xample 2 : 8-port LE1408A

In another application, a Switch is needed to provide a Fast Ethernet backbone. The ckbone consists of four high-speed LAN segments, each operating over 100MB full-duplex ber lines. In addition to interconnecting the fiber backbone segments in the network center, the witch needs to provide high-speed switched support for two central servers, for a 100MB nnection to a router, and for a dual-speed hub serving a local workgroup of over a dozen users, inters, etc.

The LE1408A equipped with one Fiber and one RJ-45 4-port modules provides an onomical solution, configured with 8 switched ports (four 100Mbps fiber and four 10/100 RJ- ) in a rack-mount box. No Media Converters are needed. The Fiber 4PM can be selected to ovide any 100Mbps fiber media connector type desired. 4PMs with multi-mode or single- ode fiber types are available.

This requirement for connecting local devices over twisted pair cabling is handled by e LE1408A using a RJ-45 4-Port Module. The 4PM provides a switched port for two local gh speed servers, another for the router, another for the users connecting into a 16-port dual- eed hub such as the LE1408A.

Since 100Mb fiber Ethernet has severe distance limitations at half-duplex, it is cessary in high speed backbones to operate fiber links in the full-duplex mode. Many low-end witches that only have RJ-45 N-way 10/100Mb ports would need to have a media converter on ch fiber line. But most media converters do not support auto-negotiation and would not enable e fiber backbone lines to operate full-duplex. But the LE1408A . . . with built -in switched fiber rts at 100Mb speed, with full-duplex mode as a default setting on fiber ports, and with some J-45 N-way 10/100Mb ports as well. . . handles this application readily.
