FHU-0803TXD
8 Port 10/100Mbps
Dual Speed Ethernet Hub
with Bridge
This quick start guide contains the information necessary to install
and operate the FHU-0803TXD 8 port 10BASE-T/100BASE-TX
dual speed Ethernet Hub.
Introduction
The FHU-0803TXD provides 8 RJ-45 ports for both 10 Mbps or
100 Mbps Ethernet connections, which are detected by auto-
sensing. The dual-speed hub contains two internal repeater buses,
one for 10 Mbps traffic and another for 100 Mbps traffic. Traffic
passing between attached devices that operate at the same speed is
confined within the appropriate repeater bus.
In the FHU-0803TXD, an internal Ethernet switch consisting of a
10 Mbps and a 100 Mbps switching port, is used to link the
repeater buses. Only if traffic has to be passed between a 10 Mbps
and a 100 Mbps device, the data will be forwarded to the other
internal repeater bus if the destination address is not found in the
address table, or broadcast traffic is sent.
