Figure 33 1000BASE-T (1000 GT) Ethernet interface card
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 interface card..
