Chapter 1 Safety Description

Safety InstructionsThis section describes the safety instructions related to electricalsafety, antistatic, heavy objects and modules.

Electrical SafetyInstructions

The following are the electrical safety instructions about tools, highvoltage, power cables, holes and lightning:

� Tools

Use special tools rather than common tools for high-voltageand AC operations.

� High Voltage

Danger:

High voltage is hazardous. Direct or indirect contact with highvoltage or main supply using a wet object could result in death.

� Strictly follow local safety rules to install AC power devices.

� Installation staff must be qualified for performing high-volt-age and AC operations.

� Do not wear any watch, hand chain, bracelet, ring or anyother conductive objects during such operations.

� Prevent moisture from accumulating on the equipment dur-ing operations in a damp environment.

� Power Cable

Warning:

Never install or uninstall power cables while they are live. Oth-erwise, the power cable, when contacting a conductor, may re-sult in sparks or electric arc causing a fire or even damage toeyes.

� Make sure of shutting off power supply before installing ordisconnecting a power cable.

� Before connecting the power cable, make sure that the con-necting cable and its label are appropriate for the actualinstallation requirements.

� Drilling Holes

Warning:

It is not allowed to drill cabinet holes without permission.

� Unqualified drilling could damage wiring and cables insidethe cabinet. Additionally, metal pieces inside the cabinetcreated by the drilling could result in a short circuit. Use



insulation protection gloves and first move cables inside acabinet away when drilling is necessary on a cabinet.

� Protect eyes during drilling as dust or flying debris maydamage eyes.

� Clean any debris in time after drilling.

� Lightning

Danger:

Do not perform high-voltage, AC, iron tower or mast operationsin a thunderstorm.

Thunderstorms would give rise to a strong electromagneticfield in the atmosphere. Therefore, the equipment must begrounded and protected in time against lightning strikes.

Antistatic SafetyInstructions Electrostatic:

Static electricity produced by human body can damage static-sen-sitive components on circuit board, such as large-scale integratedcircuits.

� Friction caused by human body activities is the root cause ofelectrostatic charge accumulation. Static voltage carried by ahuman body in a dry environment can be up to 30 kV, and canremain there for a long time. An operator with static electricitymay discharge electricity through a component when he/shetouches the conductor and causing damage.

� Wear an antistatic wrist strap (the other end of wrist strap mustbe well grounded) before touching the equipment or holdinga plug-in board, circuit board, Integrated Circuit (IC) chip orother devices, to prevent human static electricity from damag-ing sensitive components.

� A resistor over 1 MΩ should be connected in series on the cablebetween the antistatic wrist strap and the grounding point, toprotect the operator against accidental electric shock. Resis-tance over 1 MΩ is low enough to discharge static voltage.

� The antistatic wrist strap used must be subject to regularcheck. Do not replace the cable of an antistatic wrist strapwith any other cables.

� Do not contact static-sensitive modules with any object thateasily generates static electricity. For example, friction of pack-age bag, transfer box and transfer belt made from insulationplastic may cause static electricity on components. Dischargeof static electricity may damage components when they con-tact a human body or the ground.

� Modules should only contact materials such as an antistaticbag. Keep modules in antistatic bags during storage and trans-portation.

� Discharge static electricity of the test device before use, thatis, ground the test device first.


Chapter 1 Safety Description

� Do not place the module near a strong DC magnetic field, suchas the cathode-ray tube of a monitor. Keep the module at least10 cm away.

Hoisting HeavyObjects

Warning:

When hoisting heavy objects, ensure that nobody is standing orwalking under the hoisted object.

� Ensure the hoister can meet hoisting requirements when dis-assembling heavy equipment, or moving and replacing equip-ment.

� The installation personnel must be duly trained and qualifiedfor hoisting operations.

� Hoisting tools must be inspected and complete before service.

� Make sure that hoisting tools are fixed firmly on a sufficientlysecured object or wall before the hoisting operation.

� Give brief oral instructions during hoisting operations to pre-vent any mishap.

Unplugging/Plug-ging a Module

� Never plug a module with excessive force, to ensure that thepins on the backplane do not get deformed.

� Plug the module right into the slot and make sure module cir-cuit faces do not contact each other lest any short circuit mayoccur.

� Keep hands off the module circuit, components, connectorsand cable trough when holding a module.

Other SafetyInstructions Note:

Do not perform maintenance or debugging independently, unlessa qualified person is present.

� Perform an airtight test before RRU delivery, and prohibit dis-assembling the RRU on site.

� Replacing any parts or making any changes to the equipmentmight result in an unexpected danger. Therefore, be sure notto replace any parts or perform any changes to the equipmentunless authorized otherwise.

� Due to that RRU is in high temperature during running, the RRUshould be installed in some regions out of operators' reach orstrictly restricted.

� Contact ZTE office if you have any question, to ensure yoursafety.

Making Ethernet CablePrerequisites Prepare the appropriate network cables, RJ-45 connectors (crystal

head) and cable-making tools, which include:

� Millimeter ruler

� Network cable plier

� Electrical knife or twisted pair stripper

� Network cable tester

Context Category 5/5e cable is usually selected to make Ethernet cable.The mapping relationship between serial No. and color of networkwire pair is unique.

� Color of the first wire pair is white/blue and blue.

� Color of the second wire pair is white/orange and orange.

� Color of the third wire pair is white/green and green.

� Color of the fourth wire pair is white/brown and brown.

There are 8 pins for RJ-45 connector. Signal description of con-nector pins is shown in Table 16.

If the network cable is used to connect DTE (Data Terminal Equip-ment) and DCE (Data Circuit Terminating Equipment), straightEthernet cable is adopted. If the network cable is used to connectDTE and DTE, cross-over Ethernet cable is adopted, as shown inFigure 60.

FIGURE 60 WIRING ARRANGEMENT OF STRAIGHT/CROSS-CONNECTETHERNET CABLE

Steps 1. Use electrical knife or twisted pair stripper to peel off about20 mm of external sheath at network cable end to expose fourwire pairs.

2. Arrange wire pairs of the cable. Matching sequence of wirepairs is 1–2, 3–6, 5– 4, 7– 8, as shown in Figure 61. As the con-nector bending may damage the wire pairs inside the sheath,at least 8 mm of wires inside the sheath must be arranged par-allel to each other, forming a flat part. The remaining crossingpart of the wires is oval.


Chapter 10 Cable Making

FIGURE 61 ARRANGE WIRE PAIRS

3. Untwist the exposed wires to make them parallel to each other.Matching sequence of wire pairs is the same as in Step 2, ex-cept that positions of Wire 6 and Wire 4 are exchanged. Inthe cable sheath, untwisted wires should not exist, as shownin Figure 62.

FIGURE 62 UNTWISTED WIRES

4. After trimming the wire (to keep the wires neat without flyingwires), the length of exposed wires is about 14 mm. No cross-ing should exist at the cable end of (10±1) mm, estimatedfrom the end of exposed wire. Positions of Wire 6 and Wire 4are exchanged within 4 mm out from sheath end, as shown inFigure 63.

FIGURE 63 WIRES 4 AND 6 IN SWAP PLACE



5. Before mounting RJ-45 connector to the network cable,Sheathe the cable with 8P8C sleeve. The direction arrange-ment of 8P8C sleeve is shown in Figure 64.

FIGURE 64 8P8C SLEEVE

6. Insert the wires at End A into RJ-45 connector. Ensure that allwires reach the innermost of the RJ-455 crystal head, wherewire copper core can be seen. The wrapped length of RJ-45crystal head in 8P8C sleeve should be at least 6 mm, as shownin Figure 65.

FIGURE 65 RJ–45 CONNECTOR

7. Crimp the RJ-45 connector with the special crimping pliers tomake the pins of RJ45 connector in good contact with wires.If the spring plate of RJ-45 connector is not in place, its highposition may damage the RJ-45 socket. As specified in theFCC standards, the crimped depth of the spring plate of RJ-45connector should be between 5.89 mm ~ 6.15 mm, as shownin Figure 66.



FIGURE 66 CRIMP CONNECTOR

8. Slightly pull the network cable to see if the RJ-45 connector istightly crimped to the network cable. The crimped cable endis shown in Figure 67.

FIGURE 67 CRIMPED CABLE END

9. Sheathe the RJ-45 connector with 8P8C sleeve, as shown inFigure 68.

FIGURE 68 SHEATHED CABLE END

10. Follow Step 1~9 to make the other end of the cable accordingto the wiring requirements of network cable. After making bothcable ends, label the network cable, as shown in Figure 69.

END OF STEPS

Postrequisite Test the cable quality after cable-making.

1. Use network cable tester to check the wiring arrangement atboth cable ends. Check if open circuit, short circuit, or badcontact exists.

2. Check whether the crimping depth of the spring plate of RJ-45connector meets the requirements. For unqualified depth, re-make the cable.

Making E1/T1 Trunk CableConnector

Context The E1/T1 cable connecting BBU and BSC should be made on site.Connect one E1/T1 cable end to BBU data cable or the correspond-ing interface on LPU. For the other cable end, select an appropriatecoaxial connector according to DDF port or the configured trans-mission equipment of the BS; then mount the coaxial connectorto the 75 Ω coaxial cable; finally connect the cable to the corre-sponding interface on DDF or transmission equipment.

Note:

In this topic, the making of E1 cable (on cable end is CC4Y-J32connector; the other cable end is the coaxial connector intendedfor DDF) is presented as an example. The cable processing methodcan be used as a reference when making other cables and connec-tors.

Steps 1. Make CC4Y-J32 Connector of E1 Cable.

i. CC4Y-J32 RF coaxial connector components, as shown ina) of Figure 70.

ii. Apply heat shrink tube, Component 1, and Component 2onto the cable. Peel off the sheath at cable end to exposecore wire. Apply tin to the core wire. Unfold the shieldinglayer so that the crimped part of the connector can be in-serted, as shown in b) of Figure 70.



iii. After soldering the core wire, Component 2 and Component3 are jointed together, as shown in c) of Figure 70.

iv. Install Component 1, and use a special tool to crimp it, asshown in d) of Figure 70.

v. Apply the heat shrink tube to the crimped Component 1.Use a hot-air dryer to heat up the tube so that the tube isfixed together with the component.

FIGURE 70 ASSEMBLY OF CC4Y-J32 COAXIAL CONNECTOR OF E1 CABLE

2. Make coaxial connector of E1 cable intended for DDF.

E1 cable coaxial connector for DDF is shown in Figure 71.

FIGURE 71 COAXIAL CONNECTOR OF E1 CABLE FOR DDF

Cable-Making Method

i. Peel off 14 mm sheath, as shown in a) of Figure 72.



ii. Put onto the cable the following items in turn: cable endsleeve, heat shrink tube, and crimping tube. Turn theshielding net inside out manually or with a net-lifting tool.Peel off the inner insulation layer to expose 3 mm innerconductor, as shown in b) of Figure 72.

iii. Inset the processed cable end to the cable connector. Makesure that core wire should thrust into the solder pin of theinner conductor. Then solder the joint together and trimthe shielding net. The remaining length of the shieldingnet is 6 mm, as shown in c) of Figure 72.

iv. Inset the crimping pipe and shielding net deep into the ca-ble connector, as shown in d) of Figure 72.

v. Use a crimping plier to press the crimping tube into a hex-ahedron, as shown in e) of Figure 72.

vi. Apply the heat shrink tube to the crimped crimping tube.Use a hot-air dryer to heat up the tube so that the tubeis fixed together with the crimping tube. Finally install thecable end sleeve, as shown in Figure 72.

3. Crimping tube4. Crimping plier

3. Check trunk cable.

The inner conductor of the trunk cable should be soldered wellwith the inner conductor of the coaxial cable.



The inner conductor and the external conductor of the two con-nectors of the trunk cable work well. The inner conductor andexternal connector should not form short circuit.
