General Information

For more detailed information on the VME bus backplane, refer to the 
VME Extensions Standard, VITA 1.1-199X, which can be found at 
http://www.vita.com.

Safety and Regulatory Compliance

All systems integrated by Motorola meet the standards claimed for those 
systems with regard to electromagnetic interference (EMI), radio 
frequency interference (RFI), and overall safety. It is possible, however, to 
install circuit boards and drives in the MVME956AC enclosure that 
produce a system not in compliance with the applicable emission limits. 

Note

It is the integrator’s responsibility to design a payload that 
meets the desired standards. 

When Motorola integrates a payload into the MVME956AC enclosure, it 
is often necessary to make changes to the payload in order for the system 
to pass RFI standards. The following is a list of conditions that in general 
must be met in order to achieve compliance with RFI standards: 

At a minimum, the chassis must be connected to earth ground 
through the safety ground wire in the power cord to meet safety and 
other requirements. 

All external I/O cables should be high-quality shielded types with 
metal shell connectors. 

Connectors on VME modules should be metal shell types, 
connected to earth ground. This is accomplished through the 
conductive panels in contact with the chassis rails. 

All VME modules should have conductive panels to ensure a good 
RF ground with the conductive chassis rails. 

Blank panels with EMI gaskets should be installed over all unused 
chassis slots to ensure there are no RF leaks in the chassis.
