Magnum DS80F & DS80C Dual-speed Stackable Hubs Installation and User Guide (12/01)

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.
