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.
