Troubleshooting
If network traffic problems are suspected
1.
If the power LED is not illuminated, check the power connections.
2.
If the CentreCOM Multiport repeater is receiving power, check that
terminations are correct on all BNC ports.
3.
If any ports are disconnected verify that they are switched off line by
ensuring that the Auto/Manual switch is in the Manual position.
4.
If only one segment is non-functional then try another port to determine
if the port or cable segment is at fault.
If the SQE/COL LED is constantly illuminated
1.
Check for a missing (open) or shorted terminator.
Excessive flickering of the SQE/COL LED will indicate too many frame
Collisions on the segment. This may be caused by an overloaded segment or
by a marginal cable or connection.
If no ports are functional and the Power LED is illuminated
1.
Try a known good repeater to test and validate the segment.
2.
