3. Plugtheotherendofthecableintotheappropriateportontheotherdevice.Some
cablesmaybeterminatedattheotherendwithtwoseparateconnectors,oneforeach
fiber‐opticstrand.Inthiscase,ensurethatthetransmitfiber‐opticstrandisconnected
tothereceiveport
andthereceivefiber‐opticstrandtothe transmitport.
4. VerifythatalinkexistsbycheckingthattheportLink/ActivityLEDison(blinking
greenorsolidgreen).IftheLink/ActivityLEDisoff,performthefollowingstepsuntil
itison:
a. Verifythatthedeviceattheotherendof
thesegmentisONandconnectedtothe
segment.
b. Ifthereareseparatefiber‐opticconnectionsontheotherdevice,checkthe
crossoverofthecables.Swapthecableconnectionsifnecessary.
c. Checkthat thefiber‐opticconnectionmeetsthedBlossandcablespecifications
outlinedintheCablingGuidefor
multimodecabling.Toobtainthisdocument,
referto“RelatedDocuments”onpage xvi.
Ifalinkhasnotbeenestablished,refertoChapter 4forLEDtroubleshootingdetails.If
aproblempersists,referto“GettingHelp”onpage 1‐7fordetailsoncontacting

5. Repeatsteps1through4,
above,untilallconnectionshavebeenmade.
