2.7 Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Telcordia SR-332,
Method I Case 1 50% electrical stress, 40 ºC ambient. The MTBF prediction is used to
estimate repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 55 ºC. The Intel Desktop Board
DP43BFL MTBF is 440,158.23 hours.
