Table 2. MAX5 expansion module features and operating specifications (continued)Acoustical noise emissions:For maximum system configurations(32 DIMMs installed)v Sound power (idling): 6.2 belsv Sound power (operating): 6.2 belsv Sound pressure (idling): 48 dBAv Sound pressure (operating): 48dBASize:v Height: 4.4 cm (1.73 in.)v Depth: 72.4 cm (28.5 in.)v Width: 48.3 cm (19.0 in.)v Weight: approximately 12.8 kg(28.2 lb) for a standard unit; whenfully configured, 15.4 kg(33.9 lb)Environment:v Air temperature:– Enclosure on: 10° to 35°C (50°to 95°F); altitude: 0 to 914.4 m(3000 ft). Decreased systemtemperature by 0.75° for every1000 ft. increase in altitude.– Enclosure off: 5° to 45°C (41° to113`°F)– Shipment: -40°C to +60°C(-40°F to 140°Fv Humidity:– Enclosure on: 20% to 80%;maximum dew point: 21°C(70°F)– Enclosure off: 8% to 80%;maximum dew point: 27°C(80°F)– Shipment: 5% to 100%v Particulate contamination:Attention: Airborne particulatesand reactive gases acting alone orin combination with otherenvironmental factors such ashumidity or temperature might posea risk to the server. For informationabout the limits for particulates andgases, see “Particulatecontamination” on page 105.Heat outputApproximate heat:v Minimum configuration: 314 Btuper hour (92 watts)v Maximum configuration 2048 Btuper hour (600 watts)Electrical input:v Sine-wave input (50 - 60 Hz)requiredv Input voltage low range:– Minimum: 90 V ac– Maximum: 136 V acv Input voltage high range:– Minimum: 198 V ac– Maximum: 264 V acv Approximate input kilovolt-amperes(kVA):– Minimum: 0.1 kVA– Maximum: 0.6 kVANotes: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 proceduresspecified by the AmericanNational Standards Institute(ANSI) S12.10 and ISO 7779 andare reported in accordance withISO 9296. Actual sound-pressurelevels in a given location mightexceed the average stated valuesbecause of room reflections andother nearby noise sources. Thedeclared sound-power levelsindicate an upper limit, belowwhich a large number ofcomputers will operate.What the MAX5 offersThe IBM MAX5 for System x (MAX5) memory expansion module provides severalfeatures for easy operation, including the following features:v Customer replaceable units (CRUs)The major CRUs in the MAX5 expansion module are memory modules, fans, andpower supplies. See “MAX5 components” on page 72 for the supported MAX5components.v Light path diagnostics LEDsThe MAX5 expansion module has light path LEDs (front and rear) to indicatehardware, scaling, and power problems.Chapter 1.
