To connect a fiber optic segment, attach the fiber labeled 2 to the
adapter’s Transmit port (light gray). Attach the fiber labeled 1 to
the adapter’s Receive port (dark gray).
At the other end of the fiber optic cable, attach the fiber labeled 1 to
the Transmit port of the applicable device. Attach the fiber labeled
2 to the Receive port of the applicable device. At this time you
should check to see that the adapter’s Link LED is lit. If the LED is
not lit, verify that power is on for the PC, and check that the power
is on for the device at the end of the fiber optic cable.
Verify that the fiber optic strands are “crossed over” at the far end
device, Transmit to Receive by checking the labeling on each
strand. Verify that the fiber connection meets the dB loss
specifications outlined in Appendix A, Technical Specifications. If
a link still has not been established, contact Cabletron Systems
Technical Support (see Section 1.2, Getting Help).
