The AP is transmitting or receiving data

normally, and the signal strength is low.

NOTE

When the WDS/mesh function is enabled on an AP, the blinking frequency of its Wireless LED indicates

the receive signal strength on the WDS/mesh connection by default. After you connect an AP to a WDS/

mesh network, you can run the wifi-light { signal-strength | traffic } command on the AC to make the

Wireless LED 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 LED reflects

the weakest signal strength of all neighboring APs.

lIf WDS is enabled on an AP, the blinking frequency of the Wireless LED reflects the strength

of signals received from a WDS AP.

lIf the AP works in leaf mode, the blinking frequency of the Wireless LED reflects the strength

of signals received from a middle AP.

lIf the AP works in middle mode, the blinking frequency of the Wireless LED reflects the

strength of signals received from a root AP.

lIf the AP works in root mode, the blinking frequency of the Wireless LED reflects the weakest

signal strength of middle APs.

lwifi-light traffic: allows the Wireless LED to reflect the service traffic volume on the radio.

The Fat AP does not support WDS/Mesh functions; therefore, the Wireless indicator of the Fat AP does

not indicate the signal strength.

The AP6310SN-GN does not support WDS/mesh functions; therefore, the Wireless indicator of the

AP6310SN-GN does not indicate the signal strength.

Figure 2-4 Sheet metal mounting brackets

2.4 Determining the Installation Position

When determining the AP installation position, comply with the following rules:

lTry to reduce the number of obstacles, such as walls, between the AP and user terminals.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 2 AP Installation

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

lInstall the AP away from electronic devices that can cause radio interference, such as the

microwave oven.

lInstall the AP in a hidden position that does not affect daily lives and work of residents.

lInstall the AP in a site that is free from leaking or dripping water, heavy dew, and humidity,

and take protective measures to prevent water from flowing into the equipment along the

cable.

Indoor APs are usually mounted on a wall or ceiling using sheet metal mounting brackets. The

installation position is determined by the site survey. There must be at least 200 mm clearance

between the cabling end of the AP and the wall. Figure 2-5 shows space requirements.

Hardware Installation and Maintenance Guide 4 Hardware Failures

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

4.1 An device Fails to Be Powered On

Fault Description

The SYS indicators of an device is off.

Possible Causes

lThe 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 Procedure

1. 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 the

device is powered on, the original power adapter is faulty. Contact Huawei technical

support or Huawei agent through Hotline&Email and ask them to replace the power

adapter.

4. If the device still cannot be powered on, the device itself is faulty. Contact Huawei technical

support or Huawei agent through Hotline&Email and ask them to replace the device.

4.2 An Optical Interface Cannot Turn Up

Fault Description

After an optical interface is connected to a remote device through an optical fiber, its LINK

indicator is off.

NOTE

GE0/0/0 on the AP6610DN-AGN is a combo interface.

Possible Causes

lThe optical fiber is faulty.

lThe optical module on the optical interface cannot meet the requirements.

Troubleshooting Procedure

1. Replace the optical fiber and optical module and check whether the optical interface can

turn Up. Ensure that the optical module meets the following requirements.

2. Determine optical module attributes.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 4 Hardware Failures

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

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 distance

between the two devices.

NOTE

lThe 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 an

optical module with a long transmission distance is used for short-distance transmission, the

optical interface cannot turn Up because the transmit power is too high. The high transmit

power may even burn the receiver of the remote optical module. To reduce the transmit power

in 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 as

the optical interface to ensure efficient optical transmission.

lDo not use connectors if their pins or shells are damaged.

lDo 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

lUse dedicated tools or tools delivered by Huawei and follow the methods given here during

assembly.

lHold terminals of cables instead of pulling the cables when installing or removing cable

components.

lTake the following precautions when cutting or stripping cables:

–Make cables slightly longer than necessary.

–Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the coils 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.

–Clean the exposed jackets. Cut all cables 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.

lTake the following precautions when crimping and connecting cables or connectors:

–The terminals and conductors should be connected tightly after they are crimped. They

should not be moved or turned.

–Cut all the exposed copper wires.

Checking the Appearance of Contact Strips

Context

lTo ensure proper contact between the crimped wires and the wire conductors, the heights

and sizes of the contact strips must be standard and the same.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

lThe contact strips must be parallel to each other, with an offset less than ± 5°. The top

margin of a strip must be parallel to the axis of the connector, with an offset less than ±

10°.

lTo ensure conduction, the surface of the contact strips must be clean.

lThe contact strips must be in good contact with the RJ45 socket. The plastic separators

must remain intact and be aligned.

lThe contact strip blade must extend beyond the ends of the wires. The ends of the wires

must be in contact with the edge of the RJ45. The distance between them must be less than

0.5 mm (0.02 in.).

Procedure

Step 1 Hold the crimped connector, with the front side facing you, and check whether the contact strips

are of the same height. The height should be 6.02 ± 0.13 mm (0.237 ± 0.005). If a measuring

tool is not available, you can compare the connector with a standard connector. Figure 5-32

shows an unqualified piece, and Figure 5-33 shows a qualified piece.

NOTE

All unqualified pieces must be crimped again.

Procedure

Step 1 Feed both connectors of the cable into the ports of the cable tester.

Step 2 After the connectors are properly inserted, turn on the tester. If the indicators from 1 to G turn

on simultaneously, you can infer that the pins work normally and the wires are correctly

connected.

NOTE

Turn the switch to the S position to slow down lighting of the indicators so that you can see the indicators

more clearly, as shown in Figure 5-39.

Step 3 Gently shake the connector and repeat Step 2 to check whether the metal contact strips are in

good 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 cable

except for the sequence in which the indicators turn on. You need to refer to the wire connections

of 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 the

slave (right) section of the tester, the indicators turn on in the sequence of 3-6-1-4-5-2-7-8-G.

Otherwise, the Ethernet cable is unqualified.

5.1.4 Installing Cable Accessories

Precautions for Installing Cable Accessories

Tools

NOTE

The illustrations in this document may differ from actual situations. 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 radiuses (R) of cables or fibers must meet the requirements

listed in Table 5-9.

Table 5-9 Bending radiuses 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.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

Cable or Fiber Bending Radius (R)

Fiber R ≥ 40 mm (1.57 in.); Bending angle > 90°

NOTE

The letter d indicates the diameter of a cable or fiber.

Precautions for Installation

lHold the terminals of cables instead of pulling the cables when installing or removing the

cable components.

lDo not insert a connector forcibly when the connector is blocked. Pull out the connector

by using a dedicated tool. Install the connector again after you check that the pins are

inserted properly.

lBefore tightening screws on cable connectors, ensure that the connectors are properly

connected with their adapters. Use flathead or Phillips head screwdrivers and do not use

too much force. To avoid damaging screws or adapters, do not tighten the screws forcibly.

lWhen removing densely aligned cables or fiber connectors, use dedicated pliers such as

cable-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 dustproof

caps before using the fiber connectors.

Requirements for Cable Routing

lTo protect cables, remove the burrs in the cable through-holes or install protective rings in

the holes.

lTo ease the connection and to avoid stress, keep slack at cable joints. After connecting

multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid

stress 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 laid

separately.

there is a dividing line between the cabinet number and the chassis number, and another one

between the chassis number and the slot number. The dividing line is 1.5 mm x 0.6 mm (0.06

in. 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. The

mark 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 5-82.

Label Printing

The contents can be printed or written on the labels. Printing is recommended for the sake of

high efficiency and eye-pleasant layout.

Template for Printing

Use 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 Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

lWhen using the template, you can directly modify the contents of the template. The settings

of 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 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 the labels, a laser jet printer must be used, although there is no restriction on the model

of 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 whole

page 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 set

correctly.

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 the

correct 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. Select Left for Gutter Position and adjust the values of Top,

Bottom, Left, and Right.

NOTE

If the warning prompt as shown in Figure 5-83 appears before printing, click Ignore to continue the

printing.

Figure 5-83 Warning prompt before printing

After the page setup has been made correctly, save it for future use. This page setup is only

necessary the first time you use the template to print the labels.

Requirements for Feeding the Printer

The label paper consists of two layers. 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.

Requirements for the Printed Label

Make 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 layer

of the label page.

lContents in the cells should be aligned in the center. In a single-line printout, the dividing

lines 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 the

mark "TO:" when printing the texts. Use the space bar to move the text to the next line.

Writing Labels

Writing Tools

To make sure the printouts are clear and legible, use the black markers instead of ball-point pens

to 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 the

oil on the label, which may contaminate the label and blur the words.

NOTE

The delivered marker has two nibs. Make sure to use the smaller nib to write the labels.

Font

For the sake of easy recognition and good appearance, the font in handwriting should be as close

to a standard typeface (such as Times New Roman) as possible. Table 5-21 shows the standard

typeface.

Table 5-21 Standard typeface for handwriting

012345678

Attaching Labels

After printing or writing the label, remove the label from the page and attach it to the signal

cable, or the identification plate of the power cable. The methods for attaching labels are

described in the following sections.

Label for Signal Cables

lChoose the place to attach labels.

The label is attached 2 cm (0.79 in.) from the connector on a signal cable. In special cases

(for example, to avoid cable bending or affecting other cables), other positions are allowed

to attach the labels. 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 labels

Figure 5-86 shows the methods and procedures for attaching labels.

Figure 5-86 Label for signal cables

Power Cable Label

Remove 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 to

only one side of the identification plate. The cable ties are bundled at 2 cm (0.79 in.) from the

connectors, and other positions are allowed in special circumstances.

Cable ties should be bound on both ends of a cable. After the bundling, the finished identification

plate should be on top of the cable in horizontal cabling, or on the right side of the cable in

vertical 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 the

Contents of Engineering Labels

Contents of Labels for Power Cables

Labels 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 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 5-88 shows the information on both sides of

the 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 the

cable.

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 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.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Therefore, the information in Area 1 at one end is the same as the information in Area 2 at the

other end of the cable. In other words, the local information at one end is called the opposite

information at the other end.

Precautions for Using Engineering Labels

When 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 printers

and ink pens are forbidden for printing and writing labels.

lLabels should be attached tidily. New-type labels are L-shaped. If they are pasted at

incorrect 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, with

identification plates on the same side.

lThe positions of "up", "down", "left" or "right" are all based on the viewpoint of the

engineering person who works 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:

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.

5.4.5 Engineering Labels for Power Cables

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Engineering Labels for DC Power Cables

The labels are affixed to the DC power cables that provide power supply for cabinets, including

the -48 V, PGND, and BGND cables. Here, the DC power cables also include 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 5-26.

Table 5-26 Contents of the label

Content Meaning

MN(BC)-

B--48Vn

MN(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 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 for BGND and PGND to identify the row and column

number.

MN(BC)-B-

BGND

MN(BC)-B-

PGND

The label only carries location information about the destination direction of the power cable

while information of the local end is not necessary. That is, the label only carries location

information about the opposite equipment, the control cabinet, or the distribution box. Table

5-26 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 correction 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 5-93.

Figure 5-93 Example of the labels for DC power cables

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

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 cable

is -48 V DC supply, which is from the eighth connector on row B of -48 V bus bar in the

cabinet 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 DC

supply, connected to DC power socket 2 on row B, column 03 in the equipment room.

NOTE

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.

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 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 on Row A, Column 01 in the machine room. Information on the labels for PGND

cables should be given in a similar way.

Engineering Labels for AC Power Cables

The 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 5-27.

Table 5-27 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 the bottom-top order with two digits, for

example, 01.

n: power port number, numbered as 1 to 3 in bottom-top 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 not necessary.

Make sure that labels are affixed in 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 5-94.

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 power

cable is connected to the first AC power socket of Row A and Column 01 in the equipment

lOn the power socket side, the label marked with "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

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 large-power optical signals (caused by the OTDR 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 APD pipe. 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.

Measures to Prevent Loosened Optical Module

1. When installing an optical module, insert it into position. If you hear a click or feel a slight

shake, it indicates that the latch boss is secured.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

109

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 shook or

crashed.

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 it

out 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 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 the contamination on the

surface of the optical connector.

Figure 5-96 Cleaning optical fibers with special cleaning tissues

NOTE

Place at least three cleaning tissues on the work bench. As shown in Figure 5-96, 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.

2. Cover an unused optical module with a protective cap to prevent dust, as shown in Figure

5-97.

Huawei Indoor Access Points

Hardware Installation and Maintenance Guide 5 Appendix

Issue 08 (2014-04-10) Huawei Proprietary and Confidential

Figure 5-97 Installing a protective cap

If no protective cap is available, use fibers to protect the optical module, as shown in Figure

5-98.

Figure 5-98 Using fibers to protect an optical module

3. Cover unused optical connectors with protective caps, as shown in Figure 5-99, and then

lay out fibers on the fiber rack or coil them in a fiber management tray to prevent fibers

from 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 covered

with a protective cap, you need to clean it before using it. Clean a receptacle with a cotton

swab, as shown in Figure 5-100. Clean an optical connector with cleaning tissues.

Figure 5-100 Cleaning a receptacle with a cotton swab

NOTICE

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

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 will occur. For example, optical signals will be lost.
