INSTALL THE PRISM REMOTE UNIT
ThissectiontellsyouhowtoinstallaPrismRemoteUnit(PRU).IfthePRUisalreadyinstalledandyouneedto
addoneormoreRFModules,goto"InstalltheRFModule(s)”onpage84.
PLANNING FOR A PRISM REMOTE UNIT INSTALLATION
BeforeyouunpackthePRU,youshouldfirstplanforwhereitwillbemountedandcollectthetoolsandsupplies
thatarerequiredtomountthePRUandthenconnectittoaPrismsystem.
NOTE: Installation of the Prism Remote Unit may proceed separately from the installation of the corresponding
Host Unit.
Safety Precautions
CAUTION! Do not power on the Prism Remote Unit chassis until instructed to do so in the installation procedures
included in this installation guide.
CAUTION! This is restricted access equipment and only qualified service personnel should open, service, or operate
this equipment using appropriate tools.
CAUTION! This equipment uses a Class 1 Laser per FDA/CDRH rules. Laser radiation can seriously damage the retina
of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver
of any digital unit or exposure to laser radiation may result. An optical power meter should be used to
verify active fibers. A protective cap or hood MUST be immediately placed over any radiating
transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation
exposure. This practice also prevents dirt particles from entering the adapter or connector.
CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using
electrically-powered equipment. Do not perform service on the Prism Remote Unit or its components
in a wet location, if it is raining or snowing, or if impending rain or snow has been observed.
CAUTION! Exterior surfaces of the Prism Remote Unit may be hot. Use caution during servicing.
CAUTION! Contact with overhead cables, especially electric power cables, could cause serious personal injury or
death. Before beginning the installation, check the location of all overhead wires and cables and take
precautions to avoid accidental contact.
CAUTION! Use appropriate lifting equipment when unpacking, moving or installing the Fullband Remote Unit. Do
not stand under the Fullband Remote Unit as it is hoisted into position for installation. A failure of the
lifting equipment could result in serious personal injury.
CAUTION! The location in which the Remote Unit is installed (utility pole, mast, or flat surface) must be able to
support the weight of a fully-populated Fullband Remote Unit; see Table 18 on page 31.
CAUTION! This system is an RF Transmitter and continuously emits RF energy. Maintain 3 foot (91.4 cm) minimum
clearance from the antenna while the system is operating. Wherever possible, shut down the RAN
before servicing the antenna.

Install the Prism Remote Unit
CAUTION! Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends.
Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than
2 inches (5.1 cm).
CAUTION! Always use an Electro-Static Discharge (ESD) wrist strap whenever you work with the Prism Remote Unit
or its components. Make sure that it maintains maximum contact with bare skin. ESD grounding straps
are available with banana plugs, metal spring clips, or alligator clips. To ensure adequate grounding,
connect the ESD wrist strap to any bare metal surface of the Prism Remote Unit chassis (which may
require that you scrape off some of its protective coating), or to the Dual-Ground Connector at the
bottom of the unit. For information on the Dual-Ground Connector, see "Ports and Connectors” on
page 7.
CAUTION! Service personnel must confirm that the perimeter gasket and door-to-door gaskets are in place when
closing the Remote Unit doors after servicing.

CAUTION! Use appropriate lifting equipment when unpacking, moving or installing the Prism Remote Unit. Do not
stand under the Prism Remote Unit as it is being hoisted into position for installation. A failure of the
lifting equipment could result in serious personal injury.
CAUTION! The pole must be structurally sound and able to support the weight of the unit being installed as listed
in Table 19 on page 31.
CAUTION! The hardware used to package the PRU for shipment is not intended for Prism Remote Unit installations
and should be kept with the Prism Remote Unit packaging. Do not use the shipping hardware when

Steel Pole Installation Using Steel Banding
CAUTION! Always wear safety goggles when working with metal banding and when using tensioning tools.
CAUTION! This section describes how to secure a PRU to a steel pole using steel bands. In high earthquake risk
areas, CommScope advises in addition to banding, bolts should be used redundantly to ensure
mechanical mounting capable of surviving severe seismic activity. Typical areas where this attachment
method are suggested are Earthquake Risk Zone 4, per Bellcore GR-63-CORE, section 4.4.1.1. If you have
application specific questions, consult the Wireless Technical Assistance Center (TAC) for technical
assistance (see "DCCS Global Technical Support” on page 124). For information on bolting, see "Pole
Mount Installation Using Bolts” on page 46.

NOTE: Use the following procedure to install the fiber cables using a Hardened Multi-Fiber Optic Connector. If
the PRU that you are installing has a Fiber Pass-Through Connector, follow the procedure in "Option B:
Fiber Pass-Through Connector” on page 62. If the PRU that you are installing has a legacy ProAx
Connector, follow the procedure in "Option C: ProAx Connector (Legacy AC-Powered PRUs)” on page 67.

NOTE: Each SFP utilizes a single fiber optic pair. Each SFP can support up to 12 timeslots with up to 75 MHz of
bandwidth. Each fiber connector on the PRU contains 4 fiber pairs, supporting the use of 4 SFPs. If
additional SFPs are necessary, use the second fiber connector (FIBER 2).

CAUTION! Use extreme caution when working with high voltage AC power. Ensure all power is disconnected
before working on power circuits.
NOTE: All electrical work must comply with local codes and requirements. A locally licensed electrical
contractor is best qualified to perform this work. For additional information, consult with the

NOTE: The power cable is rated for indoor or outdoor use and must not
be placed within electrical conduit as this will impede the cooling
of the cable during usage. The cable run distance to the AC power
source must not exceed 100 feet.

CAUTION! While trying to connect the AC power cable to the PRU AC power port, it is possible for the line terminal
on the cable connector to contact the ground pin on the power port. If the AC cable is energized, this
will result in a direct short to ground for the AC power. To avoid possible personal injury and equipment
damage, always turn the AC power off before connecting the AC power cable to the AC power port.
