Perle SR-100 Fast Ethernet Media Converter Installation Guide 15
Troubleshooting
General
•
Ensure power is supplied to the media converter.
•
Ensure both devices on either end of the fiber are compatible.
If using a single 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
operating condition.
•
For dual-stranded fiber connections, ensure the RX and TX
has been reversed between the 2 media converters.
No connectivity
If unable to get full connectivity with all DIP switches in the UP
position, the following procedure is recommended for
troubleshooting.
Method 1
1.
Set the Link mode to Standard (SW3 – Down) on both media
converters. Leave all other switches in the Up position.
2.
Connect the near end device to the copper connection. The
LKC LED 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.
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
back and passed through the fiber, once again, to pass through
the local converter to the copper link.
