3.7 Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
sub-assembly random failure rates. The calculation is based on the Telcordia SR-332,
Method I Case 1 50% electrical stress, 55 ºC ambient. The MTBF prediction is used to
estimate repair rates and spare parts requirements.
The MTBF data was calculated from predicted data at 55 ºC. The Intel
®
Embedded
Board D2700 has an MTBF of at least 314,073 hours.
