Media Converter in Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the
cables used. See page 10 for cable specifications.
NOTE: The 512-Bit Rule described below does NOT apply in a full-duplex
network.
Media Converter in Half-Duplex Network
The 512-Bit Rule applies separately to each collision domain.
USING THE 512-BIT RULE
In a half-duplex network, maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet™collision domain.
(Switches and routers divide the network into separate Ethernet™
collision domains.) The 512-Bit Rule determines maximum distances by
calculating the collision domain round-trip delay in bit-times.
To calculate a collision domain round-trip delay in bit-times, find the
longest path between any two
terminal devices in the collision
domain. Calculate the round
trip delay by multiplying the
length of the cable (in meters)
by the delay per meter (in bit-
times (BT)), then take the sum of
all cable delays plus station
(DTE), repeater, and multi-port
media converter port delays. If
the result is less than or equal to 512 bit-times, the path is good.

INSTALLATION
Set MDI/MDI-X Pushbutton Switch
NOTE: The MDI/MDI-X pushbutton switch is located on the media converter
between the copper and fiber network connectors.
•Set the MDI/MDI-X switch to MDI (DOWN) for copper cable connection
between hub and media converter.
•Set the MDI/MDI-X switch to MDI-X (UP) for copper cable connection
between media converter and terminal, transceiver or network interface
card (NIC).
Install Cable
NOTE: See page 6 for cable specifications and configurations.
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
NOTE: AutoCross™allows the use of either straight-through or crossover
configuration cables.
•Locate or build 100BASE-TX compliant cables (either straight-
through or crossover) with male RJ-45 plug connectors at both
ends.
•Connect male RJ-45 plug connector at one end of cable to media
converter RJ-45 jack connector.
•Connect male RJ-45 plug connector at other end of cable to
100BASE-TX terminal device RJ-45 jack connector.
FIBER
•Locate or build 100BASE-FX compliant fiber cable with male
two-stranded TX to RX connectors at both ends.
•Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on media converter.
•Connect male TX and RX cable connectors at other end of cable
to RX and TX connectors of 802.3 compliant fiber device.
Connect to Power
•Install Power Adapter cord at back of Media Converter.
•Connect Power Adapter plug to AC power.
•Verify that Media Converter is powered by observing illuminated
LED(s).
OERATION
Use the status LEDs next to each connector to monitor media converter
operation in the network.
POWER Steady LED indicates power.
UTP Steady LED indicates 100BASE-TX link.
Flashing LED indicates 100BASE-TX activity.
FX Steady LED indicates 100BASE-FX link.
Flashing LED indicates 100BASE-FX activity.
FAULT ISOLATION and CORRECTION
If the media converter fails, isolate and correct the failure by determining the
answers to the following questions and then taking the indicated action:
1. Is the Power LED on the media converter illuminated?
NO
•Is the power adapter the proper type of voltage and cycle frequency
for AC outlet?
NOTE: Refer to the “Power Supply Requirements”on page 7.
•Is the power adapter properly installed in the media converter and
in the outlet?
•Contact Technical Support at [phone]/ (800) LAN-WANS.
YES
•Proceed to step 2.
2. Is the UTP LED illuminated?
NO
•Check UTP cables for proper connection.
•Verify MDI/MDI-X switch position.
•Contact Technical Support at [phone]/ (800) LAN-WANS.
YES
•Proceed to step 3.
3. Is the FX LED illuminated?
NO
•Check fiber cables for proper connection.
•Verify that TX and RX cables on media converter are connected to
RX and TX ports, respectively, on the other 100BASE-FX device.
•Refer to Tech Tips available at: http://www.transition.com
