Connecting UTP Cables
ThefixedRJ4 5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.

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.
