LAN Interface Connections
The LAN interface is available for the Contivity Extranet Switch 1500 and 1510.
There is at least one LAN interface connection, which provides a connection to
the Web for 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.
100 meters is the maximum recommended cable segment length 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.
LAN Speed Selection
The Switch automatically determines the speed of the LAN connection during
power-up. To change the speed, simply power down the unit, connect to the
desired LAN, and power the unit back up.
Connector Pinouts
The LAN connectors on the Switch are RJ-45 straight-through. The following
illustration shows the Switch connector's 10/100BASE-TX pinouts.
