Power consumption and heat output varydepending on the number and type ofoptional features installed and thepower-management optional features inuse.2. These levels were measured in controlledacoustical environments according to theprocedures specified by the AmericanNational Standards Institute (ANSI) S12.10and ISO 7779 and are reported inaccordance with ISO 9296. Actualsound-pressure levels in a given locationmight exceed the average values statedbecause of room reflections and othernearby noise sources. The declaredsound-power levels indicate an upper limit,below which a large number of computerswill operate.Chapter 1. Introduction 7
