Localized High Temperature Zones 82 Technical Reference Table 45 provides maximum case temperatures for the Desktop Board D845GEBV2/D845GERG2 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 D845GEBV2/D845GERG2. Table 45.

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 calculations for the Desktop Boards are as follows: · · Desktop Board D845GEBV2 MTBF: 108748 hours Desktop Board D845GERG2 MTBF: 111270 hours 2. 14 Environmental Table 46 lists the environmental specifications for the Desktop Boards D845GEBV2 and D845GERG2.
