The port on the 1000BASE-T Ethernet interface card accommodates an RJ-45 straight-through cable. Select cables for this port as follows:

•For 1000BASE-T operation, use category 5 four-pair Ethernet wiring. The cable must comply with the TIA 568 wiring specification. Nortel recommends a maximum length of 100 meters for the cable segment.

•For 100BASE-TX operation, use category 5 twisted-pair wiring: one pair each for transmit and receive operations. The cable must comply with the

EIA 568 wiring specification. Nortel recommends a maximum length of 100 meters for the cable segment.

•For 10BASE-T operation, use category 3, 4, or 5 twisted-pair wiring.

The following table provides the 1000BASE-T (1000 MT) Ethernet port pinouts.
