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
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 Intel NUC Board D54250WYB
and Intel NUC Board D34010WYB is 66,640 hours.
