MEDIA CONVERSION

The J/E-PSW-FX-01 series 2-port bridging media converter allows
connection of 10BASE-T Ethernet

™

or 100BASE-TX Fast Ethernet™twisted­pair copper network devices to network devices on a 100BASE-FX Fast
Ethernet

™

fiber network.

RATE CONVERSION

The J/E-PSW-FX-01 series 2-port bridging media converter allows
connection of 10Mb/s terminal devices on a 10BASE-T legacy Ethernet

™

copper network to 100Mb/s terminal devices on a 100BASE-FX Fast
Ethernet

™

fiber network.

DISTANCE EXTENSION

In a half-duplex Ethernet

™

or half-duplex Fast Ethernet™environment, the
J/E-PSW-FX-01 series 2-port bridging media converter extends network
distances by segmenting CSMA/CD collision domains so that the 10BASE­T 5-Segment Rule or the 100BASE-TX /100BASE-FX 512-Bit Rule (see
pages 6-7) applies separately to each CSMA/CD collision domain.

In a full-duplex Ethernet

™

or full-duplex Fast Ethernet™environment, the
J/E-PSW-FX-01 series 2-port bridging media converter extends network
distances to the physical cable limitations imposed by the selected
twisted-pair copper cable and the selected fiber cable (see page 10).

CONGESTION REDUCTION

The J/E-PSW-FX-01 series 2-port bridging media converter does not
forward collision signals or error packets from one CSMA/CD collision
domain to another, improving baseline network performance. And the
bridging media converter filters packets destined for local devices, also
reducing network congestion.

INSTALLATION

Connect Twisted-Pair Copper Cable to UTP/STP Connector
(10BASE-T/100BASE-TX)

CAUTION: 10BASE-T/100BASE-TX connections between a hub and
the media converter require crossover configuration cable. 10BASE-T
/100BASE-TX cable connections between the media converter and a
terminal, transceiver or NIC require straight-through configuration
cable. (See page 7.) Failure to observe this caution will cause data
transfer to fail.

10BASE-T AND THE ETHERNET COLLISION DOMAIN

• Refer to the 5-Segment Rule (page 6) before installing half­duplex 10BASE-T cable.

• Installing full-duplex twisted-pair cable avoids collision
domain considerations; distances remain ≤ 100 meters.

100BASE-TX AND THE FAST ETHERNET COLLISION DOMAIN

• Refer to the 512-Bit Rule (page 7) before installing half-duplex
100BASE-TX cable.

• Installing full-duplex twisted-pair cable avoids collision
domain considerations; distances remain ≤ 100 meters.

• NOTE: A Fast Ethernet collision domain can have only ONE
CLASS I repeater OR TWO CLASS II repeaters.

INSTALLING CABLE

To install 10BASE-T or 100BASE-TX cable:

1. Locate or build 10BASE-T or 100BASE-TX cables:

• that are 803.2 compliant (page 10)

• configured as straight-through or as crossover, according to
site requirements (page 7)

• with RJ-45 plug connectors installed at both cable ends.

2. Connect RJ-45 plug connector at one end of 10BASE-T or
100BASE-TX cable to bridging media converter RJ-45 jack
connector.

3. Connect RJ-45 plug connector at other end of 10BASE-T or
100BASE-TX cable to RJ-45 jack connector on network device.

FAULT ISOLATION AND RECOVERY

If a bridging media converter fails, ask the following questions:

1. Is the power LED on the media converter illuminated?

NO

• Is the power cord properly installed in the media converter
and at the external power source?

• Does the external power source provide power?

• Contact Technical Support: [phone]

YES

• Proceed to step 2.

2. Is the Link LED illuminated on a port with twisted-pair installed?

NO

• Check UTP cables for proper connection/pin assignment.

• Contact Technical Support: [phone]

YES

• Proceed to step 3.

3. Is the Link LED illuminated on a port with fiber installed?

NO

• Check fiber cables for proper connection.

• Verify that TX and RX cables are connected to RX and TX
ports, respectively, on 100BASE-FX device.

• Refer to Tech Tips available at: http://www.transition.com

• Contact Technical Support: [phone]

YES

Use the status LEDs on the media converter to monitor media
converter and fiber network connections.

100 Illuminated LED indicates fiber (FX) or copper (TX)

100 Mb/s operation.

LIN K Steady LED indicates
ACT(ivity) fiber (FX) or copper

(TX) link connection;
flashing LED
indicates fiber (FX) or
copper (TX) network
activity.

FDX Illuminated LED

indicates full-duplex network connection; dark LED
indicates half-duplex network connection.

P(o)W(e)R Steady LED indicates connection to external AC

power.

Connect Fiber Cable to TX/RX Connector (100BASE-FX)S

100BASE-FX AND THE FAST ETHERNET COLLISION DOMAIN

• Refer to the 512-Bit Rule (pages 8-9) before installing half-

duplex 100BASE-FX cable.

• Use full-duplex fiber cable to avoid collision domain

considerations and to extends network distances

• Note that a Fast Ethernet collision domain can have ONLY

ONE CLASS I repeater OR TWO CLASS II repeaters.

INSTALLING CABLE

To install 100BASE-FX cable:

1. Locate or build 100BASE-FX cables:

• 100BASE-FX compliant (page 13)

• with male transmit (TX) and receive (RX) fiber connectors

installed at both cable ends.

2. Connect cable with connector installed at TX location on media
converter to RX location on attached device.

3. Connect cable with connector installed at RX location on media
converter to TX location on attached device.

Power the Bridging Media Converter

1. Install power adapter cord at back of media converter.

2. Connect power adapter plug to AC power.

3. Verify that media converter is powered by observing illuminated
LED(s).

The two active pairs in a 10BASE-T or 100BASE-TX
network are pins 1 & 2 and pins 3 & 6. Use only
dedicated wire pairs (such as blue/white &
white/blue, orange/white & white/orange) for the
active pairs.

The two wires in each pair of the cable must be
twisted together for the entire length of the segment
and kept twisted to within approximately 1/2 inch of
any connector to ensure the integrity of the signal­carrying characteristics of the unshielded wire pair.

To calculate the round trip delay in bit-times between a station (DTE)
and the bridging media converter, find the longest path between the
station and the bridging media
converter. Calculate the round
trip delay for each cable
segment by multiplying the
length of the cable (in meters)
by the delay per meter (in bit­times (BT)). Calculate the total
round trip delay by taking the
sum of all the cable delays plus station (DTE) and repeater delays. If
the result is less than or equal to 512 bit-times, the path passes the test.
NOTE: Installing the bridging media converter in the network
separates collision domains; the 512-bit rule applies separately to
each 100BASE-TX or 100BASE-FX half-duplex collision domain.

A segment is the cable connection between interfaces. A
transmission path between any two terminal devices
(including the Transition Networks’ bridging media
converter) in the same collision domain can consist of no
more than five segments. Assign segment numbers to
cable connections to determine the network device
separated from the bridging media converter by the
greatest number of segments. Define a segment path
between that network device and the bridging media
converter by labeling the cable connection to the
bridging media converter “segment 1” and numbering
each segment in the path to the network device up to
“segment n” (n = total number of segments † 5). Verify
that no segment path in the collision domain contains
more than 5 segments. NOTE: Installing the bridging
media converter in the network separates collision
domains; the 10BASE-T 5-Segment Rule applies
separately to each 10BASE-T collision domain.
