1.2 Warnings
Please read this manual prior to use to become familiar with the product’s numerous features and operating procedures. To
maintain the maximum degree of safety, follow the sequences as outlined.

Before using the product, read all instructions and cautionary markings on the product and on any equipment connected to the
product.
CAUTION – Unless otherwise noted, product usage that is not recommended or sold by the product manufacturer can result in
riskofre,electricshock,orinjurytopersons.
CAUTION – Do not operate the product if it has been damaged in any way. Return damaged products to their manufacturer for
repair or replacement.
CAUTION –
A) Elevated Operating Ambient - if installed in a closed or multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature of 55°C.
B)ReducedAirFlow-Installationoftheequipmentinarackshouldbesuchthattheamountofairowrequiredforsafe
operation of the equipment is not compromised.
C) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
D) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
E) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given
to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
F) The supply input voltage ranges between -58Vdc to -40 Vdc (+/- 0%).
G) Rated Output Power (kW) = Input Voltage (Vdc) *275 (A).

2.0 Introduction
In a split Radio Base Station (RBS) architecture the typical RBS consists of a Base Band Unit (BBU) and Remote Radio
Heads (RRH) connected by cabling. Power to the RRH is provided through copper cables traveling from the base station
to the top of the tower or roof top. This creates a conductive path, making the active equipment at the top and the base of
the site vulnerable to damage by direct lightning strikes. Protection systems installed in front of both the BBU and the RRH
must be able to withstand direct lightning currents in order to protect the sensitive equipment. Raycap’s RRH solutions
featuring Strikesorb®SPDtechnologysignicantlyenhancethereliability&availabilityoftheRRHsitebyprovidingsuperior
electrical protection at the RRH and BBU. PowerPlus is Raycap’s solution for power transmission to the RRH units of a DAS
Telecommunication site. PowerPlus is a system installed at the PSU output that boosts the voltage at the base of a cellular site
to overcome the voltage drop on the DC power cables that provide power to the RRHs.

5. General Description
5.1 Functionality
• The PowerPlus RDIDC-100-3-1U-X system is intended to boost the voltage of a telecom power
supply in order to reduce the current on the power cables. The output voltage of the system remains
constanttoavaluethatisusercongurableduringitsinstallation.
• Byreducingthecurrent,thecablepowerlossesarereducedandthetotalsystembecomesmoreefcient.
• AdditionallythePowerPlusRDIDC-100-3-1U-Xisbenecialwhenoperatingonbatterybackuppower
during a power outage. The PowerPlus RDIDC-100-3-1U-X will maintain a constant output voltage
(ascongured)totheradiowhilethebatterydischarges.Thisallowstheradiotooperateforalonger
period of time while the batteries discharge.
5.2 System Conguration
• The PowerPlus RDIDC-100-3-1U-X system is composed of a mounting rack and up to three
pluggable modules.
• The voltage output of each module is connected to a Raycap Power Distribution Unit (PDU)
model RDIDC-9052-PDU-48.

6. System Management
6.1 Modules
• There is always a Primary module in the rack which controls the proper operation of the complete system.
• When a failure occurs, the Primary module will coordinate the response to this event.
• When the Primary module fails, another Secondary module will take over control of the system and
become the new Primary.
• All modules will display the input and output voltage of the system. The Primary module is indicated
by an “P”characterwhichislocatedattheendoftheinputvoltagevalue(rstlineofthedisplay).

6.2 Module Failure
• When a Secondary module fails the Primary module will raise an alarm. The front panel’s LED will
change from GREEN to RED, the remote contact will change toFailed and the Primary module will
display the “MODULE FAILURE” message.
• After removing the failed Secondary module, the Primary module will search for a newly installed
module.Whendetected,thePrimarymodulewilltransfertheoriginalconguredoutputvoltagetothe
new Secondary module.
• The alarm is cleared after pressing the ‘ENTER’ button on the Primary module for more than 3 seconds.
6.3 Primary Module Failure
• When the Primary module fails another Secondary module will takeover the role of Primary and raise
an alarm. The front panel’s LED will change from GREEN to RED, the remote contact will change to
Failed and the new Primary module will display the “PRIMARY FAILURE” message.
• After removing the module the newly assigned Primary module will search for a replacement module
to be installed. When this occurs, the current Primary module will transfer output voltage to the new
module.ThenewmodulewillbeconguredasanewSecondarymodule.
• The alarm will disappear after pressing the ‘ENTER’ button on the current Primary module for more
than 3 seconds.

• Unscrew the thumb screws on both
sides of module.
• Release the side levers.
• Pull out the device.

7.2 Cold Module Replacement
• Cold Module Replacement is the replacement of a module when the system is powered OFF.
• Everymodulestoresthesettings(conguredoutputvoltage)ofallothermoduleswhichparticipatein
the system.
• When the system boots, all the modules will exchange their stored settings. If the settings between
the modules disagree, the system will change to settings mode and will waiting for new settings
to be input. This is the starting point of the initial settings menu. All the modules will display the
“SETTINGS” message.
• Initially, in an empty system (empty slots), 1, 2 or 3 modules may be plugged in, these may have
random stored settings (Cold Module Replacement). After power on the modules will exchange
their stored settings, if the settings between modules are different, the system will change to
settings mode and it will wait for new settings. This is also a starting point of the initial settings
menu.
7.3 Hot Module Replacement
• Hot Module Replacement is the replacement of a module when the system is powered ON and
operational.
• Every module stores the settings of all other modules in the system.
• When a module fails (Primary module or Secondary module failure) it must be replaced. The
replacement may occur while the system is running. The settings of the replaced module will be
transferred automatically to the new module and the system will continue to operate normally.
• The Hot Module Replacement is recommended instead of Cold Module Replacement because
in Cold Module Replacement the system will prompt for initial settings. Also during Hot Module
Replacement the system operation will not be interrupted.
7.4 Hot Module Replacement: Invalid Module Installation
• Ifasystemisconguredandhas1or2emptyslots,anyhot module installation in any empty slot
is invalid. The invalid module will display the “REMOVE MODULE” message, and the invalid module
must be removed.
• If there is a cold module installation in open slot(s), then the system will prompt for initial settings
during power ON.

8. Module Settings
8.1 Settings Menus
• There are two different settings menus. The initial settings menu and the live settings menu.
• The initial settings menu will appear when the system detects differences between the current
module settings and previous module settings during system boot.
• The live settings menu is enabled when the ‘UP’ and ‘DOWN’ buttons of the Primary module are
pressed simultaneously for more than 3 seconds.
• The initial settings menu and the live settings menu are very simple menus.
8.2 Initial Settings Menu
• The initial settingsmenuwillappearwhenthesystemdetectsconictingsettingduringsystemboot,
or at initial power up. Each module will display the “SETTINGS” message.
• The Primary module is selected by pressing the ‘ENTER’ button of any module (e.g. Slot 1 module).
