Troubleshooting
If you experience any problems with the adapter, first: ascertain that
the appropriate driver is loaded; that the proper grade of cable is
employed for the network connection; and that the supporting hub is
properly qualified for the application (such as 100Base-FX).
The DFE-500FX Adapter features four LED indicators:
• FULL/HALF DUPLEX MODE
Steady green indicates the adapter is operating in Full Duplex
mode. A dark LED indicates the adapter is operating in Half
Duplex mode.
• LINK
Steady green indicates good linkage between the DFE-500FX
and its supporting hub.
• ACTIVE
Flashing green indicates activity (transmitting or receiving)
within the adapter.
• COLLISION
A yellow flash indicates data collisions in the segment.
Intermittent flashing of the collision LED is normal.
