ThissectionprovidestheproceduresforconnectingCategory5unshieldedtwistedpair(UTP)
segmentsorSFPandSFP+pluggabletransceiversfromthenetworkorotherdevicestotheSSA.
Connecting Category 5 UTP Ethernet Cables to the RJ45 Ports
ThefixedRJ45frontpanelconnectionsoftheSSA‐T4068‐0252andSSA‐T1068‐0652are10/100/1000
Mbpsports.Theyhaveinternalcrossoversandsupportautomatic‐polaritysensingwhich
eliminatestheneedforacrossovercable,regardlessofwhethertheconnectionistoanother
networkdeviceoraworkstation.
1. Ensurethat
thefar‐enddeviceconnectedtotheotherendofthesegmentispoweredON.
2. Connectthefar‐enddevice’stwistedpairsegmentintotheappropriateSSARJ45port
connector.
3. VerifythatalinkexistsbycheckingthattheportRX(Receive)LEDisON(flashingamber,
blinkinggreen,orsolidgreen).

IftheRXLEDisOFFandtheTX(Transmit)LEDisnotblinkingamber,performthefollowing
stepsuntilitison:
a. VerifythatcablingisCategory5UTPwithanimpedancebetween85and111 ohms.Ifthe
portistooperateat100 Mbpsor1000Mbps,youmustuseCategory 5
cabling.
b. Ve rify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.
Ifalinkisnotestablished,refertoChapter 3,
Troubleshooting,fordetails.
4. Repeatsteps1–3,untilallconnectionshavebeenmade.
Note: If the SSA is being installed in a network using Link Aggregation, there are rules concerning
the network cable and port configurations that must be followed for Link Aggregation to operate
properly. Before connecting the cables, refer to the Enterasys S-Series Configuration Guide for the
configuration information. For details on how to obtain manuals, refer to “Related Documents” on
page xvi.
Note: All RJ45 front panel ports on the SSA-T4068-0252andSSA-T1068-0652support Category 5
Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. You can use
Category 3 cable only for 10 Mbps connections.
