– Minimum: 90 V ac
– Maximum: 137 V ac
– Input frequency range: 57 – 63 Hz
– Voltage switch setting: 115 V ac
— High Range:
– Minimum: 180 V ac
– Maximum: 265 V ac

– Minimum configuration as shipped: 0.08 kVA
– Maximum configuration: 0.51 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 heat output in British thermal units (Btu) per hour:
— Minimum configuration: 256 Btu/hr (75 watts)
— Maximum configuration: 706 Btu/hr (207 watts)
Airflow
• Approximately 0.5 cubic meter per minute (18 cubic feet per minute)
Acoustical noise-emission values
• Average sound-pressure levels:
— At operator position:
– Idle: 33 dBA
– Operating: 40 dBA
— At bystander position-1 meter (3.3 ft):
– Idle: 4.4 bels
– Operating: 4.9 bels
Note: These levels were measures in controlled acoustical environments according
to 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 your 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.
