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.
The following figure 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 70.
1000BASE-T (1000 GT) Ethernet interface card
The 1000BASE-T (1000 GT) Ethernet card replaces the 10/100BASE-TX Ethernet card (see the preceding section). This card provides 10/100/1000 Mb/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 Mb/s, and in full-duplex mode at 1 Gb/ s. At 1 Gb/s, autonegotiation must be used.
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).
