What is the function of the Link Test/Missing Link button on a media converter?
The Link Test/Missing Link button allows you to perform a link test on the ports on the media converter. This button also allows you to activate the Missing Link feature on the unit.
Link Test – Performed when the button is in the LINK TST (OUT) position.
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 port and end-node where the problem resides.
Missing Link – Performed when the button is in the M/L ON (IN) position.
The MissingLink feature enables the fiber optic ports on the media converter to pass the “Link” status of their connections to each other. When the media converter detects a problem with one of the ports, such as the loss of connection to an end-node, the media converter shuts down the connection to the other port, thus notifying the node that the connection has been lost.
