The VMIVME-7805/VME-7805RC support Ethernet LANs with two Intel Ethernet
controllers (one 82540EM GbE controller for the VMIVME-7805 or one 82541PI for
the VME-7805RC and the other 10Base-T, 100Base-TX). GbE options are
supported via the front panel RJ45 connectors; 10Base-T and 100Base-TX is
supported via a second RJ45 connector.
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.
The VMIVME-7805/VME-7805RC also support the 100Base-TX Ethernet.
A network based on a 100Base-TX standard uses unshielded twisted-pair cables
and a RJ45 connector. 100Base-TX has a maximum length of 100 meters.
The VMIVME-7805/VME-7805RC support GbE offering speeds of 1000Mb/s. It is
fully compatible with existing Ethernets, as it uses the same CSMA/CD and MAC
protocols. 1000BaseT has a maximum length of 3000 meters using Single-mode
Fiber-Optic cables.
The VMIVME-7805/VME-7805RC support booting on the 10/100 Mbit Ethernet
port using a ROM Ethernet BIOS. Refer to Appendix D: Argon BIOS, page 76 for
more information on remote Ethernet booting.
