Dell PowerEdge 450 is a rack-mount server appropriate for attended data center environment. Acoustical performance is provided in terms of four configurations: single-socket, typical (3.5”), typical (2.5”), and Feature Rich. Configuration details are provided in Table 13, and acoustical performance data associated with each configuration of PowerEdge R450 is provided in Table 14. Each configuration has been tested according to Dell acoustical standards for rack-mounted servers.
Lower acoustical output is attainable with proper hardware or software configurations. Tips for acoustically sensitive environments can be helpful for such a situation.

LwA,m: The declared mean A-weighted sound power level (LwA) is calculated per section 5.2 of ISO 9296 with data collected using the methods described in ISO 7779 (2010). Engineering data presented here may not be fully compliant with ISO 7779 declaration requirements.
LpA,m: The declared mean A-weighted emission sound pressure level is at the bystander position per section 5.3 of ISO 9296 and measured using methods described in ISO 7779. The system is placed in a 24U rack enclosure, 25cm above a reflective floor. Engineering data presented here may not be fully compliant with ISO 7779 declaration requirements.
Prominent discrete tones: Criteria of Annex D of ECMA-74 & Prominence Ratio method of ECMA-418 are followed to determine if discrete tones are prominent and to report them, if so.
Idle mode: Idle mode is the steady-state condition in which the server is energized but not operating any intended function.
Operating mode: Operating mode is represented by the maximum of the steady state acoustical output at 50% of CPU TDP or active storage drives for the respective sections of Annex C of ECMA-74.
