Technical Reference 2.13 Reliability The Mean Time Between Failures (MTBF) prediction is calculated using component and subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction Procedure, TR-NWT-000332, Issue 4, September 1991. 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 Desktop Board D845GVFN MTBF is 149979.68 hours. 2.14 Environmental Table 40 lists the environmental specifications for the Desktop Board D845GVFN. Table 40.
