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 for:
•
Redesigning the motherboard for alternate components if failure rates
exceed reliability expectations.
•
Estimating repair rates and spare parts requirements.
MTBF data is calculated from predicted data @ 55
°
C.
The MTBF prediction for the motherboard is 213,209 hours.
