Dell26PowerEdge R515 Technical GuideMaximum ShockOperating One shock pulse in the positive z axis (one pulse on each side ofthe system) of 31G for 2.6ms in the operational orientationStorage Six consecutively-executed shock pulses in the positive andnegative x, y, and z axes (one pulse on each side of the system)of 71G for up to 2msSquare wave shock of 32G @ 270 in/secondAltitudeOperating -15.2 to 10,668m(-50 to 35,000ft)Note: For altitudes above 2950 feet, the maximum operatingtemperature is derated 1°F/550 ft.Storage -15.2 to 10,668m(-50 to 35,000ft)The airborne contaminant level is class G2 or lower as defined by ISA-S71.04-1985.4.5 ENERGY STAR ComplianceENERGY STAR® qualified configurations can be accessed from the ENERGY STAR Compliance results landingpage on Dell.com.4.6 ThermalThe thermal design of the PowerEdge R515 includes the following: Closed loop thermal control algorithm: This method uses feedback temperatures to dynamicallydetermine proper fan speeds. Comprehensive thermal management: The PowerEdge R515 controls system cooling fan speed basedon several different responses from critical component sensors, such as processor temperature, DIMMtemperature, IOH temperature, inlet ambient temperature, and system configurations. The thermalmanagement adjusts proper cooling ability for the system according to what the system really needs. Optimized Ventilation: The R515 chassis has a custom ventilation design for optimized air flow path.Each component and peripheral is ensured sufficient air for cooling. Redundant Cooling: The R515 (12-HDD system) has redundant cooling, which means that other fanstake over for cooling if a fan fails.4.7 AcousticsThe acoustical design of the PowerEdge R515 reflects adherence to Dell’s high sound quality standards.Sound quality is different from sound power level and sound pressure level in that it describes how humansrespond to annoyances in sound, like whistles, hums, etc. One of the sound quality metrics in the Dellspecification is prominence ratio of a tone as shown in Table 6 and 0.Fan speeds and noise levels ramp up during the boot process to add a layer of protection for componentcooling if the system were not to boot properly. Hardware configurations affect system noise levels. Dell’sthermal control provides for optimized cooling with varying hardware configurations, as shown in thefollowing tables.
