1000BASE-T/100BASE-TX/10BASE-T Port
The 1000BASE-T/100BASE-TX/10BASE-T is a 10/100/1000 Mbps auto-negotiation port that supports auto
MDI/MDIX Crossover.
Compliant with IEEE 802.3ab, 1000BASE-T requires Category 5e 100-ohm UTP or STP (recommended) with a
maximum distance of 100 meters (328 feet).
The 1000BASE-T port requires all four pairs of wires to be connected for data transmission. Figure A-1 shows
the connection of twisted pairs used by a 1000BASE-T port.

100BASE-TX/10BASE-T can be interconnected using cables of the preceding specifications. For 10 Mbps, the
100BASE-TX/10BASE-T port can be connected using 100-ohm Category 3, Category 4, and Category 5 cables;
for 100 Mbps, the 100BASE-TX/10BASE-T port can be connected using 100-ohm Category 5 cables with a
maximum connection distance of 100 meters. The following table shows 100BASE-TX/10BASE-T pin
assignments.

Figure A-3 shows feasible connections of straight-through and crossover twisted-pair cables for
100BASE-TX/10BASE-T.
