Nortel VPN Router Installation — VPN Router 2700

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 2600 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.

The 1000BASE-T (1000 GT) Ethernet card supports 10/100/1000 Mbit/s

operation in the VPN Router 2700/2750.

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

• 6.05.140 and all subsequent versions

•7.00.062

• 7.05.100 and all subsequent versions (FIPS branch)

• 7.05.300 and all subsequent versions

The 1000 GT card does not replace the high-performance 1000BASE-T 1000 MT

card (see the following section).

The following figure shows the 1000BASE-T (1000 GT) Ethernet interface

full-height card for VPN Router.

Note: The 1000BASE-T (1000 GT) Ethernet interface card can only

operate at 10/100 Mbit/s on the VPN Router 2600.
