Types 8149, 8177, and 8178

Dimensions

Height: 140 mm (5.5 in.)

Width: 425 mm (16.7 in.)

Depth: 425 mm (16.7 in)

Weight

Minimum configuration as shipped: 10.0 kg (22 lb)

Maximum configuration: 11.4 kg (25.0 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: 50/60 Hz

Voltage switch setting: 115 V ac

High range:

Minimum: 137 V ac

Maximum: 265 V ac

Input frequency: 50/60 Hz

Voltage switch setting: 230 V ac

Input kilovolt-amperes (kVA) (approximate):

Minimum configuration as shipped: 0.08 kVA

Maximum configuration: 0.3 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: 785 Btu/hr (230 watts)

Airflow

Approximately 0.51 cubic meters per minute (18 cubic

feet per minute) maximum

Acoustical

noise-emission values

Average sound-pressure levels:

At operator position:

Idle: 30 dBA

Operating: 32 dBA

At bystander position - 1 meter (3.3 ft):

Idle: 26 dBA

Operating: 30 dBA

Declared (upper limit) sound-power levels:

Idle: 4.0 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.
