Troubleshooting
General
1. Ensure power is supplied to the media converter. Only
the Perle provided power supply may be used.
2. Ensure the remote device’s fiber connection type is
compatible with the media converter. If using a simplex
fiber connection, ensure that you have both an Upstream
(U) and Downstream (D) media converter.
3. Ensure all cabling is of the correct type and is in good
working order.
4. For duplex fiber connections, ensure the RX and TX has
been reversed between the two media converters.
No connectivity
If unable to get full connectivity with all DIP switches in the
UP position, this procedure is recommended for
troubleshooting.
Method 1
1. Set the Link Pass-Through mode to Standard on both
media converters. Leave all other switches in the Up
position.
2. Connect the copper device to the copper port on the
media converter. The LKC LED light indicates good
copper connection. If the LKC LED is not lit, then check
the copper cable and the attached device.
3. Repeat for the far end media converter.
4. Connect the fiber cable to both media converters. The
LKF LED indicates good fiber connection. If no LKF LED
then check the fiber cabling. Ensure the transmitter and
receiver pairs are crossed.
5. Return units to desired configuration.
