If the serverhas a dual-core microprocessor, atmaximum power reduce the 35°Cby 1°C per 300 m above sea level,or the microprocessor might throttleto remain within the internal thermalspecifications.- 10° to 32°C (50° to 90°F); altitude:914 m to 2133 m (7000 ft.)v Humidity:– Server on: 8% to 80%– Server off: 8% to 80%Electrical input:v Sine-wave input (50-60 Hz) requiredv Input voltage high range:– Minimum: 200 V ac– Maximum: 240 V acv Approximate input kilovolt-amperes (kVA):– Minimum: 0.08 kVA– Maximum: 1.6 kVANotes:1. Power consumption and heat outputvary depending on the number and typeof optional features installed and thepower-management optional features inuse.2. These levels were measured incontrolled acoustical environmentsaccording to the procedures specified bythe American National StandardsInstitute (ANSI) S12.10 and ISO 7779and are reported in accordance with ISO9296. Actual sound-pressure levels in agiven location might exceed the averagevalues stated because of roomreflections and other nearby noisesources. The declared sound-powerlevels indicate an upper limit, belowwhich a large number of computers willoperate.Chapter 1. The System x3850 server 3
