Installation

Installing the Cable

Fiber

1. Locate or build 100Base-FX compliant fiber cable with male, two-stranded TX
to RX connectors installed at both ends.

2. Connect the fiber cables to J/FE-CF-03 media converter as described:

• Connect the male TX cable connector the female TX port.

• Connect the male RX cable connector to the female RX port.

3. Connect the fiber cables to the other device (another media converter, hub,
etc.) as described:

• Connect the male TX cable connector the female RX port.

• Connect the male RX cable connector to the female TX port.

Installation -- Continued

Copper

1. Locate or build 100Base-TX compliant copper cables with male, RJ-45
connectors installed at both ends.

2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the
J/FE-CF-03 media converter.

3. Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on
the other device (switch, workstation, etc.).

Set the Two-Position Switch

A two-position switch (located on the back of the media monverter) allows
selection of Auto-Negotiation and Full- or Half-Duplex. Use a small, flat-blade
screwdriver (or a similar device) to set the switch according to the site requirements
see the drawing below.

Auto-Negotiation:

UP Enable Auto-Negotiation

DOWN Disable Auto-Negotiation

Full/Half Duplex:

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.

Power the media converter

AC power:

1. Install the power adapter cord to the back of the media converter.

2. Connect the power adapter plug to AC power.

3. Verify that the media converter is powered by observing the illuminated LED
power indicator light.

DC power:

Consult the User’s Guide for the Transition Networks SPS1872-xx DC External
Power Supply for powering the media converter.

Operation

Auto-Negotiation

The Auto-Negotiation feature allows the media converter to be used with 100Base­TX ports. Using Auto-Negotiation, the media converter brings up the copper links
in the highest speed and 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. See page 1 (front cover) for the cable specifications for the
different J/FE-CF-03 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 “Collision
Domains” on the Transition Networks website at:

http://www.transition.com/learning/whitepapers/colldom_wp.htm

those specified herein may result in hazardous radiation exposure.

CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232,
RS422, RS485, DS1, DS3, Video Coax, etc., are intended to be connected to intra­building (inside plant) link segments that are not subject to lightening transients or
power faults. Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB,
RS232, RS422, RS485, DS1, DS3, Video Coax, etc., are NOT to be connected to inter­building (outside plant) link segments that are subject to lightening transients or power
faults. Failure to observe this caution could result in damage to equipment.

*MTBF is estimated using the predictability method. This method is based on MIL­217F at 25°C ambient temperature, typical enclosure heat rise of 10°C, and nominal
