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 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.
