Description
Magnum™ 15E Media Converters offer a compact, cost-effective 
way to incorporate fiber media into a Category 5 TX-based Fast Ethernet network. 
They cost significantly less than full repeaters and do not use as much of the 
Fast Ethernet cable and repeater distance budget. 
Each Magnum 15E transparently supports both half- and fullduplex 
operation, and can be used in any Fast Ethernet network 
application. 
The up-link switch on the Magnum 15Es TX port allows the 
units to gracefully fit into any installation, without crossover cables. 
When the Magnum 15E is used to convert a 100Mb/s RJ-45 shared 
or switched hub port to fiber media, the up-link switch is set to the 
“X” position. When the Magnum 15E is used to convert a fiber link 
to the RJ-45 port of a NIC card or workstation, the up-link switch is 
set to the “=” position. 
Category 5 twisted-pair cable should be used to connect to 
the TX port. 
Separate LEDs indicate LINK status for each port, lighting 
when the associated cable segments are properly connected at 
both ends and are ready for data transmission. Collisions (if any) are 
not detected, and 15Es operate properly when connected to either 
FDX or HDX ports. 15Es do not respond to auto-negotiation FLP requests. 
The Magnum 15E Media Converters meet the IEEE 802.3u specifications and are 
interoperable with other standards-compliant Fast Ethernet products. They have a 
115vac 60Hz or 230vac 50Hz external power supply that plugs into a nearby AC 
wall socket or power strip. The compact packaging, about the size of a bar of 
soap, does not require rack space and can be conveniently mounted in an office, 
or out-of-the-way wiring closet area. Metal brackets for optional wall mounting 
are included. 
The Magnum 15E Media Converters and other Magnum products are designed and 
manufactured in the USA and backed by a three-year warranty.
