3.21 J6 & J7 Ethernet

J6 is a Fast Ethernet interface from the SiS chipset while J7 [ETH1] is an additional Fast Ethernet
from the dedicated on-board controller. Both RJ45 interfaces are available as standard on the CPU
front-panel and provide support for 10BaseT and 100BaseTX twisted pair standards.

Note:

Users taking advantage of the CPU’s rear

I/O options are advised not to use the

front-panel interface [ETH1] if the rear

interface is being used. Possible damage

to the board could occur and data

integrity cannot be assured.
