WARNING: Visible and invisible laser radiation when open. Do not stare into the
beam or view the beam directly with optical instruments. Failure to observe this
warning could result in an eye injury or blindness.
WARNING: Use of controls, adjustments or the performance of procedures other than
those specified herein may result in hazardous radiation exposure.
CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232,
RS422, RS485, DS1, DS3, Video Coax, etc., are intended to be connected to intra-
building (inside plant) link segments that are not subject to lightening transients or
power faults. Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB,
RS232, RS422, RS485, DS1, DS3, Video Coax, etc., are NOT to be connected to inter-
building (outside plant) link segments that are subject to lightening transients or power
faults. Failure to observe this caution could result in damage to equipment.
Troubleshooting
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 PWR (Power) LED on the media converter illuminated?
NO
• Is the media converter inserted properly into the chassis?
• Is the power cord properly installed in the chassis and in the grounded AC
outlet?
• Does the grounded AC outlet provide power?
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 2.
2. Is the RXC LED illuminated when data is sent across the
RS485/422 copper link?
NO
• Check the RS485/422 copper cable for proper connection.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 3.
3. Is the RXF (fiber link) LED illuminated?
NO
• Disconnect and reconnect the fiber cables to restart the initialization
process.
• Verify that the TX and RX cables on the media converter are connected to
the RX and TX ports, respectively, on the other media converter.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 4.
4. Does the data fail to move across the link, even though both RXC and
RXF LEDs are illuminated?
YES
• Check switches 5 and 6 for proper configuration and check the RS485/422
cables for proper connection.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
