on a closet wall or metal cabinet, or by using the metal panel mounting clips included.
The FT14H Hardened unit features a sealed metal case which is also used as a
heat sink. No air inflow is required for cooling, so the FT14H resists dust, dirt, moisture,
smoke and insects, and is plenum rated. Choices of models for external AC or internal
DC power are available. Storage temperature rating is up to –40°C to +75°C depending
on the power source used. The FT14H is suitable for temperature un-controlled outdoor
applications. Mounting options include panel-mounting, DIN-rail, or rack-mount tray.
The FT14-series Media Converters offer a graceful way to convert and
transmit data among twisted pair, and Fiber (Multi or Single Mode) network cabling

FT14 and FT14H 10Mb Media Converters Installation and User Guide (09/04)
The up-link (or crossover) switch on the RJ-45 port simplifies cable installation. All fiber
models operate in transparent full- or half-duplex mode, supporting matched sets of
either mode type, i.e., attached devices are either both full-duplex or both half-duplex.
Magnum FT14-series 10Mb Media Converters are designed for quick and easy
installation even in very tight spaces. Media cables are easily attached to the
corresponding Media Converter or any other device. Using the Uplink Switch feature
eliminate the use of cross-over cable, see sec 4.6 for details. Because of their compact
size, Magnum Media Converters can be Velcro®-mounted on an office wall or the side
of a desk or cabinet. Mounting options include panel-mounting, DIN-rail and rack-mount
tray ( MC14-TRAY) that neatly holds the units and associated power supplies.
The standard “1-per-unit” external power supply plugs into a nearby AC wall
socket or power strip. The FT14H (Hardened) media converter is also available with

extended temperature power supply AC/DC (External/Internal) to qualify for un-
controlled and Industrial application. Each converter features two full sets of LEDs that
convey essential diagnostic and status information at any angle. See Section 4.1 and 4.4,
for power supply and LED function specifications.
All of the Magnum FT14-series Media Converters comply with the IEEE 802.3
10BASE-T specification for 10 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 FT14 and FT14H
models.
Note: experience shows that the maximum number of 10Mb Media Converters
that can be used in series is three. The cumulative signal noise from 4 or more
units together in series may cause packet alignment errors.

2.4 Applications for FT14’s and hardened FT14H’s
The primary function of a 10Mb Ethernet Media Converter is to permit two
different 10Mb media types to coexist inexpensively within the same network by
allowing data to be transmitted and received between different media types.
Magnum FT14-series Media Converters are typically used where 10BASE-T
networking equipment is being installed in un-controlled temp environment and require
longer distance. Magnum FT14-series Media Converters have an external AC power
supply and internal DC Power supply, enabling them to be used to convert signals among
media that does not have a power source as part of the cabling system, such as twisted
pair and Fiber. Equipped with wide variety of options of AC and DC power supply and
components for higher un-controlled temp qualify the FT14’s for use in office locations
as well as industrial and even outdoor applications.

FT14 and FT14H 10Mb Media Converters Installation and User Guide (09/04)
2.5 Full / Half-duplex capability
For 10Mb FT14-series Media converters, the twisted-pair to fiber
combination is capable of full-duplex (i.e., simultaneously transmitting and
receiving on the same cable segment) operation. Full-duplex is rarely required
at 10Mb, but might occasionally be desired to connect a 10Mb RJ-45 Switching
Hub port over a fiber link to a full-duplex RJ-45 NIC in a remote server, or to
connect one port of a full-duplex Switching Hub via fiber to another full-duplex
10Mb RJ-45 Switching Hub port.
All the FT14-series operate in transparent half-and full-duplex mode. For half-duplex
traffic, the FT14-series work correctly but do not detect or indicate collisions.
2.6 Link Pass-through, features and options.
The Magnum FT14 Media Converters, regular, non-hardened models, come
without the Link Pass-through feature unless it is specially ordered with the “LP” model.
In this regard, the FT14 models operate the same as the smaller companion product, the
Magnum TF14.
By comparison, the FT14H hardened models come with Link-Pass-through as a
standard feature in order to be used with switches in industrial networks. In managed

networks, the LINK signal on a managed switch (or hub) port is used as an indicator that
the attached cable segment is installed and operable. The network manager, using the
SNMP agent, can troubleshoot the cabling by examining the LINK status on each port.
This works fine as long as all of the cabling is twisted pair.
When a twisted-pair to fiber media converter is introduced, the FT14 regular
models of these products (not the Magnum FT14H’s) treat each attached cable segment
as a separate entity. LEDs on

separately indicate LINK on
each port, enabling an installer
to see the LINK (or no-LINK)
status of each port and each
piece of cable independently.
This is nice for the network
installer, but it introduces a
discontinuity for the managed
network software which wants

order to maintain optimum network performance. (See also Technical Specs, Maximum
Standard Ethernet Segment Distances, Section 1.1 of this manual.)
When installing the Magnum FT14-series Media Converter, it is important to consider
the combined overall segment length of both of the attached media types. The overall
segment length is calculated by adding together the segment lengths on both sides of the
Magnum Media Converters. Cable segment length on each side of the Media Converter
is measured as a percentage of the maximum allowable standard media distance for the
given media type. The percentages, when added together, must not exceed 100%.

Media Distance Formula for Magnum Media Converters:
X% + Y% < 100%
Where X = The segment distance on one side of the Magnum Media Converter
divided by the Standard Maximum Media Distance for that media type, x 100%.
Where Y = The segment length on the other side of the Magnum Media Converter
divided by the Standard Maximum Media Distance for that media cabling type, x 100
A Distance Calculation Example:

allowable distance for UTP 10BASE-T media (100 m) [55/100 x 100% = 55%]. The
total of the two percentages (39% + 55%) is 94%, which is allowable.
Note 1: Where more than one media converter is used in one segment run, the
percentages for all of the cabling lengths in the run must be added together and must not
exceed 100%.
Note 2: If the total segment distance calculation result is greater than 100%, consider
using a Magnum Repeater so that each cable type can be 100% of its maximum allowed
length.
Note 3: The maximum number of 10Mb Media Converters that can be used in series is
three. The cumulative noise from four or more units together causes packet alignment
errors.

3.6 Connecting Ethernet Media
Connecting Ethernet media to the Magnum FT14 Series Media Converter is
very simple and straightforward. Using proper media segment, simply attach the cable
end to the appropriate connector.
See Sections 4.4 for details of the LEDs on the media converter models.
3.6.1
Connecting Twisted Pair (RJ-45 ports)
The following procedure describes how to connect a 10BASE-T twisted pair
segment to the RJ-45 port on the Magnum Media Converters. The procedure is the same
for both unshielded and shielded twisted pair segments.
1.
Using standard 10BASE-T media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the Magnum Media Converter.

FT14 and FT14H 10Mb Media Converters Installation and User Guide (09/04)
2.
Connect the other end of the cable to the corresponding device. Use the LINK
LED to ensure proper connectivity by noting that the LED will be illuminated
when the units are powered and proper connections established. If the LINK
LED is not illuminated, change the setting of the up-link switch (See Section
4.6 for up-link switch information.) If this does not help, ensure that the cable
is connected properly at both ends and is not defective.
3.6.2
Connecting Fiber Optic multi-mode, single mode (half- and full-
duplex)
The following procedure applies to 10BASE-FL multi-mode and single mode
applications using the FT14-series Media Converters. All have ST-type fiber connectors.
The FT14S single-mode differs from the other fiber media converters in terms of the
maximum distance allowed. The others are used for a multi-mode fiber segment lengths
of up to 2km. The FT14S is used for single-mode fiber segments of up to 10km in
length. The following table (continued next page) is provided for general information:

Procedure for connecting multi-mode and single-mode fiber cables:
1. Before connecting the fiber cable, remove the protective dust caps from the tips of the
connectors on the media converter. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note: One strand of the duplex fiber optic cable is coded using color bands at
regular intervals; you must use the color-coded strand on the associated ports
at each end of the fiber optic segment.
3. Connect the Transmit (TX) port (light colored post) on the Magnum Media Converter to the
Receive (RX) port of the remote device. Begin with the color-coded strand of the cable for
this first TX-to-RX connection.
4.
Connect the Receive (RX) port (dark-colored post) on the product to the Transmit
(TX) port of the remote device. Use the non-color coded fiber strand for this.

5. The LINK LED corresponding to the fiber port on the front of the product will illuminate
(for standard non-Link-Pass-through models) when a proper connection has been
established at both ends (and when power is ON in the units at each end). If LINK is not lit
after cable connection, the normal cause is improper cable polarity. Swap the fiber cables
on the product connector to remedy this situation.
6. For the Link Pass-through model, connection is the same except that the LINK indication
will not be present unless LINK is made for the cables on both sides.
3.6.3
Power Budget Calculations for Fiber Media Magnum FT14-series
Receiver Sensitivity and Transmitter Power are the parameters necessary to
compute the power budget. To calculate the power budget of different fiber media
installations, the following equations should be used:
OPB (Optical Power Budget) = PT(min) - PR(min)
where PT = Transmitter Output Power, and PR = Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125µm (M.m) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km

5.4 Shipping and Packaging Information
Should you need to ship the unit back to GarrettCom, please follow these instructions:
1. Package the unit carefully. It is recommended that you use the original

sheet or bag for shipping protection. ( You may retain all connectors and this
Installation Guide.)
CAUTION: Do not pack the unit in Styrofoam "popcorn" type packing material.
This material may cause electro-static shock damage to the unit.
2. Clearly mark the Return Material Authorization (RMA) number on the
outside of the shipping container.
