10/100BASE-TX Ethernet interface card

The 10/100BASE-TX Ethernet interface card has a single RJ-45 connector that provides the signals needed to interface to 10BASE-T and 100BASE-TX Ethernet equipment. Figure 17 shows the 10/100BASE-TX Ethernet interface card.

For information about the cables that you can connect to this interface and the cable pinouts, see “10/100BASE-TX Ethernet LAN ports” on page 42.

1000BASE-T (1000 GT) Ethernet interface card

The 1000BASE-T (1000 GT) Ethernet card replaces the 10/100BASE-TX Ethernet card (see the previous section). This card provides 10/100/1000 Mbit/s Ethernet services and supports autonegotiation. The card supports the IEEE 802.3ab standard and provides RJ-45/CAT 5 interconnection. It can operate in either full or half duplex mode at 10/100 Mbit/s, and in full duplex mode at 1 Gbit/s. At 1 Gbit/s, autonegotiation must be used.

Note: The 1000BASE-T (1000 GT) Ethernet interface card can only operate at 10/100 Mbit/s on the VPN Router 1100.

The VPN Router 1100 only supports 10/100 Mbit/s operation for the 1000BASE-T (1000 GT) Ethernet card. To ensure reliable speed/duplex operation on these platforms, Nortel recommends that both the interface and the attached devices are hard-coded to the appropriate matching 10/100 speed and duplex settings.

For the 1000BASE-T (1000 GT) Ethernet interface card to be recognized by the system, the minimum required VPN Router operating software is:
