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
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.
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 Emissions
Declared Sound Power Levels
Idle: 4.0 bels
Operating: 4.3 bels
Average sound-pressure levels
At operator position - 0.5 meters (1.65 ft)
Idle: 29 dBA
Operating: 33 dBA
At bystander position - 1 meter (3.3 ft)
Idle: 25 dBA
Operating: 30 dBA
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.
