DESCRIPTION
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
NOTES
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.
