INSTALLATION
(continued)
Connect to Power
• Install Power Adapter cord at back of media converter.
• Connect Power Adapter 3-prong plug to AC power.
• Verify that media converter is powered by observing illuminated LED(s).
OPERATION
After installation, the media converter should function without operator
intervention.
Status LEDs:
Use the status LEDs to monitor media converter operation in the network.
NOTE: lluminated PRI(mary) and/or SEC(ondary)
LEDs indicate media converter connection to
external power.
PRI Copper Primary Port - Steady green
LED indicates primary copper port is
being selected
by internal
control logic
SEC Copper
Secondary Port -
Steady green
LED indicates
secondary
copper port is
being selected
by internal control logic
RXC Receive Copper Port - Steady green
LED indicates valid data is being
detected on copper interface
SDC Signal Detect Copper - Steady green LED indicates Link
established on copper port selected
PRI: Fiber Primary Port - Steady green LED indicates primary fiber
port is being selected by internal control logic
SEC Fiber Secondary Port - Steady green LED indicates secondary
fiber port is being selected by internal control logic
SDF Signal Detect Fiber - Steady green LED indicates optical signal
present on fiber port selected
RXF Receive Fiber Port - Steady green LED indicates non-IDLE
symbols are being detected on fiber interface
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. Are the PRI(mary)/SEC(ondary) LEDs on the media converter
illuminated or alternating between between primary and
secondary ports?
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?
• *Are PST switch settings on two media converters installed in series
in the network set to different values?
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the 100BASE-TX SDC (Signal Detect/Copper) LED
illuminated?
NO
• Check UTP cables for proper connection.
• Verify MDI/MDI-X switch position.
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Proceed to step 3.
3. Is the 100BASE-FX SDF (Signal Detect/Fiber) 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
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
YES
• Contact Technical Support at (800) 260-1312/ (800) LAN-WANS.
*NOTE: Setting PST switch settings on two media converters installed in series
in the network to different values (11 seconds and 5 seconds) ensures, in the
event of common power failure or similar incident, a sufficient delay in the time
required to establish each link so that communication between the media
converters is guaranteed.
