V2 Series Media Converters

Guidelines for the
SML and ML
Modes
Example
Scenarios in ML
and SML Modes
The DMC1000/100 V1 series media converters have the SML and ML
features to pass the link status from one port to the other for endpoints,
make a connection problem visible, and help identify where
troubleshooting is required.
The SML mode is for two media converters in pair; the ML mode is for a
media converter in standalone.
Note
For the V1 series media converter, see "V1 Series Media
Converters" on page 26.
Note
To find out whether your device is V1 or V2, see "Differences
Between V1 and V2" on page 25.
Here are guidelines for the ML and SML modes:
The DMC1000/100 V2 series media converter is set to either the

ML or SML mode.
Use the DIP switch to select ML or SML.

Select the ML mode when a media converter is connected

standalone between a fiber endpoint and copper endpoint. See
"Standalone Media Converter in ML Mode" on page 31.
Select the SML mode when two media converters are connected in

pairs. See "Reset the Media Converter" on page 33.
The SML feature of fiber link communication on a link failure can

cause problems with some switches when the fiber port is directly
connected to a switch. The SML mode is intended when the fiber
port is connected to another Allied Telesis media converter.
The following example scenarios explain how the V2 series media
converter behaves in the ML or SML mode:
