Physical specifications — small desktop model
Dimensions
Height: 104 mm (4.1 in.)
Width: 360 mm (14.2 in.)
Depth: 412 mm (16.2 in.)
Weight
Minimum configuration as shipped: 8.1 kg (18 lb)
Maximum configuration: 10.9 kg (24 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.

Heat output (approximate) in British thermal units (Btu)
per hour:
Minimum configuration: 257 Btu/hr (75 watts)
Maximum configuration: 686 Btu/hr (200 watts)
Airflow
Approximately 0.45 cubic meters every three minutes
(16 cubic feet every three minutes) maximum
Acoustical noise-emission values
Average sound-pressure levels:
At operator position:
Idle: 38 dBA
Operating: 43 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 33 dBA
Operating: 37 dBA
Declared (upper limit) sound-power levels:
Idle: 3.75 bels
Operating: 4.99 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.
Note: The computer is classified as a Class A or
Class B digital device. See the Quick Reference
for further information about this
classification.
