4.1 An device Fails to Be Powered OnFault DescriptionThe SYS indicators of an device is off.Possible CauseslThe power switch on the device is turned off.lThe power cable is not securely connected to the device.lThe power supply unit has failed.–If the device connects to an external power source, its power adapter may fail.–If the device has a built-in power supply, the device itself may be faulty.Troubleshooting Procedure1. Check that the power switch is on.2. Check that the power cable is securely connected to the device.3. Check whether the power supply is normal.lIf the device uses a power adapter, replace the power adapter with a normal one. If thedevice is powered on, the original power adapter is faulty. Contact Huawei technicalsupport or Huawei agent through Hotline&Email and ask them to replace the poweradapter.4. If the device still cannot be powered on, the device itself is faulty. Contact Huawei technicalsupport or Huawei agent through Hotline&Email 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.NOTEGE0/0/0 on the AP6610DN-AGN is a combo interface.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.Huawei Indoor Access PointsHardware Installation and Maintenance Guide 4 Hardware FailuresIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.34
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.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.

The rectangle part with characters is attached facing right or downward,as shown in Figure 5-85. The details are as follows:–The identification card is to the right of the cable in vertical cabling.–The identification card should be downward when you lay out the cable horizontally.Figure 5-85 Text area of the label lProcedure for attaching labelsFigure 5-86 shows the methods and procedures for attaching labels.Huawei Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.98
Figure 5-86 Label for signal cables Power Cable LabelRemove the label from the backing page, and attach it to the identification plate on the cable tie.The label should be attached to the rectangular flute on the identification plate, and attached toonly one side of the identification plate. The cable ties are bundled at 2 cm (0.79 in.) from theconnectors, and other positions are allowed in special circumstances.Cable ties should be bound on both ends of a cable. After the bundling, the finished identificationplate should be on top of the cable in horizontal cabling, or on the right side of the cable invertical cabling, as shown in Figure 5-87. The details are as follows:lThe identification card is to the right of the cable in vertical cabling.lThe identification card is on the top of the cable in horizontal cabling. Make sure that thelabel is facing out.Huawei Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.99
Figure 5-87 Binding the label for the power cableThe identification card is on the top of the cable in horizontal cabling. The identification card is to the right of the cable in vertical cabling. 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 Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.100
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.

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-top order with two digits,for example, 01.N: power socket number, numbered as 1 to 3 in the bottom-top 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 Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.107
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-top order with two digits, forexample, 01.n: power port number, numbered as 1 to 3 in bottom-top 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 Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.108
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 cables 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.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.Huawei Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.109
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 Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.110
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 Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.111
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 will occur. For example, optical signals will be lost.5.6 Fault Tag*Customer name:Address:Contact person:Tel.: Fax:Category*: □ RMA □ Return □ AnalysisHuawei Indoor Access PointsHardware Installation and Maintenance Guide 5 AppendixIssue 08 (2014-04-10) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.112
