Smart MissingLink™ (SML)
The Smart MissingLink™ (SML) feature makes a connection problem
visible and helps you identify where troubleshooting is required.
When one of the Ethernet connections to the media converter fails, SML
disables the other port and causes its LED to blink to notify where a
problem is occurring.
This section explains following scenarios:
“Media Converter with SML Off” on page 28
“Standalone Media Converter in SML Mode” on page 29
“Media Converters in Pairs in SML Mode” on page 30
Media Converter
with SML Off
Following are example scenarios when the media converter is connected
between two end nodes and SML is off.
Note
The scenarios with SML off apply only to the V1 series media
converters. The V2 series media converter does
not
have the SML
off option.
Figure 12 shows media converter and end node LINK/ACT LED behavior
with SML off under normal conditions.

Figure 13 shows media converter and end node LINK/ACT LED behavior
with SML off with a fiber connection down.
