Table 31 provides maximum case temperatures for the board 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 board.

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 Desktop Board
D925XHY is 105,577 hours.
