4. At the other end of the fiber optic cable, attach the fiber pair to the 
transmit and receive ports of the device.
If link indicators are present for the fiber optic connection, check that they 
are ON. If an indicator is present but not ON, that port does not have a 
valid link. Perform each of the following steps until you reach a resolution 
of the problem and achieve a link.
Check that the device at the other end of the link is ON.
Verify proper cross-over of the fiber strands. Try swapping the transmit 
and receive connections at only one end of the link.
Verify that the fiber connection meets the dB loss specifications 
outlined in Appendix A, FOMIM Specifications.
If you are still unable to establish a link, attempt to make the connection 
between the devices with another fiber optic cable. If this is unsuccessful, 
contact Cabletron Systems Technical Support.
