Smart
MissingLink
Like MissingLink, the Smart MissingLink feature terminates the link on
the failed port thereby notifying you when a connection has been lost.
Additionally, Smart MissingLink indicates on which port the connection
has failed. This is shown by a blinking LK LED on the good port.
For example, if the network twisted pair cable to the 1000Base-T port on
the media converter were to fail, the LK LED on the 1000Base-X fiber
optic port will blink, indicating a failed connection on the twisted pair
port. The fiber optic port is still able to receive a signal.
The switch notifies the end-node connected to the fiber optic port that
the connection on the twisted pair port has been lost. If the failure had
started with the fiber optic cabling, the LK LED on the twisted pair port
would blink.
The value to this type of network monitoring and fault notification is so
that you can quickly see which port has failed and troubleshoot your
network accordingly.
