3.21J7 & J12 Fast Ethernet

J7 is available as standard on the CPU front-panel and, as an option, J12 may also be available but at the expense of the FireWire interface. The RJ45 interface supports both the 10BaseT and 100BaseTX twisted pair standard.

Note:

 

 

 

 

 

Users taking advantage of the CPU’s rear

 

 

 

 

 

I/O options are advised not to use the

 

 

 

 

 

front-panel interface if the rear interface is

 

 

 

 

 

being used. Possible damage to the board

 

 

 

 

 

could occur and data integrity cannot be

 

 

 

 

 

assured.
