Features and specificationsThe following information is a summary of the features and specifications of theserver. Depending on the server model, some features might not be available, orsome specifications might not apply.Racks are marked in vertical increments of 4.45 cm (1.75 inches). Each incrementis referred to as a unit, or “U.” A 1-U-high device is 1.75 inches tall.Table 1.

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 acoustical environmentsaccording to the procedures thatare specified by the AmericanNational Standards Institute (ANSI)S12.10 and ISO 7779 and arereported in accordance with ISO9296. Actual sound-pressure levelsin a given location might exceedthe average stated values becauseof room reflections and othernearby noise sources. The declaredsound-power levels indicate anupper limit, below which a largenumber of computers will operate.4 IBM System x3250 Types 4364 and 4365: Installation Guide
