Power consumption and heatoutput vary depending on thenumber and type of optionalfeatures that are installed and thepower-management optionalfeatures that are in use.2. These levels were measured incontrolled acousticalenvironments according to theprocedures specified by theAmerican National StandardsInstitute (ANSI) S12.10 and ISO7779 and are reported inaccordance with ISO 9296. Actualsound-pressure levels in a givenlocation might exceed the averagestated values because of roomreflections and other nearby noisesources. The declaredsound-power levels indicate anupper limit, below which a largenumber of computers willoperate.What the memory expansion module offersThe memory expansion module provides several features for easy operation,including the following features:v Replaceable componentsThe major replaceable components in the memory expansion module are dualinline memory modules (DIMMs), fans, and power supplies. See “Memoryexpansion module components” on page 81 for the components that theexpansion module supports.Chapter 1. The System x3850 X5 and x3950 X5 server 23
