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.
