Installation Troubleshooting - IMC Networks McBasic 10/100 Operation Manual

Installation Troubleshooting

During installation, first test the fiber and twisted pair connections with all
troubleshooting features disabled, then enable these features (if desired) just before
final installation. This will reduce the features' interference with testing.
When working with units where the features cannot be disabled, both the twisted
pair and fiber connections must be established before the link LEDs will light.
To perform a physical loopback test on the Media Converter, have an appropriate
fiber patch cable, and then follow the four easy steps to test:
Step 1 Configure the McBasic 10/100 to Force 100 Mbps mode.
Step 2 Connect the media converter to the twisted pair device with a twisted pair
cable.
Step 3 Loop a single strand of fiber from the transmit port to the receive port of
the media converter.
Step 4 Verify that both the twisted pair and fiber links on the converter. Refer to
the LED Operation section.
Use caution when conducting a loopback test. It is possible to create a network loop if
connecting the media converter's twisted pair port to an active network. IMC Networks
recommends connecting the twisted pair cable to a computer when performing this type of
test.
