Specifications This section lists the physical specifications for your computer. Dimensions Height: 89 mm (3.5 in.) Width: 276 mm (10.9 in.) Depth: 273 mm (10.7 in) Weight Minimum configuration as shipped: 6.3 kg (13.4 lb) Maximum configuration: 6.4 kg (14.1 lb) 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: 2134 m (7000 ft) Note: Since airline interiors are pressurized, this computer can operate on airplanes at altitudes above 2134 m (7000 ft). Electrical input Input voltage: Low range: Minimum: 100 V ac Maximum: 127 V ac Input frequency: 50/60 Hz High range: Minimum: 200 V ac Maximum: 240 V ac Input frequency: 50/60 Hz 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: 256 Btu/hr (75 watts) Maximum configuration: 682 Btu/hr (200 watts) Airflow Approximately 20 cubic feet (0.57 cubic meters) per minute Acoustical noise-emission values Average sound-pressure levels: At operator position: Idle: 26 dBA Operating: 34 dBA At bystander position - 1 meter (3.3 ft): Idle: 28 dBA Operating: 30 dBA Declared (upper limit) sound-power levels: Idle: 3.8 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. 42 Hardware Maintenance Manual

Specifications
This section lists the physical specifications for your computer.
Dimensions
Height: 89 mm (3.5 in.)
Width: 276 mm (10.9 in.)
Depth: 273 mm (10.7 in)
Weight
Minimum configuration as shipped: 6.3 kg (13.4 lb)
Maximum configuration: 6.4 kg (14.1 lb)
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: 2134 m (7000 ft)
Note:
Since airline interiors are pressurized, this
computer can operate on airplanes at altitudes
above 2134 m (7000 ft).
Electrical input
Input voltage:
Low range:
Minimum: 100 V ac
Maximum: 127 V ac
Input frequency: 50/60 Hz
High range:
Minimum: 200 V ac
Maximum: 240 V ac
Input frequency: 50/60 Hz
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: 256 Btu/hr (75 watts)
Maximum configuration: 682 Btu/hr (200 watts)
Airflow
Approximately 20 cubic feet (0.57 cubic meters) per
minute
Acoustical noise-emission values
Average sound-pressure levels:
At operator position:
Idle: 26 dBA
Operating: 34 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 28 dBA
Operating: 30 dBA
Declared (upper limit) sound-power levels:
Idle: 3.8 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.
