Personal and Product Safety

This product safety information includes European directives, which you must

follow. If these do not apply in your country, please follow similar directives that

do apply in your country.

Electrical

The product is designed to operate from a -48 V DC supply and is therefore

classified as Safe Extra Low Voltage (SELV) equipment.

All structural parts are grounded and all input and outputs have built-in isolation

from the network. All input and output ports that connect to external power

sources are designed to meet relevant national safety requirements.

The product contains hazardous energy levels as defined by EN 60950. Care must

be taken when maintaining this equipment as injury to personnel or damage to the

equipment could result from mistakes. Maintenance should only be carried out by

trained and competent engineers who are familiar with the relevant procedures and

instructions.

Lasers

The product is fitted with optic modules rated as Class 1 radiation-emitting devices

under EN 60825-1. During installation, operation, and maintenance, never look

into the end of an optical fiber directly or by reflection either with the naked eye or

through an optical instrument. Do not operate equipment with exposed fiber

connectors-cover these with fiber cables or blanking caps. Do not remove

equipment covers during operation unless requested to do so in the documentation.

Carry out normal safety precautions when trimming fibers during installation.

Manual Handling

Care should be taken when handling equipment. Give due consideration to the

weight of the equipment, the physical capability of the individual(s) handling the

equipment, and movements such as twisting, bending and stooping, which could

lead to skeletal and muscular injuries.

Installation

Installation must be carried out by trained and competent engineers only. All

relevant safety measures should be taken to ensure equipment is not connected to

live power and transmission sources during installation. Equipment must be

correctly installed in order to meet the relevant safety standards and approval

conditions.

Each power feed to the unit requires a separate fused feed from the provided

power supply. The cable between the power distribution point and the installed

equipment must have a minimum cross-sectional area of 2.5 mm2.

Preface

Smart MBS RRH-B8 Installation Manual v3.0 xii

©Samsung Proprietary and Confidential

Rack-mountable equipment must be placed in a standard 19-inch rack and secured

with the appropriate fixings as detailed in the installation manual.

Maintenance

Maintenance must only be carried out by a suitably trained and competent

technician. All safety instructions must be carefully observed at all times.

Equipment covers should not be removed while live power and transmission is

connected unless in a controlled environment by trained technicians.

Fire

The product is powered from a -48 V DC supply. To protect against fire, the

equipment is fused.

Environment

The product must be operated in an environment with the specified relative

humidity and ambient temperature ranges.

Keep all liquids away from the equipment as accidental spillage can cause severe

damage.

Cooling

The product cools down by its own set of cooling fans housed in a fan module.

Each fan module detects a fan that is not operating normally. LEDs on the front

panel of the fan tray provide an alarm indication in the event of fan failure.

In the event of fan failure, take urgent remedial action to restore full cooling

capacity.

Take appropriate measures to ensure that fan modules do not start spinning during

repair and maintenance procedures.

Anti-Static Precautions

The circuit boards and other modules in the product are sensitive to and easily

damaged by static electricity. If any card or sub-assembly is removed from the unit,

the following anti-static precautions must be observed at all times:

 Service personnel must wear anti-static wrist straps.

 Circuit boards and sub-assemblies must be placed on ground conductive mats

or in conductive bags.

connector of the system or an auxiliary device after cable path inspection and cable

cutting have been completed.

Follow these guidelines when installing a cable.

 Be careful not to damage the cable.

 If the cable is damaged, cut out the damaged section before installing.

 Run the cable so that it is not tangled. In particular, when installing a cable

from a horizontal section to a vertical section, be careful not to reverse the

upper and lower lines of the cable.

 Always use the maximum curvature radius possible, and make sure that the

minimum curvature radius specification is complied with.

 If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible

pipe, and cable rack, etc.

Cable Binding

Cable binding involves fixing and arranging an installed cable using binding

strings, cable ties, binding lines, and ram clamps, etc.

Follow these guidelines when binding a cable.

 Be careful not to damage the cable during binding.

 Use appropriate cable binding tools according to the target location (indoor or

outdoor, etc.) and the use of the cable (power cable, optical cable, RF cable,

etc.).

 Do not let the cutting section of a cable tie and binding line, etc. be exposed to

the outside. This may cause damage to cables or personal injury. Make sure

that the cutting sections of cables are not exposed to the outside.

 Trim the binding string so that you have about 1.97 in. (5 cm) of string left

from the knot. And insert the remaining string into the knot and make sure the

knot does not loosen.

 If there is a potential danger of contact failure in a connector connection due to

tension, install the cable in the shortest distance.

Connector Attachment

Connector attachment involves assembling a connector to an installed cable or to a

device on the site.

Follow these guidelines when attaching a connector.

 Make sure you are fully aware of the connector assembly method before

assembling a connector. Assemble the connector in accordance with its pin

map.

 Each connector has a hook to prevent its core positions from being changed.

 Use a heat shrink tube at a connector connection for cables that are installed

outdoor, such as RF cables, to prevent water leakage and corrosion from

occurring at the part exposed to the outside.

 Connect each cable of the connector assembly in a straight line.

Chapter 1 Before Installation

Smart MBS RRH-B8 Installation Manual v3.0 9

©Samsung Proprietary and Confidential

 Be careful when connecting a cable not to trigger contact failure at a connector

connection due to tension.

Identification Tag Attachment

Identification tag attachment involves attaching a marker cable tie, nameplate, and

label, etc. to the both ends of a cable (connections to a connector) to identify its

use and cabling path.

Follow the Cable labeling standards as below;

Category: Full Wrap, Full Flag, Half Flag, etc.

Follow these guidelines when attaching an identification tag.

 When installing a cable outdoor, use relief engraving and coated labels, etc. to

prevent markings from being erased.

 Since the form and attachment method for identification tags are different for

each provider, consult with the provider before attaching them.

When connecting the cables, always connect the ground cable first. If worker

contacts the equipment, connect a cable or perform maintenance without

connecting the ground cable, the system can be damaged or a worker may be

injured due to static electricity and short circuit.

When cutting the cable after installation, make sure that the connector is

disconnected. Installation of the cable with the connector connected to the system

may cause contact failure or damage to the connector assembled to the system and

the cable due to cable tension or the electrician’s mistakes

When installing, take care not to overlap or tangle the cables; also, consider future

expansion. Install the DC power cable and data transmission cable away from the

AC power cable to prevent electromagnetic induction.

The cable works require knowledge for the cabling works such as cable

installation/binding.

Chapter 1 Before Installation

Smart MBS RRH-B8 Installation Manual v3.0 10

©Samsung Proprietary and Confidential

After Installation

 Cover the cable hole on the floor with a solid cover.

 Remove all installation residues; clean the area.

The optical module and cable used in the system emit bright laser beams.

Always handle them with care as there is risk of serious injury if the eyes are

exposed to the laser beam of the optical cable.

While cleaning the power supply device, take caution that the device does not

come in contact with alien bodies that may cause power failure.

When you install the antenna, the antenna must be within the protective angle

(left/right side 45° each from the central axis) to prevent the antenna from

lightning damage.

Check whether the system is turned off before connecting or disconnecting an RF

cable connector to or from the RRH-B8 RF port and the RF antenna.

When connecting the RF cable between RRH-B8 RF port and RF antenna, each

port and the RF cable connector should be tighten by 8 lbf·ft (110.4 kgf·cm)

torque to minimize influence of PIMD.

Use a flare nut wrench (Hexagon: 7/8 in.) when connecting/disconnecting the RF

Checking Feeder line Connection

After connecting the feeder line, perform the continuity test and feeder cable return

loss to check if the feeder cable is changed and measure VSWR of antenna and

feeder cable.

Take measurements for the sections ①-② for all of the cables.

The standing wave ratio must be equal to or less than the reference value. If not,

the cable must be removed, measured for each section again, and necessary actions

be taken.

The voltage standing wave ratio (VSWR) of the cable and connector between the

system’s RF port to the antenna port must be smaller than 1.5 (return loss: 14 dB).

If a separate standard has been established with the career, the established standard

will take precedence.

Cautions for the connecting a power cable to a connector are as follows:

- Place the grooves of a cable side connector on the protrusions of a system side

connector to fit into each other and connect them by turning a coupling nut on the

top of the cable side connector. If the connectors are not aligned in a line, the

connectors can be damaged when connecting the connectors.

- Do not connect the power cable to the connector with excessive force as the

connector may be damaged.

- Do not forcefully pull the power cable or bend it beyond the allowed radius of

curvature when fixing to the connector.

To ensure stability in power supply, a circuit breaker must be installed on the

power cable connected to the rectifier (or power distributor).

Capacity of -48 VDC circuit breaker is 32 A.

Installation

Cautions when Installing a Sector Antenna

Precautions of antenna installation are as follows.

 Sector antennas should be installed vertically. (± 1)

 Antenna is the precise material, so be careful not to make damage or form

change.

 When moving antenna, use the tool suitable to rating. In addition, use the rated

carrying device which is at least 200 % or more than antenna considering the

stability.

 Be careful not to give too much strength to the antenna.

 If it rains, suspend connecting the feeder cable and antenna.

 Fix it after adjusting the direction of antenna exactly.

 Distance between steel tower and antenna and the distance between send-

receive antennas are based on the antenna layout.

 Attach the antenna on the position specified in the drawing.

 Install the antenna not to make a feature change of the antenna considering the

direction of the radiation

 When connect the connector to the antenna, not making the alien substance

flowed and is not under the influence of PIMD.

 Measure VSWR of all antennas and the value should be within the regulated

value.

Appendix B Sector Antenna Installation

Smart MBS RRH-B8 Installation Manual v3.0 94

Sector Antenna Installation

The method of sector antenna installation is as follows.

1 Put up an antenna pole and insert the sector antenna into the antenna pole

using a fixing clamp.

2 Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and

bottom.

3 After tightening the fixing clamp, adjust the antenna up/down (tilt) depending

on the signal strength. The bolt of the guide clamp must be loosened, so the

antenna angle can be adjusted.

4 After setting the antenna angle, fasten the bolt of the guide clamp, which was

loosened previously. Regarding the nut, the double nut mounting should be

used to prevent the nut from coming loose.

Tower Ground Construction

1 Install a Tower Ground Bar (TGB) that will be used to ground a feeder cable

onto the tower.

If the height of the tower is more than 65.62 ft (20 m), two or more TGBs

should be installed (onto the lower and upper sections of the tower). If the

tower is 65.62 ft

(20 m) or less, one TGB should be installed. Since the TGB installation

location and the number of TGBs to be installed can differ depending on the

system environment and provider’s standards, consult your service provider.

2 Each TGB should be grounded and separated from other grounds. If there is an

existing ground bar or ground cable for TGB, install the TGB by branching

from it using a ground cable (AWG2, GV 25 mm2 × 1C) ground cable.

3 Fasten the Ground Kit (feeder cable grounding assembly) to the TGB ground

terminal and the tower hole using the pressure terminal hole attached at the

end of the ground kit’s ground cable.
