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 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, the 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 the units to the desired configuration. Plug the other end of the power cord into an appropriate power outlet.
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
