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 P(o)W(e)R LED on the media converter illuminated?
NO
• Is the power adapter the proper voltage and cycle frequency for the
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: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 2.
2. Is the 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 other media converter.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
•
Proceed to step 3.
3. Is the SDC (Signal Detect/Copper) LED illuminated?
NO
• Check twisted pair cables for proper connection.
• Check RJ-45 Pinning Switch for correct twisted pair cable
configuration.
• Check integrity of device attached to media converter by twisted-
pair cable.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NOTE:
T1 must be selected ( LEFT
SWITCH SET #4 UP) for RIGHT
SWITCH SET to have any effect.
If E1 is selected ( LEFT SWITCH SET
#4 DOWN), RIGHT SWITCH SET is
ignored and the default is E1
3.0V 120
Ω cable.
If T1 and short haul are
selected (
LEFT SWITCH SET #3
UP, #4 UP), but RIGHT SWITCH
SET is not set to a valid short
haul value, the short haul
default is DSX-1 0’-133’ cable.
If T1 and long haul are
selected (
LEFT SWITCH SET #3
DOWN, #4 UP), but RIGHT
SWITCH SET is not
set to a valid
long haul value,
the long haul
default is 0db
100
Ω cable.
