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.
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.
Chapter 1 Product Description Introduction This manual contains information and procedures for installation, operation, and maintenance of the Nexus FT Strand Mount repeater, referred to in this manual as the Nexus FT SM.
Overview Nexus FT Strand Mount Chassis Design Enclosure AF T The Nexus FT SM is housed in an aluminum enclosure, approved for outdoor use. The enclosure contains the repeater circuitry, with 2 hanger clips for positioning and securing the Nexus FT SM repeater along a cable.
Chapter 2 Controls, and Indicators Introduction This chapter contains descriptions of the controls, indicators and connectors for the Nexus FT SM. AF T Indicators R Figure 2-1 External Indicators D Two LEDs, shown in Figure 2-1, are located on the front cover to provide easy identification of a fault in the system. The amber operation LED lights up approximately 15 seconds after the main power is switched on. When the LED is steady, the Nexus FT SM is ready for operation.
Software and Hardware Compatibility Nexus FT Strand Mount Table 2-1 FON Connectors Port Description P101 SMA, electrical RF input port (to the optical TX port) P102 SMA, electrical RF output port (from the optical RX port) P103 SMA, electrical RF output port (15dB below the P102 port) RX DIN/APC, optical input port (to the P102 and P103 RF ports) TX DIN/APC, optical output port (from the P101 RF port) P104 Used only for development and debugging P105 4-pin male, door LED indicators.
Chapter 3 Installation Introduction This chapter contains unpacking, inspection and installation instructions for installing and powering up the Nexus FT SM. Site Survey T 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.
Connections Nexus FT Strand Mount 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.
Nexus FT Strand Mount Connections Nexus FT SM D R AF T Figure 3-6 illustrates the connections for the Nexus FT SM.
Optional Connections Nexus FT Strand Mount Optional Connections 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.
Chapter 4 Maintenance Introduction This chapter contains periodic maintenance and performance test procedures for the WRH. Periodic Maintenance Periodic maintenance requirements are listed in Table 4-1, as well as the intervals at which the tasks should be performed. Table 4-1 Recommended Periodic Maintenance Interval Action Inspection of cables and connectors 12 months Inspect power, RF and Fiber cables for signs of damage or wear (frayed insulation, cracks, punctures, etc.
