Appendix A Technical specifications 83Nortel VPN Router Installation — VPN Router 27001000BASE-T (1000 GT) Ethernet interface cardThe 1000BASE-T (1000 GT) Ethernet card replaces the 10/100BASE-TXEthernet card (see the previous section). This card provides 10/100/1000 Mbit/sEthernet services and supports autonegotiation. The card supports the IEEE802.3ab standard and provides RJ-45/CAT 5 interconnection. It can operate ineither full or half duplex mode at 10/100 Mbit/s, and in full duplex mode at 1Gbit/s. At 1 Gbit/s, autonegotiation must be used.The VPN Router 2600 only supports 10/100 Mbit/s operation for the1000BASE-T (1000 GT) Ethernet card. To ensure reliable speed/duplex operationon these platforms, Nortel recommends that both the interface and the attacheddevices are hard-coded to the appropriate matching 10/100 speed and duplexsettings.The 1000BASE-T (1000 GT) Ethernet card supports 10/100/1000 Mbit/soperation in the VPN Router 2700/2750.For the 1000BASE-T (1000 GT) Ethernet interface card to be recognized by thesystem, 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 versionsThe 1000 GT card does not replace the high-performance 1000BASE-T 1000 MTcard (see the following section).The following figure shows the 1000BASE-T (1000 GT) Ethernet interfacefull-height card for VPN Router.Note: The 1000BASE-T (1000 GT) Ethernet interface card can onlyoperate at 10/100 Mbit/s on the VPN Router 2600.
