Verify that the 100BASE-TX device at the other end of the twisted 
pair segment is powered up.

Verify that the RJ45 connector on the twisted pair segment has the 
proper pinouts.

Check the cable for continuity.

Make sure that the twisted pair connection meets dB loss and cable 
specifications outlined in 

Confirm that the crossover switch is in the correct position.

The FE-100FX and FE-100F3 have an SC style network port (see 

). Cabletron Systems supplies fiber optic cable that uses SC 

style connectors which are keyed to ensure proper crossing over of the 
transmit and receive fibers.

Remove the protective plastic covers from the fiber optic ports on the 
applicable port on the module and from the ends of the connectors.

An odd number of crossovers (preferably one) must be 
maintained between devices so that the transmit port of one 
device is connected to the receive port of the other device and 
vice versa.

If the fiber optic cable being used has SC style connectors that 
do not resemble MIC style connectors, or has SC connectors 
on one end and a different type on the other, such as ST 
connectors, ensure that the proper crossing over occurs. 

The FE-100F3 uses Class 1 lasers. Do not use optical 
instruments to view the laser output. The use of optical 
instruments to view laser output increases eye hazard. When 
viewing the output optical port, power must be removed from 
the network adapter.
