5.3.2 Ethernet Port Cable Specifications and Pinouts

The 10 Base-T/100 Base-T Fast Ethernet ports support IEEE 802.3 and IEEE 802.3u
specifications for the 10-Mbps and 100-Mbps transmission over Unshielded Twisted-
Pair (UTP) cables. Use Category-3 or Category-5 UTP cable with RJ-45 connectors to
attach the 10/100 Base-T Ethernet LAN A port on the iDirect 3000 series™ Satellite
Router chassis to the customer provided LAN Hub or switch.
NOTE: iDirect supplies one 7-foot Category 5 UTP cable to connect the 3000
series router to the LAN hub or switch. If additional cables or different
lengths are needed, they may be bought commercially.
To determine the type of RJ-45 cable, examine the sequence of the colored wires as
follows:
• Straight through — The colored wires are in the same sequence at both ends of
the cable.
• Crossover — The first (far left) colored wire at one end of the cable is the third
colored wire at the other end of the cable, and the second colored wire at one
end of the cable is the sixth colored wire at the end of the cable.
Table 12 lists the pinouts for the Ethernet ports of the IDU chassis.
