Types 8110, 8112, 8113, 8114, 8115, 8153, 8166, 8167, 8168, 8169, and 8170 This section lists the physical specifications. Dimensions Height: 432 mm (17.0 in.) Width: 178 mm (7.0 in.) Depth: 450 mm (17.7 in.) Weight Minimum configuration: 10.5 kg (23 lb) Maximum configuration: 13.5 kg (30 lb) Environment Air temperature: System on: 10° to 35°C (50° to 95° F) System off: 10° to 60°C (50° to 140° F) Maximum altitude: 914 m (3000 ft) Note: The maximum altitude, 914 m (3000 ft), is the maximum altitude at which the specified air temperatures apply. At higher altitudes, the maximum air temperatures are lower than those specified. Humidity: System on: 10% to 80% System off: 10% to 90% Electrical input Input voltage: Low range: Minimum: 100 V ac Maximum: 127 V ac Input frequency: 50/60 Hz Voltage switch setting: 115 V ac High range: Minimum: 200 V ac Maximum: 240 V ac Input frequency: 50/60 Hz Voltage switch setting: 230 V ac Input kilovolt-amperes (kVA) (approximate): Minimum configuration as shipped: 0.09 kVA Maximum configuration: 0.32 kVA Heat output (approximate) in British thermal units (Btu) per hour: Minimum configuration: 256 Btu/hr (75 watts) Maximum configuration: 1058 Btu/hr (310 watts) Airflow Approximately 1.13 cubic meters per minute (40 cubic feet per minute) maximum Acoustical noise-emission values Average sound-pressure levels: At operator position: Idle: 29 dBA Operating: 33 dBA At bystander position - 1 meter (3.3 ft): Idle: 25 dBA Operating: 30 dBA Declared (upper limit) sound-power levels: Idle: 4.0 bels Operating: 4.3 bels Note: These levels were measured in controlled acoustical environments according to the 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 a given 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. 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. Chapter 3. General information 41
