The value to this type of network monitoring and fault notification is that
some hubs and switches can be configured to take a specific action in the
event of the loss of connection on a port. In some cases, the unit can be
configured to seek a redundant path to a disconnected end-node or send
out a trap to a network management station, and so alert the network
administrator of the problem.
Note
The MissingLink feature is disabled when you perform a link test
with the NORMAL/LNK TST button. Consequently, to ensure that
the MissingLink feature is activated on the media converter, always
set the button to the NORMAL (IN) position during normal network
operations.
Link Test
A link test is a fast and easy way for you to test the connections between
the ports on the media converter and the end-nodes that are connected to
the ports. If a network problem occurs, you can perform a link test to
determine which port is experiencing a problem, so that you can focus
your troubleshooting efforts on the cable and end-node where the
problem resides.
A link test is performed when the NORMAL/LNK TST button is in the LNK
TST (OUT) position.
Note
Performing a link test does not interfere with a media converter’s
ability to pass network traffic.
