Troubleshooting
General
•
Ensure power is supplied to the media converter. Only the
Perle provided power supply may be used.
•
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.
•
Ensure all cabling is of the correct type and is in good working
order.
•
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.
Method 2:
The fiber connection can also be verified by configuring the remote
media converter for loopback mode. The LKF LEDs on both media
converters should be lit. Data should pass through the local
converter, over the fiber connection to the remote media
converter. At the remote media converter, the data will be looped
