2.2 Product Description
Magnum 14E Fast Ethernet Media Converters offer a convenient, cost-effective and
graceful way to incorporate fiber media into a 100BASE-TX Ethernet network. Each Magnum
14E supports both full- and half-duplex mode transparently so that an attached RJ-45 switch or
hub operates at its highest performance level. For support of “N-way” auto-negotiating
switches, a manual AN/reg switch on the Magnum 14E allows the user to manually enable
either (a) “AN” for auto-negotiation, where the 14E transmits applicable auto-negotiation Fast
Link Pulses (FLPs) from the RJ-45 port to the connected 10/100 switch port at Link-enable, or
(b) “reg” regular media converter mode, no auto-negotiation.
Magnum 14E Media Converters are designed for quick and easy installation even in
very tight spaces. Media cables are easily attached. Magnum 14E Media Converters feature an
up-link switch on the TX port to eliminate the need for a special cross-over cable when

connecting the TX port to a switch or hub. Because of their compact size, Magnum Media
Converters can be Velcro®-mounted on an office wall or the side of a desk or cabinet. The
external power supply, 115vac 60Hz or 230vac 50Hz, plugs into a nearby AC wall socket or
power strip. Each 14E Media-Converter features a two full sets (front and side) of LEDs that
convey essential status information in any mounting arrangement. See Section 4.1, LED
Indicators, for LED function information.
Magnum 14E Media Converters are designed to operate at high ambient temperatures
over an extended period, making them some of the most reliable in the industry. Their high-
strength fabricated metal packaging shields against Radio Frequency Interference (RFI) and
Electromagnetic Interference (EMI), avoiding interference with other nearby electronic
devices.

The Magnum 14E units comply with the IEEE 802.3u (100BASE-TX and 100BASE-
FX) specification for 100 Mb/sec traffic via shielded (STP) or unshielded twisted pair (UTP)
segments.
The Link Pass-Through feature is especially
desirable for use in managed networks, and is
standard in all 14E’s. Magnum 14E-ST models
are equipped with one multi-mode fiber-ST and
one RJ-45 connector for connection into
100BASE-FX segments.
