8 Troubleshooting
Link LED does not lit after cable is connected to the port.
．
Verify that the other end of the cable is connected to a device that is powered on and on-line.
100BASE-TX port Link LED is lit, Collision LED is blinking, but traffic is irregular.
．
Check that the attached device is not set to dedicated Full-Duplex. (Some devices use a
physical or software switch to change Duplex modes. Auto-Negotiation may not recognize this
type of Full-Duplex setting).
Note:
For any change to DIP switch settings to take effect, the Switch must be turned “OFF”,
then “ON” again.
Always check that:
．
Cable and link distances are within the network’s specifications.
．
Overall network diameters are within the network’s specification.
