NOTEWhen the WDS/Mesh function is enabled on an AP, the blinking frequency of its Wireless indicatorindicates the receive signal strength on the WDS/Mesh connection by default. After you connect an AP toa WDS/Mesh network, you can run the wifi-light { signal-strength | traffic } command on the AC tomake the Wireless indicator blinking frequency indicate receive signal strength or service traffic rate.lwifi-light signal-strength:lIf the Mesh function is enabled on the AP, the blinking frequency of the Wireless indicator reflectsthe weakest signal strength of all neighboring APs.lIf WDS is enabled on an AP, the blinking frequency of the Wireless indicator reflects the strengthof signals received from a WDS AP.lIf the AP works in leaf mode, the blinking frequency of the Wireless indicator reflects thestrength of signals received from a middle AP.lIf the AP works in middle mode, the blinking frequency of the Wireless indicator reflects thestrength of signals received from a root AP.lIf the AP works in root mode, the blinking frequency of the Wireless indicator reflects theweakest signal strength of middle APs.lwifi-light traffic: allows the Wireless indicator to reflect the service traffic volume on the radio.When an AP functions as a Fat AP, the Wireless indicator of the AP can not reflect the signal strength.The AP6310SN-GN does not support WDS/Mesh functions; therefore, the Wireless indicator of theAP6310SN-GN does not indicate the signal strength.1.3 Basic SpecificationsTable 1-7 Basic specifications of the AP3010DN-AGN, AP5010SN-GN, AP5010DN-AGN,AP6010DN-AGN, and AP6010SN-GNItem DescriptionTechnicalspecificationsDimensions (H x W xD)50 mm x 180 mm x 180 mmWeight 0.4 kgSystem memory l256 MB DDR2l32 MB flash memoryPower specifications Power input lDC 12 V ± 10%lPoE power supply: in compliance withIEEE 802.3af/atNOTEThe AP6010DN-AGN and AP6010SN-GN cannotuse the PoE power supply and DC power supplysimultaneously.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 1 Indoor AP OverviewIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.7

Contact Huaweitechnical support engineers or Huaweiagent 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.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 4 Hardware FailuresIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.36
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.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. If the interface remains Down, contact Huawei technical support.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 4 Hardware FailuresIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.37

Step 3 Gently shake the connector and repeat Step 2 to check whether the metal contact strips are ingood contact with the core wires and Ethernet ports, as shown in Figure 5-40.Figure 5-40 Checking the reliability The procedure for testing a crossover cable is the same as that for testing a straight-through cableexcept for the sequence in which the indicators turn on, which depends on the wire connectionsof a crossover cable.The Ethernet cable is qualified if the indicators turn on in the following sequence:At the master (left) section of the tester, the indicators turn on in the sequence of 1-8-G. At theslave (right) section of the tester, the indicators turn on in the sequence of 3-6-1-4-5-2-7-8-G.If the indicators do not come on in this sequence, the Ethernet cable is unqualified.NOTEIf a tester is not available, you can use a multimeter to perform a simple test, as shown in Figure 5-41.Figure 5-41 Testing the connection of an Ethernet cableAP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.61
----End5.1.4 Installing Cable AccessoriesPrecautions for Installing Cable AccessoriesToolsNOTEThe illustrations in this document may differ from actual situations, but the installation methods are thesame. For example, in this document, the adapters of cable connectors have separate interfaces. In the actualsituation, 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.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 are insertedproperly.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 too muchforce, or the screw or adapter may be damaged.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.62
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 the fiberconnectors.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 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 TerminalProcedurelInstall an OT terminal.1.

Engineering Labels for DC Power CablesThese 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 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 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. For details, see Figure 5-93.Figure 5-93 Example of the labels for DC power cablesAP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.108
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 in row B of -48 V bus bar in thecabinet 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, 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, 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 loaded cabinetside is "A01-BGND", it means that the power cable is a BGND that connects BGND copper barin the power distribution box in row A, column 01 in the machine room. Information on thelabels 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 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 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 unnecessary.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.109
Make sure that labels are affixed in the 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 "A01-AC1" indicates that the power cableis connected to the first AC power socket of row A and column 01 in the equipment 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 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 high-power optical signals (caused by an optical time domain reflectometer or self-looptest) are transmitted through an optical module that is used for long-distance transmissionbut no optical attenuator is used, the optical power will exceed the overload power of theavalanche photodiode (APD). Then the 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.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.110
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 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 shakenor 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 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 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.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.111
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.AP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.112
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 □ AnalysisAP3x10xN&5x10xN&5x30xN&6x10xN&7x10xNHardware Installation and Maintenance Guide 5 AppendixIssue 12 (2015-08-05) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.113
