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.
Figure 22 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).
