Enterasys SecureStack C2 C2G124-48P - Connecting a UTP Cable Segment to RJ45 Port

Connecting to the Network
3-22 Hardware Installation
Toconnecttwistedpairsegmentstotheswitch,refertoFigure 3‐13andproceedas
follows:
1. Ensurethatthedevicetobeconnectedattheotherendofthesegmentis
powered ON.
2. Connectthetwistedpair segmenttotheswitchbyinsertingtheRJ45connectoronthe
twistedpairsegmentintothe
desiredRJ45port(forexample,Port8).

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that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 3‐14and
Figure 3‐15forfour‐wireRJ45connections.RefertoFigure 3‐16andFigure 3‐17
foreight‐wireRJ45connections.

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 okay. If the LED is solid amber or blinking
amber PoE power failed. For more details, refer to Chapter 4.
