5.1 On-site Cable Assembly and Installation5.1.1 Cable Assembly PrecautionsChecking the Appearance of CableslIf the cable jacket or insulation is visibly dirty, clean it before assembly.lIf the jacket or insulation of a cable has visible damage, irreparable scuffing, or otherdefects, do not use the cable.lIf the shield layer of a cable is damaged, do not use the cable.lIf the cable jacket or insulation cracks after the cable is bent or twisted, discard this cableand check whether other cables have the same problem. If other cables have the sameproblem, replace these cables.Checking the Appearance of ConnectorslDo not use connectors with visible defects, damage, rust or scuffing.lDo not use connectors if their shells or pins have exposed part or uneven plating, or theirpins are lost, broken, or bent.lDo not use connectors that have dirt on their pins or in their jacks or if there areconductors between pins or between pins and the shell.Precautions for AssemblylUse dedicated tools or tools delivered by Huawei and follow the methods given hereduring assembly.lHold terminals of cables instead of pulling the cables themselves when installing orremoving cable components.lTake the following precautions when cutting or stripping cables:–Make cables slightly longer than necessary.–Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the coils usingbundling ropes. The inner diameters of the coils should be larger than 20 times theouter diameters of the cables.–When stripping the jackets of cables, avoid damaging the shield layers (braid oraluminum foil), insulation, core conductors, and other jackets that do not need to bestripped.–After assembling cables, cut all visible cross sections of jackets to ensure that thecross sections are arranged neatly.–Do not touch the core conductors of cables with your hands. Terminate exposedconductors in a timely way after stripping off insulation so that the surface of theconductors does not become oxidized.lTake the following precautions when crimping and connecting cables or connectors:–The terminals and conductors should be connected tightly after they are crimped.They should not be moved or turned.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.26

For example, in this document, the adapters of cable connectors have separate interfaces. In theactual situation, the adapters may have interfaces fixed on equipment.Use dedicated tools provided or specified by Huawei and follow the installation proceduredescribed here.Bending RadiusUnless otherwise specified, bending radius (R) of cables or fibers must meet the requirementslisted in Table 5-9.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.49
Table 5-9 Bending radius of cables or fibersCable or Fiber Bending Radius (R)Ordinary cable In normal cases, R ≥ 2d. When the cable isconnected with a connector, R ≥ 5d.Fiber R ≥ 40 mm (1.57 in.); Bending angle > 90° NOTEThe letter d indicates the diameter of a cable or fiber.Precautions for InstallationlHold terminals of cables instead of pulling the cables themselves when installing orremoving cable components.lDo not insert a connector forcibly when the connector is blocked. Use a dedicated tool topull out the connector. Install the connector again after you check that the pins areinserted properly.lBefore tightening screws on cable connectors, ensure that the connectors are properlyconnected to their adapters. Tighten the screw with appropriate force using a flat-head orPhillips screwdriver instead of bare hands or an electric screwdriver. If the screw cannotbe screwed into the tapped hole, determine the reason and try again. Do not apply toomuch force, or the screw or adapter may be damaged.lWhen removing densely aligned cables or fiber connectors, use dedicated pliers such ascable-pulling pliers and fiber-pulling pliers.lDo not twist, bend, stretch, or extrude fibers during installation.lCover the idle fiber connectors with dust caps. Remove the dust caps before using thefiber connectors.Requirements for Cable RoutinglTo protect cables, remove the burrs in the cable through-holes or install protective ringsin the holes.lTo ease the connection and to avoid stress, keep cable joints slack. After connectingmultiple cables to a connector that has multiple interfaces, keep the cables slack to avoidgenerating stress.lBind or clean cables gently because cable distortion affects signal quality.lKeep cables away from moveable components such as doors.lSharp objects must not touch cable wiring to prevent damage to cables.lTo protect power cables, route power cables of the active and standby power modulesseparately.Installing Power AdaptersInstalling the OT TerminalAP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.50

Type and StructureLabel for Signal CablesThe label for signal cables is L-shaped with fixed dimensions, as shown in Figure 5-81.Figure 5-81 Label for signal cables To specify more clearly the position of a cable, use the dividing lines on the label. Forexample, there is a dividing line between the cabinet number and the chassis number, andanother one between the chassis number and the slot number. Each dividing line is light blue(Pantone 656c) and 1.5 mm x 0.6 mm (0.06 in. x 0.02 in.).The cut dotted line helps to fold the label when affixed to the cable, and its size is 1 mm x 2mm (0.04 in. x 0.08 in.).The word "TO:" (upside down in the figure) at the lower right corner of the label is used toidentify the opposite end of the cable on which the label is affixed.Power Cable LabelThe label for power cables should be attached to the identification plate on the cable ties thatare attached to the cable. The identification plate has an embossed area 0.2 mm x 0.6 mm(0.008 in. x 0.02 in.) around (symmetric on both sides), and the area in the middle is foraffixing the label, as shown in Figure 5-82.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.83

Printing is recommended for the sake ofhigh efficiency and eye-pleasant layout.Template for PrintingYou can obtain a template from the Huawei local office to print labels.The template is made in Microsoft Word. Follow these instructions to use the template:lYou can modify the contents of the template. Do not change settings of centeredcharacters, direction, and fonts.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.84
lIf many characters need to be filled in, decrease the font size, but make sure that theprintouts are clear and legible.Merging Cells in the TemplateTo merge two or more cells, do as follows:1. Select Edit/Select All.2. Select Format/Borders and Shading/Borders. Select Box tab and click OK.3. Drag the mouse to select cells to be merged and select the Table/Merge Cells.Requirements on the PrinterTo print labels, use a laser jet printer of any model. Before printing labels, set up the page andtry printing.1. Try printing on ordinary paper with both sides blank. Place the blank paper over thewhole page of the label paper, and check whether the page setup conforms to the labellayout.2. Make sure the printer properties, such as "paper size" and "direction", have been setcorrectly.–If the printout conforms to the sheet of labels, print the labels on the label paper.–If the printout does not conform, adjust the page setup and try printing again untilthe correct printout is produced.The method for adjusting the page setup is as follows.1. Select File/Page Setup.2. Select Layout and set Header and Footer as 0.3. Select the Margins tab page. Select Left for Gutter Position and adjust the values of Top,Bottom, Left, and Right.NOTEIf the warning prompt as shown in Figure 5-83 appears before printing, click Ignore to continuethe printing.Figure 5-83 Warning prompt before printing After the page setup has been made correctly, save it for future use. This page setup is onlynecessary the first time you use the template to print the labels.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.85
Requirements for Feeding the PrinterThe label paper consists of two layers and has undergone multiple processing procedures suchas printing and cutting. No matter what model of printer you use, feed in the labels one pageat a time. To avoid jamming the labels, never use the auto-feed mode.Feed in the label paper in the correct direction to ensure that the text is printed in a correctposition.Requirements for the Printed LabelMake sure that the printed labels satisfy the following requirements:lAll the printouts must be on the label, and nothing should be printed on the backing layerof the label page.lContents in the cells should be aligned in the center. In a single-line printout, thedividing lines and the word "TO:" should not be covered by printed characters.lWhen the cells are merged and the printouts are made in multiple lines, avoid coveringthe word "TO:" when printing the text. Use the space bar to move the text to the nextline.Writing LabelsWriting ToolsTo make sure the printouts are clear and legible, use black markers instead of ball-point pensto write the labels.If no marker is available, black ball-point pens are allowed, although not recommended.Compared with ball-point pens, water-proof markers are better. When writing with a ball-point pen, do not leave the oil on the label, which may contaminate the label and blur thewords.NOTEThe delivered marker has two nibs. Use the smaller nib to write the labels.FontFor the sake of legibility, use standard block letters and numbers as shown in Table 5-21(Times New Roman).Table 5-21 Standard typeface for handwriting0123456789 A B C D E F G HI J K L M N O P QR S T U V W X Y Z Determine the size of characters based on the number of letters or digits and ensure that thecharacters are distinct and tidy.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.86

Engineering Labels for DC Power CablesThese labels are affixed to the DC power cables that provide power supply for cabinets,including the -48 V, PGND, and BGND cables. Here, the DC power cables also include powercables and PGND cables.The labels for DC power cables are affixed to one side of the identification plates on cableties. For details of the labels, see Table 5-26.Table 5-26 Contents of the labelContent MeaningMN(BC)-B--48VnMN(BC): BC is written right under MN.B: chassis number, numbered in bottom-up order with two digits, forexample, 01.N: power socket number, numbered as 1 to 3 in the bottom-up and left-to-right orders.On the loaded cabinet side, only MN is used to identify the cabinet.On the power cabinet side, MN identifies the row and column numberof the power distribution equipment like a control cabinet anddistribution box, and BC identifies the row and column number of the-48 V connector. If there is no row number or column number, or theconnector can be identified without them, BC can be omitted. It isunnecessary to identify the row and column number for BGND andPGND.MN(BC)-B-BGNDMN(BC)-B-PGND The label only carries location information about the destination direction of the power cablewhereas information about the local end is unnecessary. That is, the label only carries locationinformation about the opposite equipment, the control cabinet, or the distribution box. Table5-26 lists the information on two -48 V power supplies on the label. The information on otherDC voltages, such as 24 V and 60 V should be given in similar methods.Make sure that labels are affixed in the correct direction. That is, after the cable ties arebundled onto the cable, the identification plates with the labels should face up, and the text onthe labels in the same cabinet should be in the same direction. For details, see Figure 5-93.Figure 5-93 Example of the labels for DC power cables AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.96
The meaning of the label in Figure 5-93 is as follows:lOn the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates that thecable is -48 V DC supply, which is from the eighth connector in row B of -48 V bus barin the cabinet in row A, and column 1 in the equipment room.lOn the distribution box side, the label "B03--48V2" indicates that the cable is -48 V DCsupply, connected to DC power socket 2 in row B, column 03 in the equipment room.NOTEIn the power distribution box or the first power cabinet of a row in a transmission equipment room,every terminal block on the -48 V 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.PGND and BGND are two copper bars, on which the terminal blocks are short-circuited.Therefore, it makes no difference which terminal is connected to them. It is only necessary togive the row and column of the power distribution box, instead of giving the specific serialnumber of the terminal block on the copper bar. For example, if the label on the loadedcabinet side is "A01-BGND", it means that the power cable is a BGND that connects BGNDcopper bar in the power distribution box in row A, column 01 in the machine room.Information on the labels for PGND cables should be given in a similar way.Engineering Labels for AC Power CablesThese labels are affixed to both ends of an AC power cable that provides AC power supply tocabinets, including 110/220 V, PGND, and BGND cables. The 110/220 V AC cables andrelated PGND and BGND cables are covered with an insulating sheath, so the labels need tocontain only the word "AC" and the cabinet numbers.The labels for AC power cables are affixed to one side of the identification plates on cableties. For details, see Table 5-27.Table 5-27 Label contentContent MeaningMN-(B)-ACn MN: serial number of the cabinet or the socket where the power is ledinB: chassis number, numbered in bottom-up order with two digits, forexample, 01.n: power port number, numbered as 1 to 3 in bottom-up and left-to-rightorder.Serial number of the socket where the power is led in: the location ofthe socket is marked according to the actual situation. If the sockets canbe identified by row numbers and column numbers, they can benumbered following the same rule for the cabinets. If the socketscannot be identified by rows and columns, specify the detailedlocations to avoid confusion with other sockets. The label only carries location information about the opposite equipment and the powersocket; information about the local end is unnecessary.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.97
Make sure that labels are affixed in the correct direction. That is, after the cable ties arebundled onto the cable, the identification plates with the labels should face up, and the text onthe labels in the same cabinet should be in the same direction, as shown in Figure 5-94.Figure 5-94 Labels for AC power cablesLabel on the loaded cabinet side(indicating the position of the cableon the power distribution box)Label on the distribution box side(indicating the position of the cableon the loaded cabinet side) Meaning of the label in Figure 5-94.lOn the equipment cabinet side, the label marked "A01-AC1" indicates that the powercable is connected to the first AC power socket of row A and column 01 in theequipment room.lOn the power socket side, the label marked "B01-AC1" indicates that the power cable isconnected to the first AC power socket in the cabinet of row B and column 01 in theequipment room.5.5 Guide to Using Optical ModulesCommon Faults of an Optical ModuleNOTEThe system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrectinformation. You are advised to use Huawei-certified optical modules. Obtain the electronic label of theoptical module and contact technical support personnel to confirm whether it is a Huawei-certified opticalmodule.1. An optical module is not completely installed in position.If the optical module is not completely installed in position and the latch boss is notsecured, the device cannot identify the optical module. After the optical module worksfor a long time, it will be ejected under external stress.2. The optical receptacle on an optical module is contaminated.If an optical module is not cleaned or protected properly, contaminants may accumulateon the fiber pin in the optical module. As a result, the coupling efficiency is reduced,optical signals are cut off, or even worse, the surface of the fiber pin is damagedpermanently.3. An optical module is burnt.If high-power optical signals (caused by an optical time domain reflectometer or self-loop test) are transmitted through an optical module that is used for long-distancetransmission but no optical attenuator is used, the optical power will exceed the overloadpower of the avalanche photodiode (APD). Then the optical module is burnt.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.98
The preceding faults lead to temporary or long-term cut-off of optical signals; or even causepermanent damages to the optical module, affecting communication services.Measures to Prevent a Loosened Optical Module1. When installing an optical module, insert it in position. If you hear a click or feel a slightshake, it indicates that the latch boss is secured.If the latch boss is not secured, the gold finger of the optical module is not in goodcontact with the connector on the board. In this case, the link may be connected butoptical signals will be cut off or the optical module will be loosened when the opticalmodule is shaken or hit.2. Figure 5-95 shows the release handle on an optical module when it is open and closed.When inserting the optical module, make sure that the release handle is closed. At thistime, the latch boss locks the optical module. After the optical module is inserted, trypulling it out to see if it is installed in position. If the optical module cannot be pulledout, it is secured.Figure 5-95 State of the release handle Close the release handle Open the release handleMeasures to Prevent Receptacle Contamination1. Cleaning tissues must be prepared on site. You need to clean the optical connector beforeinserting it in the receptacle. This protects the receptacle against contamination on thesurface of the optical connector.Figure 5-96 Cleaning optical fibers with special cleaning tissuesAP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.99
NOTEPlace at least three cleaning tissues on the work bench. As shown in Figure 5-96, wipe the end ofan optical connector from left to right or from right to left on a cleaning tissue, and then move theconnector end to the unused part of the cleaning tissue to continue.2. Cover an unused optical module with a protective cap to prevent dust, as shown inFigure 5-97.Figure 5-97 Installing a protective cap If no protective cap is available, use fibers to protect the optical module, as shown inFigure 5-98.Figure 5-98 Using fibers to protect an optical module 3. Cover unused optical connectors with protective caps, as shown in Figure 5-99, and thenlay out fibers on the fiber rack or coil them in a fiber management tray to prevent fibersfrom being squeezed.Figure 5-99 Installing a protective cap on a fiber 4. If a receptacle or an optical connector has not been used for a long time and is notcovered with a protective cap, you need to clean it before using it. Clean a receptaclewith a cotton swab, as shown in Figure 5-100. Clean an optical connector with cleaningtissues.AP2030DNHardware Installation and Maintenance Guide 5 AppendixIssue 05 (2016-07-22) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.100
Figure 5-100 Cleaning a receptacle with a cotton swab NOTICEWhen cleaning a receptacle, insert the cotton swab and turn it slowly in the receptacle.Do not use too much strength because the receptacle may be damaged.5. If optical signals are lost during the operation of a device, use the preceding method toclean the receptacle or the optical connector. In this manner, the possibility ofcontamination can be excluded.Measures to Prevent an Optical Module from Being Burnt1. Before using an optical time-domain reflectometer (OTDR) to test the connectivity or theattenuation of optical signals, disconnect the optical fibers from the optical module.Otherwise, the optical module will be burnt.2.
