V1 Series Media Converters

Guidelines for the
SML Mode for
V1
Example
Scenarios in SML
Mode
26
The DMC1000/100 V1 series media converters have the SML feature 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.
Note
For the V2 series media converter, see "V2 Series Media
Converters" on page 27.
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 SML mode:
The DMC1000/100 V1 series media converter is set to either the

SML mode on or off.
Use the DIP switch to select ON or OFF.

When two media converters are connected in pairs, turn the SML

mode on. See "Media Converters in Pairs in SML Mode" on
page 30.
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 V1 series media
converter behaves with SML on and SML off:
