1000BASE-T/100BASE-TX/10BASE-T
The 1000BASE-T/100BASE-TX/10BASE-T is a 10/100/1000 Mbps auto-negotiation port that supports auto
MDI/MDIX.
Compliant with IEEE 802.3ab, 1000BASE-T requires Category 5e 100-ohm UTP or STP (STP is recommended)
with a maximum distance of 100 meters (328 feet).
1000BASE-T requires all four pairs of wires be connected for data transmission, as shown in Figure 7-1.

1000BASE-T Connection
10BASE-T uses Category 3, 4, 5 100-ohm UTP/STP and 1000BASE-T uses Category 5 100-ohm UTP/STP for
connections. Both support a maximum length of 100 meters. Figure A-2 shows100BASE-TX/10BASE-T pin
assignments.
