AF
The rated output power of a FT Strand mount is for multiple carriers. As long as the composite power does not
exceed the rated power (20W for North America), derating is not required for multiple carriers. For situations
where regulatory requirements require reduced interference to adjacent band users, the rating would have to
be reduced by 3 dB. This power reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device. Input power is rated at 115/230VAC, 50/60Hz, and should be protected
based on the power and fuse specifications in Chapter 5 of this manual. Power strips should, at a minimum,
conform to this requirement to prevent equipment damage and possible overload.
Federal Communications Commission (FCC)
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
CRF47 part 15 of the FCC rules. This equipment is also certified to CRF47 part 24 (PCS) of the FCC Rules
depending on the band of operation. Changes or modifications not expressly approved by Powerwave Technologies, Inc. for compliance could void the user’s authority to operate this equipment. These limits are
designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
This device complies with the technical standards governing mobile radio devices in accordance with FCC
Rules. This device is intended to facilitate the reception and transmission of mobile radio devices in the cellular, PCS or other mobile services, and its operation by end users or others requires carrier consent under FCC
rules.

Preface
Safety
Any personnel involved in installation, operation, or service of units included in a Powerwave Distributed
Antenna System (DAS) must understand and follow the points below.
Powerwave Nexus FT systems are designed to receive and amplify signals from one
or more base stations and retransmit the signals to one or more mobile stations. And,
also to act the other way round, that is to receive signals from one or more mobile
stations, amplify and retransmit the signals to the base stations. Powerwave Nexus FT
systems must be used exclusively for this purpose and nothing else.
❑
Units supplied from the mains must be connected to grounded outlets and in conformity
with the local prescriptions.
❑
Power supply units supplied from the mains contain dangerous voltage that can cause
electric shock. Disconnect the mains prior to any work in such a unit. Local regulations
are to be followed when servicing such units. Only authorized service personnel are
allowed to service units while the mains are connected.
❑
All RF transmitting units, including Nexus FTs, will generate radio signals and thereby
give rise to electromagnetic fields that may be hazardous to the health of any person
who is extensively exposed close to an antenna.
❑
A lithium battery is permanently mounted on the CU and FON PCBAs. Due to the risk
of explosion, this battery must only be removed from the board by a Powerwave
authorized service technician.
❑
NiCd batteries are mounted on the FON PCBA. These batteries contain environmental
poisonous substances. If replaced, the old batteries should be disposed of as stated in
the local prescriptions.
❑
The FON unit contains a Class 1M laser transmitter that emits 2—4 mW invisible laser
radiation at 1550 nm during operation and is intended for a restricted location. Avoid
direct exposure from a disconnected laser transmitter or fiber cord. For example, do not
view directly with optical instruments (magnifiers) and do not view directly with
non-attenuating optical instruments.
AF
❑
044-05320 Rev A
❑
The FON Unit has this label attached:
❑
Do not power up the FON unit if a fiber cable is not connected to the fiber output UL
port, or if a fiber cable is connected to the port but disconnected at the other end.
❑
Never look at the end of a fiber cable. The 1310nm and 1550nm laser light is not
visible. Always use an instrument, such as a power meter, to detect signaling.

Electrostatic Discharge (ESD)
Nexus FT Strand Mount
Human Exposure to RF Radiation
Safe distances must be kept when working around antennas. The following paragraphs describe the cautions
to be aware of during the installation and maintenance of antenna systems and how to calculate safety
distances needed for RF radiation at different antenna power and frequencies.
Antennas
To be able to receive and transmit signals, a Nexus FT RM ORD is connected to a donor antenna directed
towards the base station and a service antenna directed towards the coverage area. A fiber optic cable from the
base station might, however, be substituted for the donor antenna.
Installation and Maintenance of Antenna Systems
Installation and maintenance of all antenna systems must be performed with respect to the radiation exposure
limits for public areas. The antenna radiation level is affected by Nexus FT RM ORD output power, antenna
gain, and transmission devices such as cables, connectors, splitters and feeders. Also have in mind the system
minimum coupling loss, typically between 25dB and 35dB, is determined by a standard with the purpose to
protect base stations from noise and other performance dropping effects.
Radiation Exposure
Frequency Radiation power
800/900 MHz
1800/1900 MHz
2100 MHz
AF
The World Health Organization (WHO) and International Commission on Non-Ionising Radiation Protection
(ICNIRP) have determined recommendations for radiation exposure. ICNIRP recommends not to exceed the
following radiation power for public exposure:
4.5W/m²
9.0W/m²
10.0W/m²
For antennas larger than 20cm the maximum radiation power can be calculated by using the following formula:
S = Radiation power in W/m²
P = Output power in W
r = Distance between antenna and human in meters
S= P/(4πr2)
Electrostatic Discharge (ESD)
ESD can severly damage essential parts of the equipment if not handled carefully. Parts on
printed circuit board assemblies (PCBA) as well as other parts in the equipment are sensitive
to ESD. Never touch the PCBA or uninsulated conductor surfaces unless absolutely
necessary.
If you must handle the PCBAs or uninsulated conductor surfaces, use ESD protective
equipment or first touch the chassis with your hand. Never let your clothes touch PCBAs or
uninsulated conductor surfaces and always store PCBAs in ESD-safe bags.

Overview
AF
This manual is intended for use by service technicians familiar with similar types of equipment. It contains
service information required for the equipment described and is current as of the printing date. Changes which
occur after the printing date may be incorporated by a complete manual revision or alternatively as additions.
Powerwave Nexus FT SM repeaters work as bi-directional on-frequency amplifiers used to extend coverage
into uncovered areas in wireless mobile systems such as base station fringe areas, tunnels, convention
centers, airports and buildings. It receives, amplifies, and transmits signals to/from a Base Transceiver Station
(BTS) to/from Mobile Stations (MS) with both directions being served simultaneously. Connections to the
Nexus FT SM are made with N-type or 7/16" male connectors.
Nexus FT SMs are microprocessor controlled. Operational parameters, such as gain and power levels are set
using a PC running Powerwave OM-Online software which communicates with the Nexus FT SMs either locally
or remotely via modem. Remote operation can be performed via PSTN or a GSM net. The Operation and
Maintenance System (OMS) provides for Network Operations Center (NOC) configuration and alarm
monitoring.
Nexus FT SMs can be configured in many combinations depending on the wireless system, single or double
system operation, and output power.

Installation
Introduction
This chapter contains unpacking, inspection and installation instructions for installing and powering up the
Nexus FT SM.
Site Survey
Powerwave recommends that a site survey be performed prior to equipment ordering or installation.
Performing a detailed site survey reduces or eliminates installation and turn-up delays. Pay particular
attention to power plant capacity, cooling needs, floor space, and RF/DC cabling/breaker requirements.
Cabinet dimensions and weights are listed in Chapter 5.
Unpacking and Inspection
AF
This equipment has been operated, tested, and calibrated at the factory. Carefully open containers to remove
equipment. Retain all packing material that can be reassembled in the event unit must be returned to the
factory. Perform the following steps:
❑ Visually inspect equipment for damage that may have occurred during shipment. If possible, in the
presence of the delivery person.
❑ Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous
packing material in connectors.
If equipment is damaged, file a claim with the carrier once the extent of any damage is assessed.
If equipment must be returned to factory, please contact factory for a Return Material Authorization (RMA),
see Chapter 4.
Nexus FT SM Location
The Nexus FT SM is designed with a weather proof outdoor cabinet that can be mounted without any kind of
shelter from rain, snow or hail. The same unit can be installed indoors. A preferable site for the Nexus FT SM
is a location free of obstructions, easily accessible and allows for proper air-flow and ventilation.
If a Nexus FT SM is installed outdoors and can be exposed to direct sunshine, it is essential that air circulates
around the Nexus FT SM with no obstacles. The operating temperature must not exceed 131°F (55°C). A
shelter can be used to shade the Nexus FT SM from direct sunshine..
Mounting
The Nexus FT SM is designed for mounting on a cable using the hangar clips attached to the top of the unit.

Connections
This section describes general examples of how to connect the input and output ports on the WRH.
Main Power and Grounding
Local regulations need to be followed for the main power connection. Nexus FT SMs are approved in
accordance with EN and UL/cUL regulations. This is, however, only valid if a classified power cord is used.
For the Nexus FT SM to meet these regulations you must select one of the following classified and approved
cord types:
❑ EN – H 05 W5 - F HMR
❑ UL – AWM Style 2587
❑ CSA– AWM 1 A/B 11 A/B
For outdoor use, the power cord should meet at least IP65 encapsulation requirements. Do not turn the main
power on until you are ready to commission the WRH.
Fiber Optic and RF Connections
WARNING: For Nexus FT SMs supplied from the main power source, the main outlet must be
grounded.
AF
Fiber optic and RF cable connections should be verified both internally and externally before powering up the
equipment. This section illustrates the general internal connections of the Nexus FT SM. Verify these
connections with the as-built drawings and documents for your specific system configuration. Table 3-1 lists
the steps to add the external connections to the Nexus FT SM.

Alarms
Alarm signals from external sensors are received by an ALI or RCI which forwards them to the CU. The RCI is
used if the Nexus FT SM has an RCU, otherwise the ALI is used. The software on the CU can activate
acoustic or visual alarms or direct the alarm to the P33 alarm port for forwarding via an RCU through OMOnline. Alarms can also be handled by the FON. Alarms are configured through OM-Online.
Commissioning
Before proceeding, carefully read the Safety section and check all connections made during the installation.
To fulfill the IP65 weather protective requirements, ensure cable strain relief bushings are properly tightened.
Also, ensure gaskets at cable inlets and on the cabinet are properly fitted and not damaged.
A Nexus FT SM can be configured locally with OM-Online by connecting a standard serial cable from the
COM port on the PC to the P31 PC port (RS-232) located to the right in the cabinet as shown in Figure 3-9.
The P31 PC port is described in Chapter 2. Details on using OM-Online are described in the OM-Online User
Manual.
Initial Startup
To complete the inital start-up of the Nexus FT SM, follow the steps listed in Table 3-3.

Passive Intermodulation (PIM) Testing
PIM is the non-linear effect of passive RF components in a desired RF transmission band. As higher percarrier transmit power levels are applied to duplexed passive RF networks, PIM becomes an increasingly
significant factor in potential receiver desensitization. A PIM tester may be used on the RF network prior to
turn-on and commissioning of the unit, but if a PIM tester is not available, the following may be used:
The following equipment is required to test for PIM:
❑
❑

❑
Anritsu Site eMaster or equivilent RF Spectrum Analyzer
Agilent ESG4432B or equivilent Multi-Signal Generator (or commissioned BTS)
Guarateed/calibrated PIM load capable of handling 20W composite power
Low-PIM RF cable adaptors such as N-N female, Din male to N femaile, DIN-DIN, SMA-SMA
female, and N male to SMA female
❑ Installed and operational Nexus FT SM unit
❑ Installed passive RF network under test
❑ Torque wrenches for DIN and N connectors
Two different types of setup are available, depeding on equipment availability and testing methods.
Figure 3-10 shows PIM testing with two carriers over one Nexus FT SM, and Figure 3-11 shows PIM testing
with one carrier over each of two Nexus FT SMs.
