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 40 ºC.  The Intel Desktop Board 
DP43BF MTBF is 426,167.42 hours.
