Preface
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.

xi
Preface
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.

All tools must be discharged to ground before use.

The anti-static wrist strap and cord must be checked at regular intervals for
their suitability for use.

Preface
Grounding
To comply with EN 60950, the equipment must be connected to a safety
grounding point via a permanent link. Grounding points are located on the product
for this purpose. Always connect the ground cable before fitting other cables. The
product must remain grounded continuously unless all connections to the power
supply and data network are all removed.
If equipment is grounded through a cabinet or rack, make sure it is done so
properly according to the installation instructions.
Power Supply Connection
The equipment is designed to be powered from a -48 V DC supply. Power
connections and installation of associated wiring must be carried out by a suitably
qualified technician.
Only devices that comply with all relevant national safety requirements should be
connected to the unit's power supply inlets. Other usage will invalidate any
approval given to this equipment.
Connection of this equipment to devices that are not marked with all relevant
national safety requirements may produce hazardous conditions on the network.
When the power supply is obtained by a rectifier/safety isolation transformer, the
supply must meet the requirements of EN 60950 providing double/reinforced
insulation between hazardous voltages and SELV/TNV circuits. Any battery must
be separated from hazardous voltages by reinforced insulation.
Indirect Connection
Before indirectly connecting any equipment to another device through a shared
power supply, ALWAYS seek advice from a competent engineer.
Devices that are not marked according to the relevant national safety standards
may produce hazardous conditions on the network.
Product Disposal

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.
Smart MBS RRH-B8 Installation Manual v3.0
©Samsung Proprietary and Confidential
Chapter 1 Before Installation

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.

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.

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.

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 sendreceive 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.

Sector Antenna Installation
The method of sector antenna installation is as follows.
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
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.
