Magnum Quad-Series Fiber Switches
Example 3: Magnum 16-port QS5116
In another situation similar to Example 2 above, a larger central Switch is
needed to provide for a 6-segment 100Mb fiber Fast Ethernet backbone, and switched
copper support for 4 high speed local servers. In addition, the router and two dual-speed
hubs need switched copper ports. The total is 14 ports, 6 fiber and 8 copper.
The mixed-media flexibility of the Magnum Quad-Port Switches provides the
user with more than one configuration in this case. The two ports not immediately used
may be either fiber or copper. If the probable growth of the central Switch is towards
more fiber backbone segments, then two quad-port fiber QPMs are selected to provide 6
required fiber ports and two for spares and/or future backbone expansion. The 8
switched copper ports are handled with two RJ-45 Quad-Port Modules configured into
the Magnum QS5116. Should the number of servers expand, more than one server can
be serviced by a switched QS5116 port by using a small 4-port 100Mbps hub.
If the probable growth of the central Switch is towards more local high speed
servers and users, then one quad-port fiber QPM is selected to provide 4 of the required
fiber ports, and two "combo 3@RJ-45 + 1@fiber" QPMs are configured for the other 2
fiber ports plus 6 of the switched copper ports. Finally, an RJ-45 QPM is configured to
provide for the remaining 2 copper ports plus two for spares and/or future expansion.
Should the need arise to add a built-in-fiber backbone port in the future, the RJ-45 QPM
could be removed and another "3+1 combo" QPM installed in the field. Alternatively, a
100MB Media Converter (such as the Magnum 15E) may be used on a copper port, with
internal jumpers (See Section 3.4) set to support fixed 100MB FDX on the RJ-45 port.
