Magnum Model 4K24F and 4K24C Switches boost the performance of large Ethernet LANs, with the flexibility of both twisted-pair and fiber switched ports. Fiber ports may number zero, one or two, and a variety of user-selected fiber connector types may be configured. The Magnum 4K-Series provide the switching speed and the reliability to smoothly support multiple workgroups, each with its own switched 100Mb or 10Mb domain, for increased network performance and with “future-proof” fiber ports optionally built in. The Magnum 24-port 4K24F Switches offer application flexibility with a series of optional fiber connector types. All applicable fiber port types (100Mb FX-ST, SC, MTRJ) and fiber cable modes (multi-mode and single-mode) are configurable using a family of 1- or 2-port modules. The twenty-two twistedpair ports are 10/100 auto-negotiating. The 1 or 2 fiber ports, when present, render the corresponding two copper ports inoperative. In a common application, the 4K24 would be at the center of a departmental LAN, with high performance users and servers connected to most ports. In addition, groups of 10 Mb hubs, or 100Mb hubs and switches would form a series of subnets for other users. Local traffic on one subnet or port, either 100Mb or 10Mb, is switch-isolated from the other subnets for high overall network performance. Designed for use in organizations with multiple workgroups, remote offices and network traffic centers, the Magnum 4K24 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. LEDs provide status information on each port. Models with front-mounted ports and LEDs, or with front-mounted LEDs, rear ports and power connection, are available. The Magnum 4K24 Switches are non-blocking on all 24-ports, and include large 1MB packet buffers for advanced performance, even with unbalanced loads. The dynamic 2K-node address table allows the 24-port Magnum 4K24F and 4K24C models to support large networks. Magnum 4K24 Switches provide high port density in a rack-mountable package; have a rugged metal case and an auto-ranging power supply for operation with standard AC power worldwide. Models with optional DC input power are available. The 4K-Series and all other Magnum products are designed and manufactured in the USA and backed by a three-year warranty.


PERFORMANCE: RJ-45 Ports: 100 or 10Mb / second speed, full- or half-duplex mode, per port, individually determined. 10/100 auto-negotiating, FDX/HDX (internal jumper can select 100 only) Fiber Ports (m.-mode and sgl.-mode): 100Mb speed per port based on the fiber connector part. FDX or HDX, default is FDX mode. (Internal jumper can select FDX-only) All Ports: Processing type: Store and Forward with IEEE 802.3x full-duplex flow control, non-blocking System aggregate forward and filter rate: 3.6M pps, (All ports 100 Mb full speed) Address table: 2K nodes, self-learning, with address aging Packet buffers: 1 MB dynamic Latency: Less than 5µs (not including packet time)(TX -TX, TX – FX, FX – FX) PDV: 50BT
