Magnum DS50 / DS60s Dual Speed Hubs Installation and User Guide (06/02)
In this example, a Magnum DS60F Dual-speed Hub serves in an Industrial place with servers
and mixed-speed requirements, such as collecting data or downloading data from servers or
other sources. Some users operate at 100Mbps, and some users and utility devices (such as print
servers) run at 10Mbps. High performance users need a high bandwidth backbone for access to
a central LAN and central file servers. A Magnum DS60F Dual-speed Hub with 24VDC or -
48VDC power supply serves this requirement economically. The five dual-speed port
capability and a 100Mbps Fiber port makes the required setup simple. Any attached node can
change speed at any time without affecting network operation or impacting other users.
Existing 10Mbps hub or switch users can easily be cascaded into any copper ports of
the DS60F. This allows a simple plug-and-play addition of 100Mbps port to an existing
10Mbps network without having to change it. Nodes that are capable of 100Mbps speed can be
moved to a DS60F port, and will automatically operate at the higher speed.
The 100Mb Full-duplex (default) fiber port on the DS60F can be used for
accommodating high performance data transfers, and provides fiber connectivity built-in rather
than needing an auxiliary media converter unit. The 100Mbps traffic does not use the
bandwidth of the 10Mbps domain, so overall performance of the network is sustained at the
highest possible level.
