Chapter 1: Overview

V1 and V2 Series Media Converters

The DMC1000/100 series media converters have two versions: V1 and

V2. Both V1 and V2 have Smart MissingLink™ (SML). In addition to SML,

the Missing Link (ML) feature is added to the V2 series media converters.

SML passes a link status from one port to the other so that user’s

managed endpoints can detect a failure at links where the endpoints are

not directly connected. SML is intended for use when the media

converters are installed in pair, connecting two copper endpoints, as

shown in Figure 9.

Figure 9. Two Media Converters in Pair

Note

For detailed information about SML, see “Smart MissingLink™

(SML)” on page 28.

SML helps identify a link problem in two media converters in pair;

however, when SML is used in the media converter in standalone, SML

may cause problems in some situations.

Figure 10 illustrates a situation where a fiber port on the media converter

is connected to a certain switch. When the copper link fails, the fiber link

goes up and down and the switch detects it as a problem with the fiber

link. As a result, the switch disables the fiber port so that the fiber port

cannot reconnect even when the copper link is back.

Figure 10. Possible Situation with Standalone Media Converter with SML

When encountering the problem, you either change the switch setting or

turn off SML on the media converter.
