Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when setting the switches and jumper. Failure to observe this caution could result in
damage to, and subsequent failure of, the media converter.
Set the DTE/DCE Switch
The DTE/DCE switch is located on the side of the media converter. How the
DTE/DCE switch is set depends on the type of device connected to the media
converter:
• DTE (Data Terminal Equipment).
• DCE (Data Communication Equipment).
... and the type of RS-232 cable:
• Straight-through configuration cable.
• Null-modem configuration cable.

SNMP
Use SNMP at an attached terminal or at a remote location to monitor the media
converter by monitoring:
• Local/remote fiber link status
• Local/remote hardware/software mode
• Local/remote loop-back
Also, use SNMP to enter network commands for:
• Local/remote loop-back
See the on-line documentation that comes with Transition Networks FocalPoint™
software for applicable commands and usage at www.transition.com.
Remote Management
The CRS2F31xx-100 can remotely manage the SRS2F31xx-100 (the stand-alone
version of the media converter) or another CRS2F31xx-100. For example, a local
CRS2F3111-100 converter (that is installed in a managed Transition Networks
PointSystem™ chassis) is connected, via fiber, to a remote SRS2F3111-100
converter.
The SNMP section (below) lists the commands that can be used to monitor and
manage both the local and remote media converter.
Note: In a managed network, both the local and remote media converters must be
set to “software” mode.

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 P (power) LED 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 Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
• Proceed to step 2.
2. Is the RX (copper) LED flashing?
NO
• Disconnect and reconnect the RS-232 copper cable to restart the initialization
process.
• Restart the attached device on the other end of the RS-232 cable to restart the
initialization process.
• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
• Proceed to step 3.
3. Is the FL (fiber) LED illuminated?
NO
• Check the fiber cables for proper connection.
• 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 Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
YES
• Proceed to step 4.
4. Is the FL (fiber) LED flashing?
YES
• The media converter is in loop-back mode. To disable the loop-back function in
“Hardware” mode, set the loop-back switch to the "Norm" position. In “Software”
mode, at the SNMP interface, select “disable loop-back” option.
• Contact Tech Support: 1-800-260-1312, Int’l: 00-1-952-941-7600.
NO
• Proceed to step 5.

CRS2F31xx-100
5. Is Data Transfer Failing?
YES
• Verify the local copper connection by starting a local copper loop-back (hardware
mode: set the loop-back switch on the local media converter to “loop”, software
mode: enter the local copper loop-back command) and then use a bit error test unit to
run a bit error test.
• Verify the local fiber connection by starting a remote fiber loop-back (hardware
mode: set the loop-back switch on the remote media converter to “loop”, software
mode: enter the remote fiber loop-back command) and then use a bit error test unit to
run a bit error test.
• Verify the remote copper connection by starting a remote copper loop-back
(hardware mode: set the loop-back switch on the remote media converter to “loop”,
software mode: enter the remote copper loop-back command) and then use a bit error
test unit on the remote end to run a bit error test.
• Verify remote fiber connection by starting a local copper loop-back (hardware
mode: setting the loop-back switch on the local media converter to “loop”, software
mode: enter the local fiber loop-back command) and then use a bit error test unit on
the remote end to run a bit error test.
NO
