4 FollowtheserulesfortheCATVcableswhenconnectingtheIFEUtotheMRAU:
• T
heFWDandREVcablesshouldbeclosetothesamelength.
• T
heFWDandREVcablesshouldbethesamecabletype(bothRG6orbothRG11).
• Apairo
f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19forinformationonmaximumRG‐6
orRG‐11CATVcablelengths.

IftheLEDsdonotperformasdescribedin
thisprocedure,referto“MRAULEDs”onpage7.

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