lIf the cable jacket or insulation cracks after the cable is bent or twisted, discard this cable

and check whether other cables have the same problem. If other cables have the same

problem, replace these cables.

Checking the Appearance of Connectors

lDo not use connectors with visible defects, damage, rust or scuffing.

lDo not use connectors if their shells or pins have exposed part or uneven plating, or their

pins are lost, broken, or bent.

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 themselves 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.

–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.

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.

AP2030DN

–Cut all the exposed copper wires.

–Try to avoid a second crimping of sleeves.

–Keep all the conductors clean and aligned.

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.

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

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

± 10°.

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

lTo ensure conductivity, 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.

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, which depends on 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.

If the indicators do not come on in this sequence, 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, but the installation methods are the

same. 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 5-9.

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

Table 5-9 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°

NOTE

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

Precautions for Installation

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

removing cable components.

lDo 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.

lBefore 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.

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 idle fiber connectors with dust caps. Remove the dust 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 cable joints slack. After connecting

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

generating 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 modules

separately.

5.2 Environmental Requirements for Device Operation

5.2.1 Environmental Requirements for an Equipment Room

Requirements for Selecting a Site for an Equipment Room

When designing a project, consider the communication network planning and technical

requirements of the equipment. Also consider hydrographic, geological, seismic, power

supply, and transportation factors.

Construction, structure, heating and ventilation, power supply, lighting and fire-proof

construction of the equipment room should be designed by specialized construction designers

to suit the environmental requirements of devices. The equipment room should also follow

local regulations concerning the industrial construction, environmental protection, fire safety,

and civil air defense. Construction must conform to government standards, regulations, and

other requirements.

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

The equipment room should be located in a place free from high temperature, dust, toxic

gases, explosive materials, or unstable voltage. Keep the equipment room away from

significant vibrations or loud noises, as well as power transformer stations.

The specific requirements for selecting a site for an equipment room are as follows:

lThe room should be located at a distance of at least 5 km (3.11 mi.) from heavy pollution

sources such as smelting and coal mines. It should be located at a distance of at least 3.7

km (2.30 mi.) from moderate pollution sources such as chemical, rubber, and

galvanization factories. It should be located at a distance of at least 2 km (1.24 mi.) from

light pollution sources such as packinghouses and tanyards. If these pollution sources

cannot be avoided, ensure that the equipment room is upwind of the pollution sources. In

addition, use a high-quality equipment room or protection products.

lThe room should be located away from livestock farms, or be upwind of the livestock

farms. Do not use an old livestock room or fertilizer warehouse as the equipment room.

lThe equipment room must be far away from residential areas. An equipment room that is

not far away from residential areas must comply with equipment room construction

standards to avoid noise pollution.

lThe room should be located far away from industrial and heating boilers.

lThe room should be at least 3.7 km (2.30 mi.) away from the seaside or salt lake.

Otherwise, the equipment room should be airtight with cooling facilities. In addition,

alkalized soil cannot be used as the construction material. Otherwise, equipment suitable

for wet conditions must be used.

lThe doors and windows of the equipment room must be kept closed to maintain an

airtight room.

lUsing steel doors to ensure sound insulation is recommended.

lNo cracks or openings are allowed on the walls or floors. The outlet holes on the walls or

windows must be sealed. Walls must be constructed such that they are smooth, wear-

resistant, dustproof, flame retardant, sound insulated, heat absorptive, and have

electromagnetic shielding.

lThe air vent of the room should be far from the exhaust of city waste pipes, big cesspools

and sewage treatment tanks. The room should be in the positive pressure state to prevent

corrosive gases from entering the equipment room and corroding components and circuit

boards.

lIt is recommended that the room be on or above the second floor. If this requirement

cannot be met, the ground for equipment installation in the room should be at least 600

mm (23.62 in,) above the maximum flood level.

Recommendations for AC Power Supply

The following are recommendations for the AC power supply.

lIf the voltage of the power mains that supply power directly to devices exceeds the rated

voltage by -10% to 5%, or exceeds the voltage range that devices can support, a voltage

regulating device or voltage stabilizing device is required.

lIf the mains do not supply power for the device directly, or if the mains voltage exceeds

the rated voltage by -15% to 10% or exceeds the input voltage range of the DC power

supply, a voltage regulating device or voltage stabilizing device is required.

lA UPS or inverter power supply system is required to provide uninterrupted AC power

to support the telecommunication load.

lIf abnormalities occur on the mains, telecommunication servers should be equipped with

a self-supplied electric generator to support the key telecommunication load. The

capacity should be not less than 150% to 200% of the total uninterruptible power supply.

lStorage batteries are usually installed in a parallel connection of two groups. UPS

storage batteries are generally installed in one group. The redundancy required for the

Type and Structure

Label for Signal Cables

The label for signal cables is L-shaped with fixed dimensions, as shown in Figure 5-81.

Figure 5-81 Label for signal cables

To specify more clearly the position of a cable, use the dividing lines on the label. For

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

another 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 5-82.

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.

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

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:

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 word "TO:" should not be covered by printed characters.

lWhen 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.

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, 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. Use the smaller nib to write the labels.

Font

For the sake of legibility, use standard block letters and numbers as shown in Table 5-21

(Times New Roman).

at the other end of the cable.

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 material, ink-jet printers and ink pens

cannot be used to print and write labels.

lLabels 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.

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 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:

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 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 5-93.

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

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

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 in row B of -48 V bus bar

in the cabinet 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 DC

supply, connected to DC power socket 2 in 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, 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.

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 5-27.

Table 5-27 Label content

Content Meaning

MN-(B)-ACn MN: serial number of the cabinet or the socket where the power is led

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.

5.5 Guide to Using Optical Modules

Common Faults of an Optical Module

NOTE

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.

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

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 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 5-95 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 contamination on the

surface of the optical connector.

Figure 5-96 Cleaning optical fibers with special cleaning tissues

AP2030DN

Hardware Installation and Maintenance Guide 5 Appendix

Issue 05 (2016-07-22) Huawei Proprietary and Confidential

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.

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 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.
