Specifications This section lists certain specifications for your computer. For the latest specification information, see the User Guide for your computer model and type at: http://www.ibm.com/pc/support/ Dimensions Airflow Width: 12.2 inches (310 mm) Height: 3.35 inches (85 mm) Approximately 14 cubic feet (0.45 cubic meters) per minute Depth: 14.1 inches (358 mm) Weight Minimum configuration as shipped: 7.3 kg (16 lbs) Maximum configuration: 8.5 kg (18.7 lbs) Environment Air temperature: Operating at 0 - 3000 ft (914.4 m): 10° to 35°C (50° to 95°F) Operating at 3000 ft - 7000 ft (2134 m): 10° to 32°C (50° to 89.6°F) Non-operating: 10° to 43°C (50° to 110°F) Humidity: Operating: 8% to 80% Non-operating: 8% to 80% Transit: 8% to 90% Maximum altitude: 7000 ft (2133.6 m) Electrical input Input voltage: Low range: Minimum: 100 V ac Maximum: 127 V ac Input frequency range: 50-60 Hz Voltage switch setting: 115 V ac High range: Minimum: 200 V ac Maximum: 240V ac Input frequency range: 50-60 Hz Voltage switch setting: 230 V ac Input kilovolt-amperes (kVA) (approximate): Minimum configuration as shipped: 0.09 kVA Maximum configuration: 0.23 kVA Heat output (approximate) in British thermal units (Btu) per hour: Minimum configuration: 205.8 Btu/hr (60 watts) Acoustical noise-emission values Note: In this computer, fan speed is controlled by temperature, configuration, and software. Actual noise-emission values might be different from the stated values depending on the number of fans and the speed of the fans. Average sound-pressure levels for computers with a microprocessor that runs at or below 2.8 GHz: At operator position - 0.5 meters: Idle: 30 dBA Operating: 34 dBA At bystander position - 1 meter (3.3 ft): Idle: 26 dBA Operating: 29 dBA Declared (upper limit) sound-power levels: Idle: 4.0 bels Operating: 4.3 bels Average sound-pressure levels for computers with a microprocessor that runs at greater than 2.8 GHz: At operator position - 0.5 meters: Idle: 31 dBA Operating: 34 dBA At bystander position - 1 meter (3.3 ft): Idle: 26 dBA Operating: 29 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. Maximum configuration: 548.8 Btu/hr (160 watts) 6 User Guide
