Magnum DS80F & DS80C Dual-speed Stackable Hubs

Installation and User Guide (12/01)

2.6Applications

The DS80F & DS80C are designed to bring future-proof fiber connectivity and highly used copper connectivity to small user groups in offices, classrooms and labs.

Example 1. Magnum DS80F In this example, a Magnum DS80F Personal Hub serves a small office with multi-server and mixed-speed requirements. 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 DS80F Personal Hub serves this requirement economically. The two 1SW and 2SW full-duplex switched ports capability makes the required setup simple. Any attached node can change speed at any time without affecting network operation or impacting other users.

10 Mbps Workgroups

Figure 2.6.1: A DS80F connects combinations of 10Mbps and100Mbps network devices and

provides a Fast Ethernet fiber backbone for access to the central LAN.

Where there is existing 10Mbps hubs and users, they can easily be cascaded into any port of the DS80F. This allows a simple plug-and-play addition of 100Mbps ports to an existing 10Mbps network without having to change it. Nodes that are capable of 100Mbps speed can be moved to a DS80F dual-speed port, and will automatically operate at the higher speed.

The 1SW full duplex 100Mbps switched port can support a local server for Fast Ethernet users. The 100Mb fiber port on the DS80F 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.
