Operation of the Intel

 Server Boards S5520HC and/or S5500HCV at conditions beyond those 

shown in the following table may cause permanent damage to the system. Exposure to absolute 
maximum rating conditions for extended periods may affect system reliability.

 Chassis design must provide proper airflow to avoid exceeding the processor maximum case 

. 

: 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. 

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.
