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.
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
startup. To change the speed, turn off the unit, connect to the desired LAN, and
restart the unit.
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.
