amount of airflow required for their specific application and environmental conditions. Intel 
Corporation cannot be held responsible, if components fail or the server board does not 
operate correctly when used outside any of its published operating or non-operating limits. 
11.2  MTBF 
The following is the calculated Mean Time Between Failures (MTBF) 40°C (ambient air). These 
values are derived using a historical failure rate and multiplied by factors for application, 
electrical and/or thermal stress and for device maturity. You should view MTBF estimates as 
“reference numbers” only.
