LAN interface connections
The Contivity has two LANs built in. LAN0 is the Private LAN and is also the
LAN to use for Web management. LAN1 defaults to a Public LAN. The Contivity
software refers to the LAN1 port as Slot 1, interface 1.
At least one LAN interface connection is for Web management.
100BASE-TX connections require Category 5, twisted-pair wire. The
100BASE-TX specification supports 100 Mb/s transmission over two pairs
of Category 5 twisted-pair Ethernet wiring; one pair each for transmit and
receive operations.
The maximum recommended cable segment length is 100 meters between a
100BASE-TX repeater and a workstation (due to signal timing requirements).
This wiring scheme complies with the EIA 568 wiring standard.

10BASE-T connections can use Category 3, 4, or 5 twisted-pair wiring. The
LAN connectors on the rear of the Contivity are RJ-45 straight through.
