4.4 Auto Negotiation on High-Density Media Converter System II Layer 2
Modules
L2 modules include the feature Auto Negotiation. When Auto Negotiation is
enabled, the module negotiates as a 100 Mbps full-duplex device. If the
connected device can operate at 100 Mbps full-duplex, a link is established.
Auto Negotiation (DIP Switch #1) is enabled by default.
If the twisted pair port on the other device does not have the ability to Auto
Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto
Negotiation must be disabled. Half- and full-duplex settings must be set
manually and match on both devices.
The following diagram shows a typical application and with three possible
configurations.
