System ports
The Contivity 1700 system board provides the following built-in interfaces:
• 10/100BASE Ethernet LAN port
• Serial port
This section provides information about the 10/100BASE Ethernet LAN port and
the serial port on the system board.
10/100BASE Ethernet LAN port
The system board provides one 10/100BASE Ethernet LAN interface on the rear
of the chassis. This LAN interface, which accommodates an RJ-45 straight-
through cable, is generally used for Web management. Depending on whether you
will use the interface for 10BASE-T or 100BASE-TX operation, select cables for
the interface as follows:
• 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.
Figure 25 shows the 10/100BASE connector and its pinouts.
