The 4K16 Switches boost the performance of medium-sized Ethernet LANs, with the flexibility of both twisted-pair and fibre switched ports. fibre ports may number zero, one or two, and a variety of user selected fibre connector types may be configured. The 4K-Series provides the switching speed and the reliability to smoothly support multiple workgroups, each with its own switched 100Mb or 10Mb domain, for increased network performance.

The 4K16 Switch offers application flexibility with a series of optional fibre connector types. Users may choose a fibre port type (100Mb FX-ST, SC, MTRJ) and fibre cable mode (multi-mode and single-mode) which are configurable using a family of 1- or 2-port modules. The twisted-pair ports are 10/100 auto-negotiating.

In a common application, 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. A separate switched port on a 4K-Series Switch would serve each subnet, 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

. 4K16 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. “Reverse” models with front-mounted ports and LEDs, or with front-mounted LEDs, rear ports and power connections, are also available.

The 4K16 Switches are non-blocking on all 16-ports, and include large 2MB packet buffers for advanced performance, even with unbalanced loads. The dynamic 2K-node address table allows the 16-port 4K16 to support medium-sized networks. The entire 4KSeries, with store-and-forward switching, filters all faulty packets to minimize traffic congestion. Model 4K16 Switches are provided in a rack-mountable package and have a rugged metal case and an auto-ranging power supply for operation with standard AC power worldwide. “Carrier Class” and “Industrial Strength” models with optional DC input power features are also available. The 4K-Series and all other products are designed and manufactured in the USA and backed by a three-year warranty.
