4 FollowtheserulesfortheCATVcableswhenconnectingtheIFEUtotheMRAU:

• TheFWDandREVcablesshouldbeclosetothesamelength.

• TheFWDandREVcablesshouldbethesamecabletype(bothRG6orbothRG11).

• ApairofCATVcablesconnectseachMRAUtotheIFEU.TheIFEUREVModuleIFINport

andtheIFEUFWDModuleIFOUTportmustmatch.Forexample,ifIFEUREVModuleIF

INPort3isused,useIFEUFWDModuleIFOUTPort3.

• Referto“AppendixB:75‐OhmCATVCable”onpage24forinformationonmaximumRG‐6

orRG‐11CATVcablelengths.

5 TestthecableterminationforeachCATVcablebeforeinstallingit.

6 ConnectFconnectorCATVcablesontheIFEUandMRAU,intheordergivenbelow.

IftheLEDsdonotperformasdescribedinthisprocedure,referto“MRAULEDs”onpage8.

a ConnectaCATVcablefromoneoftheIFEUFWDModuleIFOUTconnectors(1‐8)tothe

MRAUFWDIFINconnector.

b ConfirmthattheMRAUFWDIFINLEDisyellow,whichindicatesacorrectphysical

connection.

c ConnectaCATVcablefromtheIFEUREVModuleIFINconnector(1‐8)totheMRAUREV

IFOUTconnector,makingsurethatyoupairtheportusedtothesameportnumber

selectedinStep6a.

Iftheconnectioniscorrect,theMRAUpowersupandtheMRAUFWDIFINLEDturns

green.
