Specifications (system) The following table contains the environmental specifications for the Netfinity 3000 server. Notes 1. The following 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. 2. 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. Size Depth: 445 mm (17.5 in.) Width: 200 mm (7.9 in.) Height: 492 mm (19.4 in.) Weight Maximum configuration (as shipped): 17.3 kg (38 lb) Standard configuration (as shipped): 15 kg (33 lb) Environment Air temperature: - System on: 10° to 35°C (50° to 95°F) at altitude 0-915 m (3000 ft) 10° to 32°C (50° to 90°F) at altitude 915-2134 m (3000-7000 ft) - System off: 10° to 43°C (50° to 110°F) Humidity: - System on: 8% to 80% - System off: 8% to 80% Heat Output Approximate heat output in British thermal units (Btu) per hour: - Maximum configuration (as shipped): 306 Btu/hour (90 watts) - Maximum configuration (theoretical)1: 1564 Btu/hour (460 watts) Electrical Input Sine-wave input (50/60 Hz) is required Input voltage: - Low range: - Minimum: 90 V ac - Maximum: 137 V ac - High range: - Minimum: 180 V ac - Maximum: 265 V ac - Input kilovolt-amperes (kVA) (approximately): - Maximum (configuration as shipped): 0.70 kVA Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use. Acoustical Noise-Emission Values Average sound-pressure levels: - At operator position: - 35 dBA idle - 40 dBA operating 1 Under typical maximum configurations, the heat output will be substantially below the theoretical maximum. 56 Netfinity Server HMM
