Magnum Quad-Series Fiber Switches

Applications
Magnum Quad-Series Mixed-Media 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 Quad-Series Switches enables them to
inter-connect a series of subnets (one subnet per Q-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 : Magnum QS580
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 Magnum
QS580 Quad-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 to connect to more distant LAN centers,
and a configuration with two "combo" 3@RJ-45 + 1@fiber-built-in QPMs is used.
The Magnum QS580 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.
