24-hour Technical Support: 1-800-260-1312 -- International: 00-1-952-941-7600
Setting the two-position DIP switch
A two-position DIP switch (located on the back of the media converter) supports
selecting Auto-Negotiation and Full- or Half-Duplex. Typically, most installation
will work with both switches in the UP position. Use a small, flat-blade screwdriver
(or a similar device) to set the switches according to the site requirements; see the
illustration and explanation below.
Auto-Negotiation:
UP Enable Auto-Negotiation
DOWN Disable Auto-Negotiation
Full/Half Duplex (functions only when Auto-Negotiation is enabled.)
UP Full Duplex -- Advertises 100 Mb/s full-duplex only during Auto-
Negotiation.
DOWN Half Duplex -- Used primarily when connecting to a hub. Operates at
100 Mb/s in duplex mode of the attached device.
Note: The configuration of the DIP switches should match that of the RJ-45 port
configuration of the connecting device
Full/Half Duplex - UP=Full
Auto-Negotiation - UP=Enable
Installation -- Continued
Copper
1. Locate or build 100Base-TX compliant copper cable with male, RJ-45
connectors installed at both ends.
2. Connect one end of the RJ-45 cable to the J/FE-CF-04 media converter and
the other end to its mating device as shown below.

Powering the media converter
DC power adapter:
1. Insert the power adapter barrel into the barrel connector located on the back of
the media converter, shown above.
2. Connect the power adapter plug into AC power.
3. Observe that the power ON LED is lit.
USB port power:
Use a USB 2.0 Type A to B male-to-male cable to enable powering the media
converter via an active USB port.
Note: When using the USB port to power the media converter, make sure that the
output USB port is turned ON (some laptops and PCs can turn OFF the
USB port).
The media converter can also be powered via the USB port. When powering the
media converter with the power adapter and through the USB power, the media
converter has redundant power (no load balancing which means the device draws
operating current from higher voltage source, adapter or USB). If the power
adapter is removed, the media converter will be powered via the active USB port.
Note: The USB port provides power to the device only; it is not used to transfer
data.

Using status LEDs
Use the status LEDs to monitor the media converter operation in the network.
Power LED ON indicates connection to adapter power or USB power.
Fiber LED ON indicates fiber link connection.
Copper LED ON indicates copper link connection.
LED FLASHING indicates activity.
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to be used with
10/100Base-TX ports. When using Auto-Negotiation, the media converter brings up
the copper link to the highest speed and best duplex mode possible for all attached
network devices.
Full-Duplex network
In a full-duplex network, maximum cable lengths are determined by the type of
cables that are used. (The 512-Bit Rule does not apply in a full-duplex network.) See
front cover for available J/FE-CF-04 models.
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, router,
etc.)
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 “Collision
Domains” on the Transition Networks website at:
http://www.transition.com/learning/white papers
