Other Information
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.
