Select cables for this card as follows. Keep in mind that this card is

auto-negotiating and uses the highest possible data rate:

• 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 pinouts for the 1000BASE-T (1000 GT) Ethernet
