System specifications Size Depth: 646 mm (25.4 in.) including front bezel Width: 430 mm (16.9 in.), 484 mm (19.1 in) including mounting flanges Height: 44 mm (1.73 in.) Weight Maximum configuration (as shipped): 10.43 kg (23.0 lb) Maximum configuration with slide rails attached: 11.34 kg (25.0 lb) Environment Air temperature: - System on: - At altitude 0-914 m (3000 ft): 10° to 35°C (50° to 95°F) - At altitude 914 m (3000 ft)-2134 m (7000 ft): 10° to 32°C (50° to 90°F) - System off: −40° to 70°C (−40° to 158°F) Humidity: - System on: 8% to 80% - System off: 8% to 80% Heat output7 Approximate heat output in British thermal units (Btu) per hour: - Maximum configuration (as shipped): 306 Btu/hour (90 watts) - Maximum configuration (theoretical)6: 545.6 Btu/hour (160 watts) Electrical input7 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): 0.3 kVA Acoustical noise-emission values8 Average sound-pressure levels: - 49 dBA idle - 50 dBA operating Declared (upper limit) sound power levels: - 6.4 bels idle - 6.5 bels operating 6 Under typical maximum configurations, the heat output will be substantially below the theoretical maximum. 7 Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use. 8 These levels were measured in controlled acoustical environments according to ISO 7779, and are reported in accordance with ISO 9296. The declared sound power levels indicate an upper limit, below which a large portion of machines operate. Sound pressure levels in your location might exceed the average 1-meter values stated because of room reflections and other nearby noise. 8 Netfinity® 4000R User's Handbook
