Footnotes:
Idle means the state in which the product is doing nothing but running OS, and values for Operating are the maximum of acoustical output for
active HDDs or active processors.
LwA-UL is the upper limit sound power levels (LwA) calculated per section 4.4.1 of ISO 9296 (1988) with data collected in accordance with
ISO 7779 (2010) from a single sample with a total 0.3 bel production deviation applied.
LpA is the average bystander position A-weighted sound pressure level calculated per section 4.3 of ISO 9296 (1988) and measured in
accordance with ISO 7779 (2010). FX chassis is installed in a Dell 42-U rack such that the bottom of the Enclosure is at 25-cm from the floor
of the chamber.
Prominent tone: Criteria of D.6 and D.11 of ECMA-74 12th ed. (2012) are followed to determine if discrete tones are prominent. FX chassis is
installed in a Dell 42-U rack such that the bottom of the Enclosure is at 75-cm from the floor of the chamber. The acoustic transducers are at
front and rear bystander positions.
