Magnum 4K16 Switches offer high performance 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 4K16 Switches enables them to inter-connect a series of subnets (one 

subnet per 4K-Series Switch) in a LAN traffic center. The subnet connections may be via 

either optional fiber or twisted pair cabling, and may be 100Mbps or 10 Mbps speed and 

full-or half-duplex mode. The 16 ports switching capability of 4K16 allow to support a 

larger network with multiple workgroups.  

 

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. 

Example1:  In general application, a Switch is needed to provide a Fast Ethernet 

departmental backbone.  A switch is needed to provide a Fast Ethernet departmental 

LAN center requiring sixteen high speed LAN segments, at least 14 operating over 

100Mbps full-duplex RJ-45 lines.  In addition to interconnecting the two fiber backbone 

segments in the network center, the Switch needs to provide high-speed switched support 

for two central servers, for a connection to a router, and a combination of 10 and 

100Mbps ports for a local workgroup of over a dozen users, printers, etc. 

The Magnum 4K16 equipped with two optional Fiber port and 16 RJ-45 port 

modules provides an economical solution, configured with 16 switched ports ( 10/100 

RJ-45) in a rack-mount box.  The two Fiber FKM can be selected to provide any 

100Mbps fiber media connector type desired.  

 

This requirement for connecting local devices over twisted pair cabling is 

handled by the Magnum 4K16.With the optional Fiber-Port Module, a 2-port FKM, there 

is  a switched port for distance and  high bandwidth throughput to the remote department 

consisting of 4 users. 

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
