INSTALLTHERFMODULE(S)

ThefollowingsectionsguideyouthroughtheinstallationofanRFModuleintoaPRUchassis.Theprocessto

installthefourdifferenttypesofRFModulesisbasicallythesame;however,differencesarenotedandshouldbe

followed.

NOTE: In the following steps, the RF cables and connectors are referred to as MOD N TX0/RX0 and as MOD N

TX1/RX1whereNequalsA,B,C,orD.

NOTE: WheninstallingRFModules,populatetheRFModulesfromhighestfrequencybandtolowestwithinthe

PRU.Likewiseforpoweroutput,populate

fromthebottombaytothetop;higheroutputtoloweroutput.

Thatis,foradeploymentwith210040W,190040W,85020Wand70020WMIMO,installtheRFModules

asfollows:

• 210040WRFModuleinBayA

• 190040WRFModuleinBayB

• 85020WRFModuleinBayC

• 70020WMIMORFModuleinBayD.

SafetyPrecautions

CAUTION! Thisisrestrictedaccessequipmentand onlyqualifiedservicepersonnelshouldserviceand 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! 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! ExteriorsurfacesofthePrismRemoteUnit

maybehot.Usecautionduringservicing.

CAUTION! Servicepersonnelmust confirm that the perimeter gasket and door‐to‐doorgaskets are in place when closing the

Prismdoorsafter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immed iately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.
