2.8 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,
Issue 2; Method I, Case 3, 55 ºC ambient. The MTBF prediction is used to estimate
repair rates and spare parts requirements. The MTBF for the Intel Desktop Board
DH61AGL is 61,767 hours.
