95°F) at altitude 0–2134 m (7000
ft)

Heat output 6
Ÿ
Approximate heat output in British
thermal units (Btu) per hour:
– Maximum configuration (as
shipped): 306 Btu/hour (90
watts)
– Maximum configuration
(theoretical) 5 : 1564 Btu/hour
(460 watts)
Electrical input 6
Ÿ
Sine-wave input (50/60 Hz) is
required
Ÿ
Input voltage:
– Low range:
- Minimum: 90 V ac
- Maximum: 137 V ac
– High range:
- Minimum: 180 V ac
- Maximum: 265 V ac
– Input kilovolt-amperes (kVA)
(approximately):
- Maximum (configuration as
shipped): 0.75 kVA
Acoustical noise-emission values 7
Ÿ
Average sound-pressure levels:
– At operator position:
- 37 dBA idle
- 42 dBA operating
– At bystander position–1 meter
(3.3 ft):
- 34 dBA idle
- 36 dBA operating
Ÿ
Declared (upper limit) sound power
levels:
– 5.0 bels idle
– 5.2 bels operating
5 Under typical maximum configurations, the heat output will be substantially below the theoretical maximum.
6 Power consumption and heat output vary depending on the number and type of optional features installed and the
power-management optional features in use.
7 These levels were measured 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.
