Connecting UTP Cables
ThefixedRJ45frontpanelportsare10/100/1000Mbpsportsandhaveinternalcrossovers.
Whenconnectingaworkstationtotheseports,useastraight‐throughcable.When
connectingnetworkingdevicestotheseports,suchasabridge,repeater,orrouter,usea
crossovercable.
Toconnecttwistedpairsegmentstothe
switch,refertoFigure 3‐15andproceedas
follows:
1. Ensurethatthedevicetobeconnectedattheotherendofthesegmentis
powered O N.
2. Connectthetwistedpair segmenttothesw itchbyinsertingtheRJ45connectoronthe
twistedpairsegmentintothedesiredRJ45port(forexample,Port8).

Note: All fixed RJ45 front panel ports support Category 5 Unshielded Twisted Pair (UTP)
cabling with an impedance between 85 and 111 ohms. Category 3 cable may be used if
the connection is going to be used only for 10 Mbps.
