CAUTION: Wear a grounding device and observe electrostatic dischargeprecautions when setting the 4-position switch. Failure to observe this caution
could result in damage to, and subsequent failure of, the media converter.
Set the 4-Position Switch
•The 4-position switch is located
on the side of the media
converter.
•Use a small flat-blade screwdriver
or a similar device to set the
recessed switches.
•Refer to the drawing for the
locations of the four individual
switches.

CAUTION: Wear a grounding device and observe electrostatic dischargeprecautions when setting the jumper. Failure to observe this caution could
result in damage to, and subsequent failure of, the media converter.
Set the Jumper
The Far-End Fault jumper is labeled “FE” for enable
Far-End Fault and “FD” for disable Far-End Fault (see
page 6).
EnableA fault on the fiber link causes the media
converter to transmit a Far-End Fault signal.
DisableNo Far-End Fault signal is transmitted when
a fault occurs.
To set the jumper:
1.Using a small screwdriver, remove the four (4) screws that secure the
cover and carefully remove the cover from the media converter.
2.Locate the jumper on the circuit board labeled “FE” and “FD”.
3.Using small needle-nosed pliers or similar device, move the jumper to
the desired position. (Refer to the drawings above.)
4.Carefully replace the cover on the media converter and replace the four
(4) screws that secure the cover to the media converter.

Product Features
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to automatically
configure itself to achieve the best possible mode of operation over a link.
The media converter broadcasts its speed (10 Mb/s or 100 Mb/s) and duplex
capabilities (full or half) to the other devices and negotiates the best mode of
operation. Auto-Negotiation allows quick and easy installation because the
optimal link is established automatically. No user intervention is required to
determine the best mode of operation.
A scenario where the media converter is linked to a non-negotiating device is
a case where the user may want to disable Auto-Negotiation. In this instance,
the mode of operation will drop to the least common denominator between
the two devices (e.g. 10 Mb/s, half-duplex). Disabling this feature gives the
user the ability to force the connection to the desired speed and duplex mode
of operation.
AutoCross™
When the AutoCross feature is activated, it allows either straight-through
(MDI) or crossover (MDI-X) copper cables to be used when connecting to
10Base-T or 100Base-TX devices. AutoCross determines the characteristics of
the connection and automatically configures the unit to link up, regardless if
the copper cable is MDI or MDI-X configuration. (This feature does not
require operator intervention.)
Far-End Fault
When a fault occurs on an incoming fiber link (1), the media converter
transmits a Far-End Fault signal on the outgoing fiber link (2). In addition the
Far-End Fault signal also activates the Link Pass-Through feature, which, in
turn, disables the link on the copper portion of the network (3) and (4).

Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See page 1 (front cover) for the cable specifications
for the different SBFTF10xx-15x models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex Network (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A
collision domain is the longest path between any two terminal devices, e.g. a
terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled “CollisionDomains” on the Transition Networks website at: www.transition.com.
