Example 2. Magnum DS80C
The Magnum DS80C fits very well with small business seeing a growth in users
volume and are forced to scale network quickly and cost effectively. Due to its 1SW and 2SW
Full duplex switching capability, the DS80C provides a very economical high Bandwidth
solution at copper port. The Dual-Speed functions supports a mixed environment of 10Mbps and
100Mbps users and the switching full duplex capability on 1SW and 2SW provides a high
bandwidth uplink solution for expansion. The “FF-A” manual switch options for port 2SW allow
this Hub to connect at Full duplex to any non-Auto-negotiating Switch using the “FF” mode.

Figure 2.6.1: Two DS80C connects together to provide 10Mbps and100Mbps network with
Fast Ethernet backbone.
In this example, two of the Magnum DS80C Personal Hub cascaded together to serve a small
office with multi-server, print server, internet access and mixed-speed requirements. The users
operate at 100Mb as well as at 10Mb 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. Any attached node can change speed at any time without affecting network
operation or impacting other users. The two DS80C cascaded together solve the requirement
economically with reliability.
The Dual-Speed characteristic allows the DS80C to support the 10Mbps and 100Mbps
traffic and always operates at the higher speed. The switching capability at 1SW and 2SW
boosted the personal hub with its own switched 100Mbps or 10Mbps domain and provide a Fast
ethernet backbone for expanding the network.
