Power consumption and heatoutput vary depending on thenumber and type of optionalfeatures installed and thepower-management optionalfeatures in use.2. These levels were measured incontrolled acoustical environmentsaccording to the proceduresspecified by the American NationalStandards Institute (ANSI) S12.10and ISO 7779 and are reported inaccordance with ISO 9296. Actualsound-pressure levels in a givenlocation 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 computerswill operate.4 IBM System x3550 Type 7978 and 1913: Problem Determination and Service Guide
