Dell PowerEdge R250 is a rack-mount server appropriate for attended data center environment. With typical loading condition in 23°C ± 2 °C ambient temperature, R250 is suitable for office environment. Acoustical performance is provided in terms of four configurations: Minimum, Economy, Typical, and Feature Rich. Configuration details are provided in Table 9, and acoustical experience data associated with each configuration of PowerEdge R250 are provided in Table 10.
Although the R250 is designed for use in data centers, some users may have needs to deploy it in a quieter setting. In this case, please reference Tips for acoustically sensitive environments. Note however that in most cases, the idle air mover speed of the system cannot be lowered without changing the configuration of the system, and sometimes even a configuration change may not reduce idle air mover speeds.

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.
