SeRF Module LEDs
NOTE: The SeRF Module LEDs automatically enter a LED Roll Test sequence (cycle through its colors)
when the SeRF FPGA is loaded (approximately 4 minutes after initial power up) or when a
SeRF synthesizer failure occurs. The LED Roll Test sequence takes approximately two seconds
to complete, and cycles the ALARM, SYNTH, and STATUS LEDs, after which the LEDs begin
normal operation. Additionally, an active SeRF Synthesizer failure causes the same LED
sequencing approximately every minute until the SeRF failure clears.

NOTE: Install the Legacy Dual-Bay 40W RF Module in the lower-most bay in the chassis. If, however, if two Legacy Dual-Bay 40W
RF Modules are present, install the 2100 Module in the lower-most Bay and the 1900 Module in the upper-most Bay.

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page80.
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! This is restricted access equipment and only qualified service personnel should open, service, or
operate this equipment using appropriate tools.
CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using
electrically-powered equipment. To prevent electrical shock, never install or use electrical equipment
in a wet location or during a lightning storm.
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! Exterior surfaces of the Prism Remote Unit may be hot. Use caution during servicing.
CAUTION! This equipment uses a Class 1 Laser according to 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! 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.
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 Prism doors after servicing.

Mounting Cautions
ObservethefollowingcautionswheninstallingtheMountingBracketandwhenhangingaPRUonthe
bracket.
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 mounting a Prism Remote Unit.

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 119). For information on bolting, see "Pole Mount Installation
Using Bolts” on page 46.
