Connecting and Terminating
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 actions 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
FDDI Network Requirements.
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.
To remove the SC connector from the port, grasp it firmly with thumb and
forefinger and pull it straight out of the port. There will be some initial resistance
before the inner latching mechanism allows the connector to slip. Do not pull
quickly or rock the connector back and forth, as damage to the connector or port
may result.
Once the connector is removed, place the protective plastic covers over the fiber
optic port on the module, and over the ends of the ferrules of the SC Connector.
