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 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.
