3. VerifythatalinkexistsbycheckingthattheLink/ActivityLEDisON(solidgreenor
blinkinggreen).
4. IftheLink/ActivityLEDisOFF,performthefollowingstepsuntilitison:
a. VerifythatthecablingbeingusedisCategory 5orbetterwithanimpedance
between85and111 ohmswitha
maximumlengthof100meters(328feet).
b. Verifytha tthedeviceattheotherendofthetwistedpairsegmentisonand
properlyconnectedtothesegment.
c. VerifythattheRJ45connectorsonthetwistedpairsegmenthavetheproper
pinoutsandcheckthecableforcontinuity.Typically,acrossover
cableisused
betweenhubdevices.Astraight‐throughcableisusedtoconnectbetween 
switchesorhubdevicesandanenduser(computer).RefertoFigure 3‐16and
Figure 3‐17forfour‐wireRJ45connections.RefertoFigure 3‐18andFigure 3‐19
foreight‐wireRJ45connections.
d. Ensurethatthe
twistedpairconnectionmeetsthedBlossandcablespecifications
outlinedintheCablingGuide.Referto“RelatedDocuments”onpage xvifor
informationonobtainingthisdocument.
5. Ifalinkisnotestablishedorthere isnoPoEpower,contactEnterasys Networks.Refer
to“GettingHelp”onpage 1‐8for
details.
Repeatallstepsaboveuntilallconnectionshavebeenmade.

Note: If the cable is connected to one of the PoE RJ45 front panel ports, solid green or
blinking green also indicates that PoE power is available. If the LED is solid amber or
blinking amber PoE power failed. For more details, refer to Chapter 4.
