Table 31 provides maximum case temperatures for the Desktop Board D865PCK components that

are sensitive to thermal changes. The operating temperature, current load, or operating frequency

could affect case temperatures. Maximum case temperatures are important when considering

proper airflow to cool the Desktop Board D865PCK.

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 D865PCK MTBF

is 101,425 hours.
