Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
2.5 Applications
The Magnum Dual-speed Hub Plus is designed to provide dual speed (10/100Mbps)
connectivity. Pictured below, a Magnum DS50 Dual-speed Hubs serves a small office with
mixed speed requirements. Some
users operate at 100Mbps, and some
users and utility devices (such as
print servers) run at 10Mbps. All
share the same hub, and
communicate to each other via the
bridge logic inside. Any node can change speed at any time without affecting network
operation or impacting other users. It is simple to install and use, making shared Fast Ethernet
networks practical for connecting high performance user groups in a variety of ways.
Since 10/100 NICs are widely available at low cost, 100BASE-TX Fast Ethernet has
become desirable for many performance-oriented users. They usually want their new 100Mb
network segment to be interoperable with existing 10Mb networks, and to be a separate
collision domain in order to maximize performance of both segments. This is where bridged-
dual-speed provides flexibility by enabling the newly installed 100Mb ports to communicate
smoothly with existing 10Mb nodes and hubs.
For this example, DS60C Port 6 may be used as a 10Mb port to an existing 10Mb hub
while Ports 1-5 are a new separate collision domain of shared 10/100 ports.
