The USB2.0 standard is supported. 2 Network cable  The service network cable and PoE input cable cannot be connected to the console port. Otherwise, the AP may be damaged when using PoE power supply.  If the AP needs to connect to the Ethernet, ensure that the Ethernet cable is working properly. If the Ethernet cable is not working properly, for example, RJ45 connectors are short-circuited, the AP may fail to be powered on or fail to work. Before connecting an Ethernet cable to the AP, use the cable test tool to check whether the cable is qualified. If the cable is unqualified, replace it.  For the supported network cable types and length requirements, see Connecting Network Cables. 3 DC power adapter When the AP uses the DC power supply, use a power adapter for power supply; otherwise, the AP may be damaged. 4 RF cable Connects an antenna to an IoT card through a radio cable. 5 Antenna Connects a 2.4 GHz or 5 GHz antenna to the AP to send and receive wireless signals.The port type is N-type female.The port is applicable only to an AP that supports external antennas. 6 Antenna Connects a 5 GHz antenna to the AP to send and receive wireless signals.The port type is N-type female.The port is applicable only to an AP that supports external antennas.  No priorities are distinguished for DC and PoE power supply modes, DC and GE/PoE_IN support HSB.  Two PoE channels have no priority and can serve as HSB for each other when they have the same input power type. When installing a cable, you must make a drip loop to prevent water from flowing into devices along the cable. For the method of making the drip loop, see 5.8 Guide to Making Drip Loops. Pay attention to the following points when bundling the cables:  Different types of cables must be separately routed with the minimum spacing of 30 mm and cannot be entangled or crossed. Cables should be parallel or separated using dedicated separators.  Bundled cables are closely arranged, straight, tidy, and undamaged.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 2 AP Installation Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 21  Cable ties are bound neatly facing the same direction, and those at the same horizontal line must be in a straight line. Cable tie tails should be cut smoothly and evenly.  Labels or nameplates must be attached to the cables after they are installed. Connecting Network Cables Table 2-5 Network cable types supported by Ethernet interfaces and maximum transmission distances Interface Rate Network Cable Type Maximum Transmission Distance GE CAT5e or higher 100 m 2.5GE CAT5e or higher unshielded twisted pair (UTP) 100 m CAT5e or higher shielded twisted pair (STP) 200 m When the transmission distance is greater than 100 m, this network cable can only be used to connect the following switches:  S6720-52X-PWH-SI-ACF  S6720-52X-PWH-SI  S6720-56C-PWH-SI-AC  S6720-56C-PWH-SI  S6320-32C-PWH-SI  S6720-32C-SI-AC  S6720-32C-SI-DC  S6720-32C-PWH-SI-AC  S6720-32C-PWH-SI 5GE CAT5e UTP  100 m (Only the first 30 m of cables is bundled in 6-a-1 mode.)  55 m (All cables are bundled.)  100 m (Each cable is bundled separately.)

AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 2 AP Installation Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 22  Connecting UTP network cables to 5GE interfaces poses high risks and is not recommended. The causes are as follows:  802.3bz requires that the ALSNR value for alien crosstalk between network cables be greater than 0, but the standards for Cat5e and Cat6 unshielded twisted pairs do not specify the required ALSNR value. Therefore, such cables may not meet the crosstalk requirement in 802.3bz, causing severe problems such as continuous packet loss.  According the cabling specification TIA TSB-5021, using Cat5e and Cat6 cables for 5G poses high risks.  Currently, no clear onsite testing or evaluation method is available for checking whether ALSNR of cables conforms to 802.3bz.  If Cat5e and Cat6 unshielded twisted pairs do not meet the 5G requirement, you are advised to replace them with shielded twisted pairs or reduce the rate of interfaces to 2.5G. Connecting Antennas Connect the antennas delivered in the installation accessory package of the AP to the 2.4G/5G RF ports on the AP, tighten the nuts (with a torque of 0.8 N•m), and adjust antenna angles as required. Do not connect the antennas delivered in the installation accessory package of the AP to 5G antenna interfaces. Otherwise, the AP and antennas may be damaged. The 5G antenna interfaces can be connected only to remote antennas through feeder cables. 2.8 Connecting the Security Lock There is a security slot on the device. You can lock the device to an immovable object to prevent theft. The detailed procedures are as follows: 1. Fasten the cable of the security lock to an immovable object around. 2.

AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 36  Do not use connectors if their shells or pins have exposed part or uneven plating, or their pins are lost, broken, or bent.  Do not use connectors that have dirt on their pins or in their jacks or if there are conductors between pins or between pins and the shell. Precautions for Assembly  Use dedicated tools or tools delivered by Huawei and follow the methods given here during assembly.  Hold terminals of cables instead of pulling the cables themselves when installing or removing cable components.  Take 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 using bundling ropes. The inner diameters of the coils should be larger than 20 times the outer diameters of the cables. − When stripping the jackets of cables, avoid damaging the shield layers (braid or aluminum foil), insulation, core conductors, and other jackets that do not need to be stripped. − After assembling cables, cut all visible cross sections of jackets to ensure that the cross sections are arranged neatly. − Do not touch the core conductors of cables with your hands. Terminate exposed conductors in a timely way after stripping off insulation so that the surface of the conductors does not become oxidized.  Take 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. − Cut all the exposed copper wires. − Try to avoid a second crimping of sleeves. − Keep all the conductors clean and aligned.

AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 84 ----End 5.1.3.8 Common Network Cable Faults and Preventive Measures Table 5-12 lists common network cable faults and preventive measures. Table 5-12 Common network cable faults and preventive measures Symptom Cause Preventive Measure  The device cannot be powered using PoE.  The device restarts frequently.  A large number of error packets exist on the device or services are interrupted. A network cable has high resistance or is too long. Before using network cables purchased from other suppliers, use a multimeter or other tools to measure cable resistance. If the resistance of a network cable does not comply with the quality requirement of the PoE standard, as shown in Table 5-13, replace the network cable. Non-standard network cable connectors cause poor contact with device interfaces. Before making a network cable, use a standard go-no go gauge to test the connectors purchased from other suppliers. Replace the connectors if they do not comply with the standard. Wires in a network cable are connected to wrong pins. After a network cable is made, use a conduction tester to measure cable connectivity. For test details, see 5.1.3.7 Testing the Connection of Assembled Cables. A network cable connector is not crimped securely, causing poor contact between the network cable and pins in the connector. When testing a network cable with a conduction tester, gently shake the cable connector and check whether indicators on the conduction tester are in normal state. If indicators 1 to G turn on in a wrong sequence, remake the network cable. The following methods are often used to test network cable resistance, and the test criteria are listed in Table 5-13:  Use a network cable tester (high-end cable tester of Fluke) to measure network cable resistance.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 85  Connect multimeter probes to two ends of each wire in a network cable and check the resistance value on the multimeter.  Connect a network cable to an AP. Use a multimeter to test the resistance between pins 1 and 2 (or between pins 3 and 6, 4 and 5, or 7 and 8) on the other end of the cable. The cable's DC resistance approximately equals a half of the displayed value. Table 5-13 PoE standard requirements for network cable quality Standard Total Resistance of a Network Cable 802.3af ≤ 20 ohms 802.3at Maximum PD power consumption < 12.95 W ≤ 20 ohms Maximum PD power consumption < 25.5 W ≤ 12.5 ohms If an AP is connected to a switch or AC (excluding ACU2), you can run the virtual-cable-test command on the switch or AC to check network cable connectivity.

For example, in this document, the adapters of cable connectors have separate interfaces. In the actual situation, the adapters may have interfaces fixed on equipment. Use dedicated tools provided or specified by Huawei and follow the installation procedure described here. Bending Radius Unless otherwise specified, bending radius (R) of cables or fibers must meet the requirements listed in Table 5-14. Table 5-14 Bending radius of cables or fibers Cable or Fiber Bending Radius (R) Ordinary cable In normal cases, R ≥ 2d. When the cable is connected with a connector, R ≥ 5d. Fiber R ≥ 40 mm (1.57 in.); Bending angle > 90° The letter d indicates the diameter of a cable or fiber. Precautions for Installation  Hold terminals of cables instead of pulling the cables themselves when installing or removing cable components.  Do not insert a connector forcibly when the connector is blocked. Use a dedicated tool to pull out the connector. Install the connector again after you check that the pins are inserted properly.  Before tightening screws on cable connectors, ensure that the connectors are properly connected to their adapters. Tighten the screw with appropriate force using a flat-head or Phillips screwdriver instead of bare hands or an electric screwdriver. If the screw cannot be screwed into the tapped hole, determine the reason and try again. Do not apply too much force, or the screw or adapter may be damaged.  When removing densely aligned cables or fiber connectors, use dedicated pliers such as cable-pulling pliers and fiber-pulling pliers.  Do not twist, bend, stretch, or extrude fibers during installation.  Cover the idle fiber connectors with dust caps. Remove the dust caps before using the fiber connectors.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 95 Requirements for Cable Routing  To protect cables, remove the burrs in the cable through-holes or install protective rings in the holes.  To ease the connection and to avoid stress, keep cable joints slack. After connecting multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid generating stress.  Bind or clean cables gently because cable distortion affects signal quality.  Keep cables away from moveable components such as doors.  Sharp objects must not touch cable wiring to prevent damage to cables.  To protect power cables, route power cables of the active and standby power modules separately. 5.1.5.2 Installing Power Adapters 5.1.5.2.1 Installing the OT Terminal Procedure  Install an OT terminal. a.

Use multiple DC power supply systems and put power equipment in multiple locations.  Adopt a standard DC power supply system, and set the output voltage to the communications equipment within the required range.  Improve reliability of the AC power supply system to reduce the necessary capacity of storage batteries. For small offices, increase the capacity of storage batteries if it is difficult to enhance reliability of the AC power supply system.  The total capacity of the high-frequency switching rectifier must satisfy the power of the communication loading and battery charging. If there are 10 or fewer active rectifier modules, configure one backup module. If there are more than 10 active modules, configure one backup module for every 10 active modules.  Install storage batteries in two or more groups. The capacity is determined by the duration for which the storage batteries must supply power. For most offices, the batteries should be able to supply power for at least one hour.

The cable's shield layer should be connected to the protective ground of the MDF. The MDF should use the same grounding conductor as the cabinet. 4 Do not route signal cables overhead. 5.3.6 Specifications for Laying Out Grounding Cables Table 5-25 shows the specifications for the ground cable. Table 5-25 Specifications for laying out ground cables No. Description 1 The grounding wire should not run parallel to or twist around the signal cable. 2 Bury ground underground or arrange them indoors. Do not route ground cables overhead. 3 Do not connect two cables together to extend the PGND cable, or add any switches or fuses. 4 The PGND cable should be an alternating yellow and green plastic insulated one with a copper core. 5 The neutral line of the AC power cable cannot be connected to the protective ground of transmission and communication equipment in the equipment room. 6 A PGND cable should be as short as possible, with a length of no more than 45 m (147.64 ft). 5.4 Engineering Labels for Cables An engineering label serves as an identifier for on-site installation and maintenance after the installation. Labels on the cables facilitate correct and orderly connection of cables, and easy maintenance after installation. Engineering labels are specialized for power cables and signal cables:

AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 130 Figure 5-154 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 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 2 mm (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 to identify the opposite end of the cable on which the label is affixed. Power Cable Label The label for power cables should be attached to the identification plate on the cable ties that are 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 for affixing the label, as shown in Figure 5-155.

Printing is recommended for the sake of high efficiency and eye-pleasant layout. Template for Printing You 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:  You can modify the contents of the template. Do not change settings of centered characters, direction, and fonts.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 132  If many characters need to be filled in, decrease the font size, but make sure that the printouts are clear and legible. Merging Cells in the Template To 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 Printer To print labels, use a laser jet printer of any model. Before printing labels, set up the page and try printing. 1. Try printing on ordinary paper with both sides blank. Place the blank paper over the whole page of the 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 set correctly. − 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 until the 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. If the warning prompt as shown in Figure 5-156 appears before printing, click Ignore to continue the printing. Figure 5-156 Warning prompt before printing After the page setup has been made correctly, save it for future use. This page setup is only necessary the first time you use the template to print the labels.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 133 Requirements for Feeding the Printer The label paper consists of two layers and has undergone multiple processing procedures such as printing and cutting. No matter what model of printer you use, feed in the labels one page at 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 correct position. Requirements for the Printed Label Make sure that the printed labels satisfy the following requirements:  All the printouts must be on the label, and nothing should be printed on the backing layer of the label page.  Contents in the cells should be aligned in the center. In a single-line printout, the dividing lines and the word "TO:" should not be covered by printed characters.  When the cells are merged and the printouts are made in multiple lines, avoid covering the word "TO:" when printing the text. Use the space bar to move the text to the next line. 5.4.1.4 Writing Labels Writing Tools To make sure the printouts are clear and legible, use black markers instead of ball-point pens to write the labels. If no marker is available, black ball-point pens are allowed, although not recommended. Compared with ball-point pens, waterproof 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 the words. The delivered marker has two nibs. Use the smaller nib to write the labels. Font For the sake of legibility, use standard block letters and numbers as shown in Table 5-26 (Times New Roman). Table 5-26 Standard typeface for handwriting 0 1 2 3 4 5 6 7 8 9 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Determine the size of characters based on the number of letters or digits and ensure that the characters are distinct and tidy. Placement of text on a label is shown in Figure 5-157.

On the labels, there is information (the part after the word "TO:") about the location of the device on the other end of the cable, like the location of control cabinet, distribution box or power socket. Contents of Labels for Signal Cables The two sides of the label affixed on the signal cable carry information about the location of the ports connected to both ends of the cable. Figure 5-161 shows the information on both sides of the labels affixed to the signal cables.  Area 1 contains the location information of the local end of the cable.  Area 2 (with the word "TO:") contains the location information of the opposite end of the cable.  Area 3 has been folded up inside the label. Figure 5-161 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 the cable. The side with "TO:" that is facing outside carries the location information of the opposite end; and the other side carries the location information of the local end.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 137 In other words, the information in Area 1 at one end is the same as the information in Area 2 at the other end of the cable. 5.4.1.7 Precautions for Using Engineering Labels When using labels, pay attention to the following points:  When printing, writing, or attaching labels, keep the labels clean.  Since the label paper is made of moistureproof material, ink-jet printers and ink pens cannot be used to print and write labels.  Labels should be attached neatly. New-type labels are L-shaped. If they are pasted at incorrect locations or in the incorrect direction, the appearance of the device is affected.  Power cable ties should be attached in the same positions on power cables, with identification plates on the same side.  The positions of "up", "down", "left" or "right" are all based on the viewpoint of the engineering person who is working on the label. 5.4.2 Engineering Labels for Optical Fibers These labels are affixed to the optical fibers that connect the optical interfaces on the boards in a chassis, or on the device boxes. There are two types of labels for optical cables:  One is for the fiber that connects the optical interfaces on two devices.  The other is for the fiber that connects the device and the ODF. 5.4.2.1 Labels for the Optical Fibers Connecting Devices Meaning of the Label Table 5-27 lists information on both sides of the labels affixed to the optical fibers that connect two devices.

Here, the DC power cables also include power cables and PGND 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 5-31. Table 5-31 Contents of the label Content Meaning
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 143 Content Meaning MN(BC)-B--48Vn MN(BC): BC is written right under MN. B: chassis number, numbered in bottom-up order with two digits, for example, 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 number of the power distribution equipment like a control cabinet and distribution box, and BC identifies the row and column number of the -48 V connector. If there is no row number or column number, or the connector can be identified without them, BC can be omitted. It is unnecessary to identify the row and column number for BGND and PGND. MN(BC)-B-BGND MN(BC)-B-PGND The label only carries location information about the destination direction of the power cable whereas information about the local end is unnecessary. That is, the label only carries location information about the opposite equipment, the control cabinet, or the distribution box. Table 5-31 lists the information on two -48 V power supplies on the label. The information on other DC 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 bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction. For details, see Figure 5-166. Figure 5-166 Example of the labels for DC power cables The meaning of the label in Figure 5-166 is as follows:  On the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates that the cable is -48 V DC supply, which is from the eighth connector in row B of -48 V bus bar in the cabinet in row A, and column 1 in the equipment room.  On the distribution box side, the label "B03--48V2" indicates that the cable is -48 V DC supply, connected to DC power socket 2 in row B, column 03 in the equipment room. In 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 above label of "A01/B08--48V2", "08" (or sometimes "8") is the numeric identification of the terminal block.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 144 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 to give the row and column of the power distribution box, instead of giving the specific serial number of the terminal 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 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. 5.4.5.2 Engineering Labels for AC Power Cables These labels are affixed to both ends of an AC power cable that provides AC power supply to cabinets, including 110/220 V, PGND, and BGND cables. The 110/220 V AC cables and related PGND and BGND cables are covered with an insulating sheath, so the labels need to contain only 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 5-32. Table 5-32 Label content Content Meaning MN-(B)-ACn MN: serial number of the cabinet or the socket where the power is led in B: chassis number, numbered in bottom-up order with two digits, for example, 01. n: power port number, numbered as 1 to 3 in bottom-up and left-to-right order. Serial number of the socket where the power is led in: the location of the socket is marked according to the actual situation. If the sockets can be identified by row numbers and column numbers, they can be numbered following the same rule for the cabinets. If the sockets cannot be identified by rows and columns, specify the detailed locations to avoid confusion with other sockets. The label only carries location information about the opposite equipment and the power socket; information about the local end is unnecessary. Make sure that labels are affixed in the correct direction. That is, after the cable ties are bundled onto the cable, the identification plates with the labels should face up, and the text on the labels in the same cabinet should be in the same direction, as shown in Figure 5-167.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 145 Figure 5-167 Labels for AC power cables Meaning of the label in Figure 5-167.  On the equipment cabinet side, the label marked "A01-AC1" indicates that the power cable is connected to the first AC power socket of row A and column 01 in the equipment room.  On the power socket side, the label marked "B01-AC1" indicates that the power cable is connected to the first AC power socket in the cabinet of row B and column 01 in the equipment room. 5.5 Guide to Using Optical Modules Common Faults of an Optical Module The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information. You are advised to use Huawei-certified optical modules. Obtain the electronic label of the optical module and contact technical support personnel to confirm whether it is a Huawei-certified optical module. 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 not secured, the device cannot identify the optical module. After the optical module works for 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 accumulate on 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 damaged permanently. 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-distance transmission but no optical attenuator is used, the optical power will exceed the overload power of the avalanche photodiode (APD). Then the optical module is burnt. The preceding faults lead to temporary or long-term cut-off of optical signals; or even cause permanent damages to the optical module, affecting communication services.
AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 146 Measures to Prevent a Loosened Optical Module 1. When installing an optical module, insert it in position. If you hear a click or feel a slight shake, 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 contact with the connector on the board. In this case, the link may be connected but optical signals will be cut off or the optical module will be loosened when the optical module is shaken or hit. 2. Figure 5-168 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 it out to see if it is installed in position. If the optical module cannot be pulled out, it is secured. Figure 5-168 State of the release handle Close the release handle Open the release handle Measures to Prevent Receptacle Contamination 1. Cleaning tissues must be prepared on site. You need to clean the optical connector before inserting it in the receptacle. This protects the receptacle against contamination on the surface of the optical connector. Figure 5-169 Cleaning optical fibers with special cleaning tissues Place at least three cleaning tissues on the work bench. As shown in Figure 5-169, wipe the end of an optical connector from left to right or from right to left on a cleaning tissue, and then move the connector end to the unused part of the cleaning tissue to continue.

AP7052DN&AP7152DN Hardware Installation and Maintenance Guide 5 Appendix Issue 01 (2017-12-29) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 148 Figure 5-173 Cleaning a receptacle with a cotton swab When 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 to clean the receptacle or the optical connector. In this manner, the possibility of contamination can be excluded. Measures to Prevent an Optical Module from Being Burnt 1. Before using an optical time-domain reflectometer (OTDR) to test the connectivity or the attenuation 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 optical connector instead of the optical attenuator. Precautions 1. The optical connector should be vertically inserted in the receptacle to avoid damages to the receptacle. 2. Fibers must be inserted into optical modules of the corresponding type. That is, multimode fibers must be inserted into multimode optical modules, and single mode fibers must be inserted into single mode optical modules. If a fiber is inserted into an optical module of a different 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 □ Analysis
