4.1 An device Fails to Be Powered OnFault DescriptionThe SYS indicator of a device is off.Possible CauseslThe power sourcing equipment does not support the PoE function or is faulty.lThe power sourcing equipment is incorrectly configured (the PoE function is disabled orthe power-off time range is improperly set).lThe line is faulty (the network cable or distribution frame is damaged).lThe AP is faulty.Troubleshooting Procedure1. Check whether the power sourcing equipment supports PoE or is faulty.2. Check whether the configuration on the power sourcing equipment causes PoE powersupply errors, such as the PoE function is disabled or the power-off time range is incorrectlyset.3. Check whether the network cable or distribution frame is faulty.4. If the device still cannot be powered on, the device itself is faulty. Contact Huawei technicalsupport engineers or Huawei agent and ask them to replace the device.4.2 An Optical Interface Cannot Turn UpFault DescriptionAfter an optical interface is connected to a remote device through an optical fiber, its LINKindicator is off.Possible CauseslThe optical fiber is faulty.lThe optical module on the optical interface cannot meet the requirements.Troubleshooting Procedure1. Replace the optical fiber and optical module and check whether the optical interface canturn Up. Ensure that the optical module meets the following requirements.2. Determine optical module attributes.lThe optical module has passed Huawei certification.lThe transmission speed of the optical module is the same as the interface speed.lThe wavelength of the optical module is the same as that of the remote optical module.lThe transmission distance of the optical module is suitable for the actual distancebetween the two devices.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 4 Hardware FailuresIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.47
NOTElThe transmission distance of an optical module is 10 km, 15 km, 20 km, 40 km, or 80 km.The optical modules with a longer transmission distance have a higher transmit power. If anoptical module with a long transmission distance is used for short-distance transmission, theoptical interface cannot turn Up because the transmit power is too high. The high transmitpower may even burn the receiver of the remote optical module. To reduce the transmit powerin this situation, use an optical attenuator between the optical module and optical fiber.lOptical modules with different speeds are available, for example, 155 Mbit/s, 622 Mbit/s,and 1.25 Gbit/s. It is recommended that you use an optical module with the same speed asthe optical interface to ensure efficient optical transmission.3.

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 radiuses (R) of cables or fibers must meet the requirementslisted in Table 5-9.Table 5-9 Bending radiuses 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.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.73
Cable or Fiber Bending Radius (R)Fiber R ≥ 40 mm (1.57 in.); Bending angle > 90° NOTEThe letter d indicates the diameter of a cable or fiber.Precautions for InstallationlHold the terminals of cables instead of pulling the cables when installing or removing thecable components.lDo not insert a connector forcibly when the connector is blocked. Pull out the connectorby using a dedicated tool. 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, find out the reason and try again. Do not screw it with 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 fiber connectors that are not in use by using dustproof caps. Remove the dustproofcaps before using the fiber connectors.Requirements for Cable RoutinglTo protect cables, remove the burrs in the cable through-holes or install protective rings inthe holes.lTo ease the connection and to avoid stress, keep slack at cable joints. After connectingmultiple cables to a connector that has multiple interfaces, keep the cables slack to avoidstress generation.lBind or clean cables gently because cable distortion affects signal quality.lKeep cables away from moveable components such as doors.lSharp objects must not be touched in cable wiring to ensure that cables are not damaged.lTo protect power cables, power cables of the active and standby power modules are laidseparately.Installing Power AdaptersInstalling the OT TerminalHuawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.74

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. For example,there is a dividing line between the cabinet number and the chassis number, and another onebetween the chassis number and the slot number. The dividing line is 1.5 mm x 0.6 mm (0.06in. x 0.02 in.) with the color of Pantone 656c (light blue).The cut dotted line helps to fold the label when affixed to the cable, and its size is 1 mm x 2 mm(0.04 in. x 0.08 in.).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.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 (0.008in. x 0.02 in.) around (symmetric on both sides), and the area in the middle is for affixing thelabel, as shown in Figure 5-82.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.107
Figure 5-82 Power cable label Label PrintingThe contents can be printed or written on the labels. Printing is recommended for the sake ofhigh efficiency and eye-pleasant layout.Template for PrintingUse a template to print labels. You can obtain the template from the Huawei local office.The templates are made in Microsoft Word and the following requirements should be met:Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.108
lWhen using the template, you can directly modify the contents of the template. The settingsof centered characters, direction, and fonts should not be changed.lWhen there are too many characters to be filled in, zoom out the characters, but make surethat the printouts 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 the labels, a laser jet printer must be used, although there is no restriction on the modelof the printer. Before printing the label, set up the page and try printing.1. Try printing on ordinary paper with both sides blank. Place the blank paper over the wholepage of label paper, and check whether the page setup conforms to the label layout.2. Make sure the printer properties, such as "paper size" and "direction", have been setcorrectly.lIf the printout conforms to the sheet of labels, print the labels on the label paper.lIf the printout does not conform, adjust the page setup and try printing again until thecorrect printout is produced.The method of 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.

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 page ata 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, the dividinglines and the mark "TO:" should not be covered by the printed characters.lWhen the cells are merged and the printouts are made in multiple lines, avoid covering themark "TO:" when printing the texts. Use the space bar to move the text to the next line.Writing LabelsWriting ToolsTo make sure the printouts are clear and legible, use the black markers instead of ball-point pensto write the labels.In special cases, black ball-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 theoil on the label, which may contaminate the label and blur the words.NOTEThe delivered marker has two nibs. Make sure to use the smaller nib to write the labels.FontFor the sake of easy recognition and good appearance, the font in handwriting should be as closeto a standard typeface (such as Times New Roman) as possible. Table 5-21 shows the standardtypeface.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 clear, distinct, and tidy.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.110

TO:B03 -48V2TO:B03 -48V2CableCable Contents of Engineering LabelsContents of 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.Contents of 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. Figure 5-88 shows the information on both sides ofthe labels affixed to the signal cables.lArea 1 contains the location information of the local end of the cable.lArea 2 (with the mark "TO:") contains the location information of the opposite end of thecable.lArea 3 has been folded up inside the label.Figure 5-88 Printed parts on the label for signal cables 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.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.113
Therefore, the information in Area 1 at one end is the same as the information in Area 2 at theother end of the cable. In other words, the local information at one end is called the oppositeinformation at the other end.Precautions for Using Engineering LabelsWhen using labels, pay attention to the following points:lWhen printing, writing, or attaching labels, keep the labels clean.lSince the label paper is made of moistureproof and waterproof material, ink-jet printersand ink pens are forbidden for printing and writing labels.lLabels should be attached tidily. New-type labels are L-shaped. If they are pasted atincorrect locations or in wrong directions, the appearance of the device is affected.lPower cable ties should be attached in the same positions on power cables, withidentification plates on the same side.lThe positions of "up", "down", "left" or "right" are all based on the viewpoint of theengineering person who works on the label.5.4.2 Engineering Labels for Optical FibersThese labels are affixed to the optical fibers that connect the optical interfaces on the boards ina chassis, or on the device boxes. There are two types of labels for optical cables:lOne is for the fiber that connects the optical interfaces on two devices.lThe other is for the fiber that connects the device and the ODF.Labels for the Optical Fibers Connecting DevicesMeaning of the LabelTable 5-22 lists information on both sides of the labels affixed to the optical fibers that connecttwo devices.Table 5-22 Information on labels affixed to the fiber between two devicesContent Meaning ExampleMN-B-C-D-R/TMN: cabinetnumberM: The cabinet rows from front to back are numberedfrom A to Z.N: The cabinet columns from left to right are numberedfrom 01 to 99.For example, A01 is the cabinet in Row A and Column01.B: chassisnumberNumbered in bottom-up order with two digits, forexample, 01.C: physical slotnumberNumbered in the top-down and left-right order startingfrom 01.

Engineering Labels for DC Power CablesThe labels are affixed to the DC power cables that provide power supply for cabinets, includingthe -48 V, PGND, and BGND cables. Here, the DC power cables also include power cables andPGND cables.The labels for DC power cables are affixed to one side of the identification plates on cable ties.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 the 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 for BGND and PGND to identify the row and columnnumber.MN(BC)-B-BGNDMN(BC)-B-PGND The label only carries location information about the destination direction of the power cablewhile information of the local end is not necessary. 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 correction 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 cablesHuawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.120
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 the cableis -48 V DC supply, which is from the eighth connector on row B of -48 V bus bar in thecabinet on 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 on 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, everyterminal block on the -48 V connector bar has a numeric identification. For example, in the above label 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 which terminal is connected makes no difference. It is only necessary to give the rowand column of the power distribution box, instead of giving the specific serial number of theterminal block on the copper bar. For example, if the label on the loaded cabinet side is "A01-BGND", it means that the power cable is a BGND that connects BGND copper bar in the powerdistribution box on Row A, Column 01 in the machine room. Information on the labels for PGNDcables should be given in a similar way.Engineering Labels for AC Power CablesThe 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 and relatedPGND and BGND cables are covered with an insulating sheath, so the labels need to containonly the word "AC" and the cabinet numbers.The labels for AC power cables are affixed to one side of the identification plates on cable ties.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 led inB: chassis number, numbered in the 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 of thesocket is marked according to the actual situation. If the sockets can beidentified by row numbers and column numbers, they can be numberedfollowing the same rule for the cabinets. If the sockets cannot be identifiedby rows and columns, specify the detailed locations to avoid confusionwith other sockets. The label only carries location information about the opposite equipment and the power socket;information about the local end is not necessary.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.121
Make sure that labels are affixed in correct direction. That is, after the cable ties are bundledonto the cable, the identification plates with the labels should face up, and the text on the labelsin 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 with "A01-AC1" indicates that the powercable is connected to the first AC power socket of Row A and Column 01 in the equipmentroom.lOn the power socket side, the label marked with "B01-AC1" indicates that the power cableis connected 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 Module1. An optical module is not completely installed in position.If the optical module is not completely installed in position and the latch boss is not secured,the device cannot identify the optical module. After the optical module works for a longtime, 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 accumulate onthe fiber pin in the optical module. As a result, the coupling efficiency is reduced, opticalsignals are cut off, or even worse, the surface of the fiber pin is damaged permanently.3. An optical module is burnt.If large-power optical signals (caused by the OTDR or self-loop test) are transmittedthrough an optical module that is used for long-distance transmission but no opticalattenuator is used, the optical power will exceed the overload power of the APD pipe. Thenthe optical module is burnt.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.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.122
Measures to Prevent Loosened Optical Module1. When installing an optical module, insert it into 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 good contactwith the connector on the board. In this case, the link may be connected but optical signalswill be cut off or the optical module will be loosened when the optical module is shook orcrashed.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 this time,the latch boss locks the optical module. After the optical module is inserted, try pulling itout to see if it is installed in position. If the optical module cannot be pulled out, 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 the contamination on thesurface of the optical connector.Figure 5-96 Cleaning optical fibers with special cleaning tissuesNOTEPlace at least three cleaning tissues on the work bench. As shown in Figure 5-96, wipe the end of anoptical 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 in Figure5-97.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.123
Figure 5-97 Installing a protective cap If no protective cap is available, use fibers to protect the optical module, as shown in Figure5-98.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 not coveredwith a protective cap, you need to clean it before using it. Clean a receptacle with a cottonswab, as shown in Figure 5-100. Clean an optical connector with cleaning tissues.Huawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.124
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. Donot 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 of contaminationcan 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. When performing a self-loop test, use an optical attenuator. Do not loosen the opticalconnector instead of the optical attenuator.Precautions1. The optical connector should be vertically inserted in the receptacle to avoid damages tothe receptacle.2. Fibers must be inserted into optical modules of the corresponding type. That is, multimodefibers must be inserted into multimode optical modules, and single mode fibers must beinserted into single mode optical modules. If a fiber is inserted into an optical module of adifferent mode, faults may occur. For example, optical signals will be lost.5.6 Fault Tag*Customer name:Address:Contact person:Tel.: Fax:Category*: □ RMA □ Return □ AnalysisHuawei AP8030DN & AP8130DNHardware Installation and Maintenance Guide 5 AppendixIssue 03 (2015-05-18) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.125
