2.7 Ethernet Controllers

The V7865 supports Ethernet LANs with two Intel Ethernet controllers (82571
Dual GbE controller). 10Base-T, 100Base-TX and GbE options are supported via
two front panel RJ45 connectors.

2.7.1 10Base-T

A network based on the 10Base-T standard uses unshielded twisted-pair cables,
providing an economical solution to networking by allowing the use of existing
telephone wiring and connectors. The RJ45 connector is used with the 10Base-T
standard. 10Base-T has a maximum length of 100 meters.

2.7.2 100Base-TX

The V7865 also supports the 100Base-TX Ethernet. A network based on a
100Base-TX standard uses unshielded twisted-pair cables and an RJ45 connector.
100Base-TX has a maximum length of 100 meters.
2.7.3 1000Base-T
The V7865 supports GbE offering speeds of 1000 Mbit/s. It is fully compatible
with existing Ethernets, as it uses the same CSMA/CD and MAC protocols.
1000Base-T has a maximum length of 3000 meters using Single-mode Fiber-Optic
cables.

2.7.4 Boot ROM BIOS

The V7865 supports booting on the front panel GbE ports using a ROM Ethernet
BIOS. Refer to Appendix C: Remote Booting for more information on remote
Ethernet booting.
