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 A-weighted sound pressure level at the bystander position per section 4.3 of ISO 9296 (1988) and measured in accordance to ISO
7779 (2010). The system is placed in a 24U rack enclosure, 25cm above a reflective floor.
Prominent tone: Criteria of D.6 and D.11 of ECMA-74 12th ed. (2012) are followed to determine if discrete tones are prominent. The system
is placed in a 24U rack enclosure and the acoustic transducers are at front & rear bystander positions.
