Types 8185, 8186, 8192, 8413, and 8430
This section lists the physical specifications for the computer.
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: 9.1 kg (20 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: 90 V ac
Maximum: 180 V ac
Input frequency range: 47–53 Hz
Voltage switch setting: 115 V ac
High range:
Minimum: 137 V ac
Maximum: 265 V ac
Input frequency range: 57–63 Hz
Voltage switch setting: 230 V ac
Input kilovolt-amperes (kVA) (approximate):
Minimum configuration as shipped: 0.08 kVA
Maximum configuration: 0.25 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: 257 Btu/hr (75 watts)
Maximum configuration: 683 Btu/hr (200 watts)
Airflow
Approximately 0.45 cubic meters per minute (16 cubic feet
per minute) maximum
Acoustical noise-emission values
For microprocessors less than 2.8 GHz:
Average sound-pressure levels:
At operator position:
Idle: 28 dBA
Operating: 30 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 27 dBA
Operating: 29 dBA
Declared (upper limit) sound-power levels:
Idle: 4.2 bels
Operating: 4.3 bels
For microprocessors greater than or equal to 2.8 GHz:
Average sound-pressure levels:
At operator position:
Idle: 29 dBA
Operating: 31 dBA
At bystander position - 1 meter (3.3 ft):
Idle: 28 dBA
Operating: 29 dBA
Declared (upper limit) sound-power levels:
Idle: 4.3 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.
