2.5 Ethernet Controller
36 VMICPCI-7055/CPCI-7055RC Hardware Reference Manual
The network capability is provided by the Marvell MV64460 controller, with three
independent channels. The VMICPCI-7055/CPCI-7055RC support 10BaseT,
100BaseTX and 1000BaseT Ethernet.
2.5.1 10BaseT
A network based on the 10BaseT 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 10BaseT
standard. 10BaseT has a maximum length of 100 meters.
2.5.2 100BaseTX
The VMICPCI-7055/CPCI-7055RC also support the 100BaseTX Ethernet. A
network based on a 100BaseTX standard uses unshielded twisted-pair cables and
an RJ45 connector. 100BaseTX has a maximum length of 100 meters.
2.5.3 1000BaseT
The VMICPCI-7055/CPCI-7055RC support 1000BaseT using the Marvell MV64460
controller. The interface uses shielded cables with four pairs of conductors, along
with an RJ45 connector on the front panel and two channels routed to the
CompactPCI J3 connector for use with the VMIACC-7055/ACC-7055RC RTMs.
The Gigabit Ethernet is also available with the optional PICMG 2.16 routed to the
CompactPCI backplane.
NOTE
Ethernet activity is monitored on the front panel LEDs by a blinking yellow LED. The yellow LED will be on
continuously when the Ethernet port is linked but with no activity.
NOTE
If the PICMG 2.16 option is available on the VMICPCI-7055/CPCI-7055RC, then the Gigabit Ethernet can
not be used with the VMIACC-7055/ACC-7055RC RTMs.
