Reliability Information

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 can be used when estimating repair rates and spare parts requirements.
MTBF data is calculated from predicted data @ 55 C.
The MTBF prediction for the MS440GX motherboard is 129,574 hours.
