Dell R210 II manual Acoustical Specifications, Bels DBA Supply, Bels DBA Tones Supply

Dell

∙Hardware configurations affect system noise levels: Dell‘s thermal control provides for cooling flexible to varying hardware configurations. Acoustical performance associated with two common configurations is listed in Table 6.

∙Noise ramp and descent at boot: Fan speeds (and corresponding noise levels) ramp up during the boot process to add a layer of protection for component cooling, in the event that the system does not boot properly.

The acoustical performance for minimum and typical configurations of the PowerEdge R210 II are shown in Table 6.

Definitions

Standby: AC Power is connected to power supplies but the system is not turned on.

Idle: Reference ISO7779 (1999) definition 3.1.7; system is running in its OS but no other specific activity.

Active Hard Drives: An operating mode per ISO7779 (1999) definition 3.1.6; Section C.9 of ECMA-74 9th ed. (2005) is followed in exercising the hard disk drives.

Stressed Processor: An operating mode per ISO7779 (1999) definition 3.1.6; SPECPower set to 50% loading is used.

LwA–UL:The upper limit sound power level (LwA) calculated per section 4.4.2 of ISO 9296 (1988) and measured in accordance to ISO 7779 (1999).
