Media Converter Switches Installation and User Guide

4.0 OPERATION
4.1 Dual-Speed Functionality, and Switching
The LBH100A and LBH110A Series Media Converter Switches provide four
switched ports (three ports in the front and one on the rear). The architecture supports a
dual speed switching environment, with standard auto-negotiation capability.
The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and
speed, and auto-cross for plug polarity. (See Section 2.2). When the connected device is 10
Mbps, the LBH100s obeys all the rules of 10 Mbps Ethernet configurations. The 10 Mbps
users can “communicate” with 100Mbps users as well as other 10 Mbps users through the
switch. Similarly, the 100Mbps traffic obeys the rules of 100Mbps Ethernet, and can
communicate with 10 Mb and 100Mb users.
LBH100A and LBH110A Series units are plug-and-play devices. There is no
software configuring to be done at installation or for maintenance. The only hardware
configuration settings is user options for port #2, to configure it FF/AN. The internal
functions of both are described below.
