H. Acoustics
The acoustical design of the PowerEdge R610 reflects the following:

level and sound pressure level in that it describes how humans respond to annoyances in sound,
like whistles, hums, etc. One of the sound quality metrics in the Dell specification is prominence
ratio of a tone, and this is listed in the table below.

for optimized cooling with varying hardware configurations. Most typical configurations will
perform as listed in the table below. However some less typical configurations and components
can result in higher noise levels, for example, a system configured with a PERC6/E card (noted
in table below). (Please note that dBA values are not additive.)

After power is connected to the power supplies, initialization of power supply
communication with the server’s fan control firmware takes place and assesses if
cooling is required in standby mode. It is therefore normal for chassis fan #1 to
operate at full speed for approximately 30 seconds after power is connected to
thesystem.Thefanwillrampdowntoafullstopafterthistimeperiodin<_25°C
