The le interface provides access to the 10 Mb/s Ethernet network via the AMD Am7990 Local Area Network Controller for Ethernet (LANCE) chip set.

Different cards and machines have different kinds of connectors, as follows:

AUI/DIX
Standard 15 pin connector
10BaseT
UTP, also known as twisted pair

By default, the system will select the media type automatically, but the ifconfig(8) command can be used to force the media selection. The media types are shown below:

media autoselect
Attempt to autoselect the media type (default)
media 10base5
Use the AUI connector
media 10baseT
Use the twisted pair connector

Some SBus models, in particular the 501-1450 and 501-1881, have dip switches which must be changed to select between the BNC and AUI modes. For BNC, set 1-6 ON, 7-8 OFF; for AUI set 1-6 OFF, and 7-8 ON.
