Table 35 provides maximum case temperatures for the 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.

2.12 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 board is
99,721 hours.
