LAN interface connections

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.
