The Intel®Server Board S3420GP may contain design defects or errors known as errata which
may cause the product to deviate from published specifications. Current characterized errata
are available on request.
Intel Corporation server boards contain a number of high-density VLSI and power delivery
components that need adequate airflow to cool. Intel’s own chassis are designed and tested to
meet the intended thermal requirements of these components when the fully integrated system
is used together. It is the responsibility of the system integrator that 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 their published operating or non-operating
limits.
