Link Test/MissingLink Button
The Link Test/MissingLink button allows you to perform a link test on the
ports on the media converter. This button also allows you to activate the
MissingLink feature on the unit. Both features are describe in the following
section.
Link Test. The link test is a fast and easy way for you to test the connections
between the ports on the media converter and the 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, and be able to focus on the fiber optic
cable and node where the problem resides.
A link test is performed when the button is in the LNK TST (OUT) position. For
instructions on performing a link test, refer to “Testing the Installation” on
page 11.
Note
Performing a link test does not interfere with a media converter’s ability
to pass network traffic.
