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 MTBF for the D915GUX and
D915GHA boards is 110,262 hours.
