MDI/MDI-X Switch
The
NML/LNK TST Switch
The NML/LNK TST (Normal/Link Test) switch, located on the front panel, establishes a fiber/twisted pair link in the test position.
The default position of the switch is IN, which is the normal (NML) operating mode and enables the MissingLink feature. With the switch in the OUT or Link Test mode (LNK TST) position, the MissingLink feature is disabled and the optical transmitter TX is forced on. The NML LED lights when the NML/ TST LNK switch is in the default (IN) operating position.
Note
Using the Link Test mode does not interfere with the media converter’s ability to pass network traffic.
