Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when setting or installing the media converter. Failure to observe this caution could
result in damage to, and subsequent failure of, the media converter slide-in-module.
Six-position switch
The six-position switch is located on the circuit board of the media converter. Use a
small, flat-blade screwdriver (or a similar device) to set the switch according to the
site the requirements (see the drawing below).
1. Twisted-Pair Auto-Negotiation
UP Enable Auto-Negotiation for the copper connection .
DOWN Disable Auto-Negotiation for the copper connection.
Note: Switches 2 and 3 will not function when twisted-pair Auto-Negotiation is
enabled (switch 1 = UP). The media converter adopts the speed and mode
settings from the device at the other end of the copper link.
2. Twisted-Pair 10Mbs/100Mbs
UP Set copper connection speed to 100Mbs.
DONW Set copper connection speed to 10Mbs.
3. Twisted-Pair Full/Half Duplex
UP Operate in full-duplex mode .
DOWN Operate in half-duplex mode of the attached device.
4. Fiber Auto-Negotiation
UP Enable Auto-Negotiation for the fiber connection .
DOWN Disable Auto-Negotiation for the fiber connection.
5. (not used)
6. Link Pass-Through
UP Enable Link Pass-Through.
DOWN Disable Link Pass-Through.
2. TP 10Mbs/100Mbs
3. TP Half/Full-Duplex
4. Fiber Auto-Negotiation
5. (not used)
1. TP Autonegotiation
6. Link Pass Through

AutoCross™ jumper
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X)
cables to be used when connecting to 10Base-T, 100Base-TX, or 1000Base-T
devices, such as hubs, transceivers, or network interface cards (NICs). AutoCross
determines the characteristics of the cable connection and automatically configures
the unit to link up, regardless of the cable configuration.
The AutoCross jumper is located on the media converter’s circuit board (labeled E and
D—see the figures to the right).
Note: Use small needle-nose pliers to set the jumper.
Enabled Either straight-through or crossover cable can be
used for all twisted-pair copper links.
Disabled Straight-through or crossover twisted-pair cable,
depending on installed site devices, MUST be
installed at EACH twisted-pair copper link.
Note: Factory default is “enable.” Transition Networks recommends leaving the
device in the “enable” mode.

Hardware/software jumper
The hardware/software jumper is located on the circuit board (labeled H and S—
see figure to the right.)
Note: Use small needle-nose pliers to set the jumper.
Hardware The media converter mode is determined by the
6-position switch settings.
Software The media converter mode is determined by the
most-recently saved, on-board microprocessor
settings.
