Nortel VPN Router Installation — VPN Router 1010/1050/1100
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.
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:
• 5.05.330
Note: The 1000BASE-T (1000 GT) Ethernet interface card can only
operate at 10/100 Mbit/s on the VPN Router 1100.
