Specifications

This section lists the physical specifications for your computer.
Dimensions
Height: 492 mm (19.4 in.)
Width: 175 mm (6.9 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 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%
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: 240 V 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: 0.32 kVA
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.

Tools required

To install some options in your computer, you might need a flat-blade or Phillips
screwdriver. Additional tools might be needed for certain options. See the
instructions that come with the option.
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: 31 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: 4.2 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.
