4.7.2 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 Evolution X5 Satellite Router chassis to the
customer provided LAN Hub or switch.
Note: iDirect supplies one 7-foot Category 5 UTP cable to connect the Evolution X5
Satellite 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 and they are shown in
Figure 16 on page 31.
