SpecificationsThis section lists the physical specifications for your computer.DimensionsHeight: 398 mm (15.67 in.)Width: 180 mm (7.08 in.)Depth: 402 mm (15.82 in.)WeightMinimum configuration as shipped: 7.6 kg (16.8 lb)Maximum configuration: 9.97 kg (22 lb)EnvironmentAir temperature:System on: 10° to 35°C (50° to 95° F)System off: 10° to 43°C (50° to 110° F)Maximum altitude: 2134 m (7000 ft)Note: The maximum altitude, 2134 m (7000 ft), isthe maximum altitude at which the specified airtemperatures apply. At higher altitudes, themaximum air temperatures are lower than thosespecified.Humidity:System on: 8% to 80%System off: 8% to 80%Electrical inputInput voltage:Low range:Minimum: 100 V acMaximum: 127 V acInput frequency range: 50–60 HzVoltage switch setting: 115 V acHigh range:Minimum: 200 V acMaximum: 240 V acInput frequency range: 50–60 HzVoltage switch setting: 230 V acInput kilovolt-amperes (kVA) (approximate):Minimum configuration as shipped: 0.08 kVAMaximum configuration: 0.30 kVANote: Power consumption and heat output varydepending on the number and type of optionalfeatures installed and the power-managementoptional features in use.Heat output (approximate) in British thermal units (Btu)per hour:Minimum configuration: 257 Btu/hr (75 watts)Maximum configuration: 785 Btu/hr (230 watts)AirflowApproximately 0.68 cubic meters every minute (24cubic feet every minute) maximumAcoustical noise-emission valuesFor microprocessors less than 2.8 GHz:Average sound-pressure levels:At operator position:Idle: 28 dBAOperating: 35 dBAAt bystander position - 1 meter (3.3 ft):Idle: 25 dBAOperating: 33 dBADeclared (upper limit) sound-power levels:Idle: 4.0 belsOperating: 4.7 belsFor microprocessors greater than or equal to 2.8 GHz:Average sound-pressure levels:At operator position:Idle: 33 dBAOperating: 35 dBAAt bystander position - 1 meter (3.3 ft):Idle: 30 dBAOperating: 33 dBADeclared (upper limit) sound-power levels:Idle: 4.4 belsOperating: 4.7 belsNote: These levels were measured in controlledacoustical environments according to the proceduresspecified by the American National Standards Institute(ANSI) S12.10 and ISO 7779 and are reported inaccordance with ISO 9296. Actual sound-pressure levelsin a given location might exceed the average valuesstated because of room reflections and other nearby noisesources. The declared sound-power levels indicate anupper limit, below which a large number of computerswill operate.28 User Guide
