissioning data foreach site.

Single-hop CommissioningThe single-hop commissioning method is preferred for small-scale microwave transmissionnetworks (for example, a network with only one or two radio link hops). By performing single-hop commissioning, you can complete all site and system commissioning items at a time. Themajor commissioning steps are as follows:1. On both ends of a radio link, power on the NEs.2. Use the Web LCT to configure site commissioning data or copying site commissioning

data from the USB flash drive.NOTE

The commissioning data is all NE data including service data and clock data.3. Use the Web LCT to complete the site commissioning items.



32

4. Use the Web LCT to complete the system commissioning items.NOTE

The Web LCT is used for single-hop commissioning, and therefore this document does not detail how to usethe Web LCT. For details about how to use the Web LCT, see the Commissioning Guide in the documentationpackage of the Web LCT version.

Network CommissioningThe network commissioning method is usually used for large-scale microwave transmissionnetworks. The major commissioning steps are as follows:1. On both ends of a radio link, power on the NEs.2. Use the Web LCT to configure site commissioning data, or copying site commissioning

data from the USB flash drive.NOTE

The commissioning data may contain only data that is required for DCN and link availability.3. Use the Web LCT to complete the site commissioning items.4. Use the U2000 to complete the system commissioning items at sites where services

converge.

3.5 Checking Commissioning ConditionsEnsure that the equipment meets the commissioning requirements for the site or system prior toperforming such tasks. The following sections provide a non-exhaustive checklist for bothscenarios.

3.5.1 Site CommissioningEnsure that the equipment and weather meet the requirements for site commissioning.

ContextDetails about these requirements are as follows:l Hardware installation has been completed and has passed the installation check.l Power is available to the equipment.l The service signal cables that are connected to other equipment have been properly routed.l The appropriate risk control measures to arrest falling objects and ensure personnel safety

are in place.l There is no adverse weather (such as wind, rain, snow, or fog) that could hinder or impact

the commissioning.

3.5.2 System CommissioningEnsure that the equipment and weather meet the requirements for system commissioning.



33

ContextDetails about these requirements are as follows:l Site commissioning at both ends of a radio link has been completed.l DCN communication on the radio network is normal.l There is no adverse weather (such as wind, rain, snow, or fog) that could hinder or impact

the commissioning.

5.1 Powering On the EquipmentBy checking the power-on process of equipment, you can verify whether the hardware systemof the equipment and the power system are functioning properly.

Prerequisitesl Hardware installation has been completed and has passed the installation check.l The power system is available. The voltage, pole connection, and fuse current of the power

system have been checked in the process of connecting power cables.l The power supply (for example, the power distribution box of the cabinet) has been turned

off.

Tools, Equipment, and MaterialsNone.

Contextl For the OptiX RTN 950, the recommended fuse currents are listed in Table 5-1.

Table 5-1 Fuse currentsChassis Recommended Fuse CapacityOptiX RTN 950 20 A

NOTEThe recommended fuse capacity of 20 A can meet requirements under the maximum powerconsumption. Customers can compute the fuse capacity according to the actual power consumption.The fuse capacity should be larger than or equal to (total power consumption x 1.5)/(rated voltage x87.5%). For example, when the rated power supply is -48 V and the total power consumption of theIDU is less than or equal to 420 W, the fuse capacity can be set to 15 A (= [420 x 1.5]/[48 x 87.5%]).

l The OptiX RTN 950 supports the following system control, switching, and timing board:Chassis Board TypeOptiX RTN 950 CSH/CST



43

Precautions

NOTICEl If the equipment is configured with two PIU boards, the nominal voltage for the input power

of each PIU board must be the same.l The ODU-PWR switch on the front panel of the IF board is designed with a locking device.

Hence, you must pull out the switches lightly before you turn it. If the switch points to "O",the switch is turned off. If the switch points to "I", the switch is turned on.

l If the output voltage of the power supply does not meet test requirements, do not power onthe cabinet. First, reconstruct the power supply and then test the output voltage again.

ProcedureStep 1 Verify that the power cables of the chassis are correctly connected. Then, power on the equipment

and check the status of the indicators. In normal conditions, the PIU/FAN indicators are steadygreen, as shown in Figure 5-1. Table 5-2 provides the descriptions for the different states of theindicators.

Table 5-2 Status of indicatorsIndicator State DescriptionPWR Steady green Indicates that the power supply is in

the normal state.Off Indicates a power failure.

FAN Steady green Indicates that the fan is runningproperly.

Steady red Indicates that the fan is faulty.Off Indicates that the fan is powered off.
