Design issues:

 

1) CAN SMB subsystem currently not stable due to mixed 3.3V/5V SMB system : incompatibility to 5V CMOS signal thresholds on Fujitsu CAN controller. Affects: control daughter only. To be resolved by adding level translators.

 

2) SystemACE issue resolved: JEM1.3 will have 16-bit access only, address lines will be swapped.

3) Front panel design / connector positions might be non-final. Cannot be checked unless TripleEase panels/handles become available. Not available from the manufacturer as samples. Have been ordered, not expected to be delivered in 2005. affects : main board. Can anyone help ?
