1000BASE-T (1000 MT) Ethernet interface card
Use the 1000BASE-T (1000 MT) Ethernet interface card to connect to Gigabit
Ethernet interfaces on other devices in your network, as well as to provide
increased throughput. This interface card has a single RJ-45 connector.
Figure 34 shows the 1000BASE-T Ethernet interface card.

1000BASE-T (1000 MT) Ethernet interface card
The port on the 1000BASE-T (1000 MT) 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 a 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 a cable segment.
• For 10BASE-T operation, use Category 3, 4, or 5 twisted-pair wiring.
Table 23 provides the 1000BASE-T (1000 MT) Ethernet port pinouts.
