2. Attach one fiber to the applicable receive port on the module. Insert
the ST connector into the port with the alignment slot on the connector

3. Attach the other fiber of the pair to the applicable transmit port on the
module. Use the same procedure for insertion of the ST connector.
4. Attach the other end of the fibers to the appropriate transmit and
receive ports of the other device being connected.
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 crossover 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 B.
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.
