Physical specifications - small desktop model Dimensions Height: 88 mm (3.4 in.) Width: 305 mm (12.0 in.) Depth: 380 mm (14.9 in.) Weight Minimum configuration as shipped: 8.2 kg (18 lb) Maximum configuration: 8.6 kg (19 lb) Environment Air temperature: System on: 10° to 35° C (50° to 95° F) System off: 10° to 43° C (50° to 110° F) Maximum altitude: 2134 m (7000 ft) Note: The maximum altitude, 2134 m (7000 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: 8% to 80% System off: 8% to 80% Heat output (approximate) in British thermal units (Btu) per hour: Minimum configuration: 187.8 Btu/hr (55 watts) Maximum configuration: 307.3 Btu/hr (90 watts) Airflow Approximately 0.25 cubic meters per minute (9 cubic feet per minute) maximum Acoustical noise-emission values Average sound-pressure levels: At operator position: Idle: 38 dBA Operating: 43 dBA At bystander position - 1 meter (3.3 ft): Idle: 33 dBA Operating: 37 dBA Declared (upper limit) sound-power levels: Idle: 3.75 bels Operating: 4.99 bels Electrical input Input voltage: Low range: Minimum: 90 V ac Maximum: 137 V ac Input frequency range: 57-63 Hz Voltage switch setting: 115 V ac High range: Minimum: 180 V ac Maximum: 265 V ac Input frequency range: 47-53 Hz Voltage switch setting: 230 V ac Input kilovolt-amperes (kVA) (approximate): Minimum configuration as shipped: 0.085 kVA Maximum configuration: 0.120 kVA 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: The computer is classified as a Class A or Class B digital device. See the Quick Reference for further information about this classification. 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. 6 User Guide

Acoustical noise-emission values
Average sound-pressure levels:
At operator position:
Idle: 38 dBA
Operating: 43 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 33 dBA
Operating: 37 dBA
Declared (upper limit) sound-power levels:
Idle: 3.75 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.
