Link Test, MissingLink, and Smart

MissingLink Functions
Link Test
The link test is a fast and easy way for you to test
the connections between the media converter ports 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, and so
be able to focus your troubleshooting efforts on the
cable or end-node where the problem resides.
MissingLink
The MissingLink feature enables the two ports on the
media converter to pass the ‘Link’ status of their
connections to each other. When the media converter
detects a loss of connection to an end-node, the media
converter shuts down the connection to the other port,
thus notifying the end-node that the connection has been lost.
Smart MissingLink
The Smart MissingLink feature performs exactly the
same function as MissingLink with one additional
feature. When a link is lost on a port, the LINK LED of
the port which still has a valid connection to its endnode
starts to blink. This allows you to quickly
determine which port still has a valid connection (LINK
LED blinking) and which port has lost its connection
(LINK LED off).
