Black Box LE14XXA-Series

Modular Switches offer high performance and flexibility

and are easily used in a variety of applications including client/server computing, performance upgrades of departmental networks, and collapsed backbone applications. The Dual-Speed characteristic of the LE14XXA-Series Switches enables them to inter-connect a series of subnet (one subnet per LE14XXA-Series Switch) in a LAN traffic center. The subnet connections may be via either fiber or twisted pair cabling, and may be 100Mbps or 10 Mbps speed and full-or half-duplex mode.

The mixed-media capability is ideal for upgrading existing Ethernet LAN networks, where existing cabling must be accommodated. The fiber-built-in media capability is ideal for integrating future-proof fiber cabling into the LAN structure.

Example 1 : LE1401A

In a typical 10 Mb network performance upgrade, some existing cascaded 10 Mbps hubs connect a group of users who share one 10 Mb traffic domain. The LE1401A 4port Series Switch provides eight 10/100Mb traffic domains for increased performance. It can segment 10 Mbps and 100Mbps units, hubs and servers, in the existing network into multiple domains, providing greatly increased bandwidth. In this case, two 100Mb fiber connections are required t connect to more distant LAN centers, and a configuration with two “combo” 3@RJ-45 + 1@fiber-built-in 4PMs is used.

The LE1401A provides complete network connectivity so that all 10 Mb and 100Mb nodes operate in a unified manner, functioning as one plug-and-play switched network facility. It filters and forwards packets from one segment to another, containing the local traffic and allowing only the packets which need to be forwarded to go outside to the appropriate other segments. This is ideal for a central departmental switch in a high-performance LAN center. Figure 2.4 illustrates this example.
