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.
The following figure shows the 1000BASE-T (1000 MT) Ethernet interface card.
Figure 24 1000BASE-T (1000 MT) Ethernet interface card
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.
