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 ?
