Example 2 : Magnum 8-port QS5108

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

The Magnum QS5108 equipped with one Fiber and one RJ-45 quad-port modules provides an economical solution, configured with 8 switched ports (four 100Mbps fiber and four 10/100 RJ-45) in a rack-mount box. No Media Converters are needed. The Fiber QPM can be selected to provide any 100Mbps fiber media connector type desired. QPMs with multi-mode or single-mode fiber types are available.

This requirement for connecting local devices over twisted pair cabling is handled by the Magnum QS5108 using a 4-port RJ-45 Quad-Port Module. The QPM provides a switched port for two local high speed servers, another for the router, another for the users connecting into a 16-port dual-speed hub such as the Magnum DS8016.

Since 100Mb fiber Ethernet has severe distance limitations at half-duplex, it is necessary in high speed backbones to operate fiber links in the full-duplex mode. Many low-end switches that only have RJ-45 N-way 10/100Mb ports would need to have a media converter on each fiber line. But most media converters do not support auto- negotiation and would not enable the fiber backbone lines to operate full-duplex. But the Magnum QS5108 . . . with built-in switched fiber ports at 100Mb speed, with full-duplex mode as a default setting on fiber ports, and with some RJ-45 N-way 10/100Mb ports as well. . . handles this application readily.
