Depth: 402 mm (15.82 in.)

Weight

Minimum configuration as shipped: 7.6 kg (16.8 lb)

Maximum configuration: 9.97 kg (22 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.

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: 0.30 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 0.68 cubic meters every minute (24

cubic feet every minute) maximum

Acoustical

noise-emission values

For microprocessors less than 2.8 GHz:

Average sound-pressure levels:

At operator position:

Idle: 28 dBA

Operating: 35 dBA

At bystander position - 1 meter (3.3 ft):

Idle: 25 dBA

Operating: 33 dBA

Declared (upper limit) sound-power levels:

Idle: 4.0 bels

Operating: 4.7 bels

For

microprocessors greater than or equal to 2.8 GHz:

Average sound-pressure levels:

At operator position:

Idle: 33 dBA

Operating: 35 dBA

At bystander position - 1 meter (3.3 ft):

Idle: 30 dBA

Operating: 33 dBA

Declared (upper limit) sound-power levels:

Idle: 4.4 bels

Operating: 4.7 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.
