The declared sound power level is measured according to ECMA 74 and reported according to
ECMA 109. The fan RPM settings for the two operating conditions are determined through
thermal analysis and/or testing prior to the sound power level measurement. To measure the
power supply assembly sound power levels corresponding to the two operating conditions, the
fan in the power supply assembly is powered externally to the two RPM settings. The 45 degree
C inlet temperature is derived based on standard system ambient temperature assumptions (25
degrees C and 35 degrees C), typical temperature rise within the system, and thermal impact of
fan speed control.

Airflow Requirements
The power supply incorporates one 80-mm fan for self-cooling and system cooling. The fan
provides no less than 14 CFM airflow through the power supply when installed in the system.
The cooling air enters the power module from the non-AC side.

Temperature Requirements
The power supply operates within all specified limits over the T
op
temperature range. All airflow
passes through the power supply and not over the exterior surfaces of the power supply.
