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.
