Triple-Speed Functionality, and Switching
The LBH2001A Series Converter Switches provide three switched ports. The
architecture supports a triple 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 LBH2001A 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.
LBH2001A 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 are user options for port #2, to configure it FF/AN. The internal
functions of both are described below.
