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.

2. Press the RJ45 connector into the port until the click of the locking clip is felt.
Once the locking clip snaps into place, the RJ45 connector will remain in the port.

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
Fiber Optic Network Requirements.
only insert and lock if the raised locking clip of the RJ45 connector is inserted
into the correct location.

The pressure required to perform this should be minimal. If you encounter
resistance or excessive friction, remove the connector and check the port for
obstruction. Also, verify that the connector and the port are of the same type.
