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 cord properly installed in the chassis and at the
external power source?
•
Does the external power source provide power?
•
Contact Technical Support: (800) 260-1312.
YES
•
Proceed to step 2.
2.
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.
YES
•
Proceed to step 3.
3.
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.
YES
•
Proceed to step 4.
4.
Is Data Transfer Failing?
YES
•
Verify local twisted-pair copper connection by starting a local
copper loopback (setting the loopback switch on the local media
converter to copper, if in hardware mode, or entering the local
copper loopback command, if in software mode) and then using a
Bit Error test unit to run a Bit Error test.
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 ohm 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 ohm cable.
