Electrical input:
v Sine-wave input (50-60 Hz)
required
v Input voltage low range:
– Minimum: 100 V AC
– Maximum: 127 V AC
v Input voltage high range:
– Minimum: 200 V AC
– Maximum: 240 V AC
v Approximate input
kilovolt-amperes (kVA):
– Minimum: 0.60 kVA
– Maximum: 1.10 kVA
Notes:
1. Power consumption and heat
output vary depending on the
number and type of optional
features that are installed and
the power-management optional
features that are in use.
2. These levels were measured in
controlled acoustical
environments according to the
procedures that are 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 stated values 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.
Heat output:
Approximate heat output:
v Minimum configuration: 2013 Btu
per hour (590 watts)
v Maximum configuration: 3610 Btu
per hour (1058 watts)
Humidity:
v Server on: 20% to 80%, maximum
dew point 21°C, maximum rate of
change 5°C/hour
v Server off: 8% to 80%, maximum
dew point 27°C
