Magnum Model 4K8 Ethernet 10/100 Switches boost the
performance of Ethernet LANs, with the flexibility of both twisted-pair and a
bonus fiber port. The fiber port, an additional or 9th port, may be configured
from a 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 factory
default setting to operate in full-duplex mode. 100Mb fiber connector 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 optional 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 10/100 hubs, 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 network performance.
Magnum 4K8 Switches are easy to install and use. Addresses of attached 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 available. The Magnum 4K-Series, with store-and-forward switching, filter all faulty packets to minimize traffic congestion and are non-blocking.
Magnum Model 4K8 Switches come in a convenient rack-mountable package; have a rugged metal case and an auto-ranging power supply for operation with AC power worldwide. “Carrier Class” and “Industrial Strength” models with optional DC input power features are also available. The 4KSeries and all Magnum products are made in the USA and are backed by a three-year warranty.
Ports 1-8: 100 or 10Mb, full- or half-duplex mode per port, individually determined. 10/100 auto-negotiating.
