Chapter 3. Physical Specifications System Specifications System specifications are provided to assist you with the setup of your computer. Desktop Model Dimensions Height: 128 mm (5.0 in.) Width: 450 mm (17.7 in.) Depth: 450 mm (17.7 in.) Weight Minimum configuration as shipped: 9.9 kg (22 lb) Maximum configuration: 11.3 kg (25 lb) Environment Air temperature: - System on: 10° to 32°C (50° to 90°F) - System off: 10° to 43°C (50° to 110°F) Humidity: - System on: 8% to 80% - System off: 8% to 80% Maximum altitude: 2134 m (7000 ft) Electrical Input Sine-wave input (50 to 60 Hz) is required Input voltage: - Low range: - Minimum: 90 V ac - Maximum: 137 V ac - Voltage switch setting: 115 or 115 V - High range: - Minimum: 180 V ac - Maximum: 265 V ac - Voltage switch setting: 230 or 230 V - Input kilovolt-amperes (kVA) (approximately): - Minimum configuration as shipped: 0.08 kVA - Maximum configuration: 0.52 kVA Note: Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use. Heat Output Approximate heat output in British thermal units (Btu) per hour: - Minimum configuration: 245 Btu/hr (70 watts) - Maximum configuration: 700 Btu/hr (204 watts) Airflow Approximately 0.56 cubic meters per minute (20 cubic feet per minute) Acoustical Noise-Emission Values Average sound-pressure levels: - At operator position: - 34 dBA idle - 37 dBA operating - At bystander position-1 meter (3.3 ft): - 29 dBA idle - 32 dBA operating Declared (upper limit) sound power levels: - 4.5 bels idle - 4.9 bels operating Note: These levels were measured in controlled acoustical environments according to procedures specified by the American National Standards Institute (ANSI) S12.10 and ISO 7779, and are reported in accordance with ISO 9296. Actual sound-pressure levels in your location might exceed the average values stated because of room reflections and other nearby noise sources. The declared sound power levels indicate an upper limit, below which a large number of computers will operate. Chapter 3. Physical Specifications 21
