Note:
1
Chassis design must provide proper airflow to avoid exceeding the processor maximum case
temperature.
Disclaimer Note: Intel Corporation server boards contain a number of high-density VLSI and
power delivery components that need adequate airflow to cool. Intel ensures through its own
chassis development and testing that when Intel
®
server building blocks are used together, the
fully integrated system will meet the intended thermal requirements of these components. It is
the responsibility of the system integrator who chooses not to use Intel
®
developed server
building blocks to consult vendor datasheets and operating parameters to determine the 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.
9.2 MTBF
The following is the calculated Mean Time Between Failures (MTBF) 30 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.
Calculation Model: Telcordia Issue 1, method I case 3
Operating Temperature: Server in 30° C ambient air
