Magnum 3000 Stackable Hubs Installation and User Guide (07/06)

2.7Applications

The Magnum 3000 Stackable Hubs provide a flexible and cost-effective

solution to a variety of Ethernet networking applications. The combination of Stackable Hubs and Stackable Mixed-Media Concentrators with optional SNMP is unique and powerful.

Figure 2.7, taken from an installation in a small educational institution building, illustrates some of the capabilities. The task was to economically network two workgroups of PCs in Wing A and Wing C, and to consolidate them with an existing group of UNIX workstation users in Wing B.

Here, a Magnum 3024 hub for 18 UNIX users in Wing B is being used to add to and to support a ThinNet (10BASE2) segment. The BNC port is implemented via an RPM-BNC in the rear bonus port. This hub is connected to a stack of two Magnum 3024's and one Magnum 3012 for 56 PC users in Wing A. A second segment of Fiber (10BASE-FL) cable provides a link from the Wing A Magnum stack to an additional 22 users in Wing C. The optional future SNMP-based network manager can be connected to any unit of the Magnum stack in Wing A. (A single SNMP agent may be added to the Wing A stack as a future enhancement, for use with network management software. Also note that BPMs in the bonus ports at Wings B and C can bridge-isolate this network into 3 segments, each with essentially full bandwidth for high performance).

Because the high quality Magnum 3000s adhere to industry standards for physical layer connectivity and for network management, they are popular choices for small-to-medium-sized Ethernet networks where reliability and economy are required.
