This section lists the physical specifications.
Dimensions
Height: 400 mm (15.7 in.)
Width: 175 mm (6.9 in.)
Depth: 432 mm (17.0 in.)
Weight
Minimum configuration: 8.17 kg (18 lb)
Maximum configuration: 10.21 kg (22.5 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.

Hardware Maintenance Manual
Heat output (approximate) in British thermal units (Btu)
per hour:
Minimum configuration: 246 Btu/hr (76 watts)
Maximum configuration: 785 Btu/hr (230 watts)
Airflow
Approximately 2.45 cubic meters (66 cubic feet per
minute) maximum
Acoustical noise-emission values
Average sound-pressure levels:
At operator position:
Idle: 31 dBA
Operating: 35 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 28 dBA
Operating: 32 dBA
Declared (upper limit) sound-power levels:
Idle: 4.1 bels
Operating: 4.4 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.
