1.6.1 Usage of FibersThe laser beam can cause damage to your eyes. Handle optical fibers with care.

DANGERDo not look at the optical port or connector when installing and maintaining the optical interfaceboards or optical fibers. The laser beams may cause permanent eye damage.

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.

Cleaning Fiber Connectors and Optical InterfacesUse special cleaning tools and materials to clean the fiber connectors and optical fiber interfacesof the optical interface board. The common cleaning tools and materials are as follows:l Special cleaning solvent: It is preferred to use isoamylol. Propyl alcohol, however, can also

be used. It is not recommended 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, using with the recommended cleaning solventl Special magnifier for optical connectors

Replacing FibersWhen you replace a fiber, cover the fiber connector of the fiber that is not in use by using theprotective cap.



1-9

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

damages the optical interface.l Do not connect an optical attenuator to the level optical interface. Use the optical

distribution frame (ODF) to connect an optical 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 radiation

is 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.



Commissioning Guide


Issue 03 (2011-02-28)

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.

1.7 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: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

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 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

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 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.



1-15

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.

2 Selection of Commissioning MethodsIn different scenarios on the existing network, you need to select different commissioningmethods to commission the OptiX 155/622H.Based on the conditions of the telecommunication room, user requirements, engineeringmanagement, and personnel skills, there are two methods for commissioning the OptiX155/622H: onsite commissioning and remote commissioning.

Onsite CommissioningThe onsite commissioning refers to a commissioning method wherein the softwarecommissioning engineers and the hardware installation engineers are physically present on thesite of the case-shaped equipment, and perform the hardware installation and softwarecommissioning of the case-shaped equipment.

Remote CommissioningThe remote commissioning refers to a commissioning method wherein the hardware installationengineers must be physically present on the site to perform the hardware installation and toensure that the optical fibers are connected normally whereas the software commissioningengineers at the NMC remotely log in to the new NE and perform the subsequent softwarecommissioning.

Principles for Selecting Commissioning MethodsOn principle, the remote commissioning method is recommended. Huawei engineers, however,can determine the commissioning method based on the actual situations of the site. For example,the onsite commissioning method is recommended in the following cases:l The OptiX 155/622H is interconnected with the third-party equipment, and the ECC

information between the gateway NE and the OptiX 155/622H cannot be obtained.l The conditions in the telecommunication room are not met (for example, the optical cables

or the power supply is not available on the site), and the project is tightly scheduled.l The parameters of the optical interfaces and electrical interfaces of the equipment need to

be measured on site.

If fibers are connectedin an incorrect manner, errors may occur during the later stages of commissioning, andconsequently the running services may be affected. To prevent impact on the latercommissioning and service configuration, check the fiber connection according to the networktopology to ensure that the fibers are connected correctly.5.13 Checking the Connection of an NM Computer to the EquipmentThe NM software runs on the NM computer to manage the equipment. If the computer isconnected in an incorrect manner, the NM cannot manage the NEs. To prevent the incorrectconnection of the NM computer, check the connection between the NM computer and theequipment and ensure that the connection is normal.5.14 Searching for the NEsAfter checking the connections of the NMS computer and the equipment, the softwarecommissioning engineers need to search for the NEs in the data center to commission theequipment.5.15 Searching for the Fibers and CablesAfter the NEs are found, the software commissioning engineers need to search for the fibers andcables in the data center to commission the equipment.5.16 Changing the NE IDAfter you log in to the NE through the U2000, you need to change the NE ID according to theplan of the NE IDs. In this manner, you can ensure that the actual NE IDs are consistent withthe planned NE IDs.5.17 Setting the NE IPAfter logging in to the NE by using the U2000, you need to change the NE IP according to theIP planning of the actual NEs. The IPs of the actual NEs must comply with the IP planning.5.18 Setting the NE Name, Date, and TimeYou can use the U2000 to set the NE name, date, and time to ensure that the recorded and reportedalarms and performance events on the U2000 are correct.5.19 Configuring Clock, Services, and ProtectionUse the U2000 to configure clock, services, and protection based on the engineering files toprepare for the subsequent commissioning.5.20 Creating and Configuring the NetworkAfter checking the fiber connection and the connection of the NM computer, use the U2000 tocreate and configure the network as specified in the engineering documents. Creating andconfiguring the network is also the preparation for the system commissioning.
