ï›› Model 4K8 Ethernet 10/100 Switches boost the performanceof Ethernet LANs, with the flexibility of both twisted-pair and a bonusfiber port. The fiber port, an additional or 9
th port, may be configured froma variety of user-selected fiber connector and fiber cable types. The twisted- pair ports are 10/100 auto-negotiating.The “future-proof” fiber port is normally 100Mb speed with fac-tory default setting to operate in full-duplex mode. 100Mb fiber connec- tor types available include multi-mode ST, SC, MV45 and MTRJ, and single- mode 20km or single-mode 40km “long reach” SC. Alternatively, for 10Mb fiber, a multi-mode half-duplex ST-type port option is available. The op- tional fiber port is normally configured and tested with the Magnum 4K8 unit in the factory, but may be configured in the field.In common applications, groups of standard dual-speed 10/100hubs, 10Mb hubs, or 100Mb hubs and switches would form a series of subnets for workgroups or multi-system power users. Each subnet would be served by a separate switched port on a Magnum 4K-Series, and each of these subnets would have full 100Mb or 10Mb bandwidth, operating in either half-or full-duplex mode. Local traffic on one subnet, either 100Mb or 10Mb, is switch-isolated from the other subnets for high overall net- work performance.Magnum 4K8 Switches are easy to install and use. Addresses ofattached nodes are automatically learned and maintained, adapting the switching services to network changes and expansions to provide plug- and-play operation. “Reverse” models with front-mounted ports and LEDs, or with front-mounted LEDs, rear ports and power connection, are avail- able.The Magnum 4K-Series, with store-and-forward switching, filter allfaulty packets to minimize traffic congestion and are non-blocking. Magnum Model 4K8 Switches come in a convenient rack-mountable pack- age; have a rugged metal case and an auto-ranging power supply for op- eration with AC power worldwide.
“Carrier Class” and “Industrial Strength”models with optional DC input power features are also available. The 4K-Series and all Magnum products are made in the USA and are backed by a three-year warranty.
