System x3750 M4 Types 8722 and 8733: Installation and Service Guide
Environment:
v Air temperature:
– Server on: 5° to 40°C (41° to
104°F); altitude: 0 to 3048 m
(10,000 ft) derate maximum dry
bulb temperature 1°C (33°F) per
175 m (574 ft) above 950 m
(3,117 ft). Maximum rate of
change 20°C (68°F) per hour.
– Server off: 5° to 45°C (41° to
113`°F)
– Shipment: -40°C to +60°C (-40°F
to 140°F
Note: The server is designed to the
ASHRAE Class A3 guidelines.
v Humidity range (noncondensing):
– Server on: Minimum = higher
(more moisture) of -12°C (10°F)
dew point and 8% to 85%
relative humidity; maximum
dew point: 24°C (75°F)
– Server off: 8% to 85% relative
humidity; maximum dew point:
27°C (80°F)
– Shipment: 5% to 100%
v Particulate contamination
Attention: Airborne particulates
and reactive gases acting alone or
in combination with other
environmental factors such as
humidity or temperature might
pose a risk to the server. For
information about the limits for
particulates and gases, see
"Particulate contamination" on
page 663.
Airflow:
v Ideal airflow: 35 cubic feet per
minute (CFM)
v Typical airflow: 50 CFM
v Maximum airflow: 160 CFM
Heat output:
Approximate heat output:
v Minimum configuration: 95 Btu per
hour (28 watts)
v Maximum configuration: 6580 Btu
per hour (1928 watts)
Electrical input:
v Sine-wave input (50 or 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 Input kilovolt-amperes (kVA),
approximately:
– Minimum: 0.030 kVA (system
off)
– Maximum: 1.856 kVA
Notes:
1. Power consumption and heat
output vary depending on the
number and type of optional
features installed and the
power-management optional
features in use.
2. The sound 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 noise emission level
stated in the declared (upper
limit) sound-power level, in bels,
for a random sample of system.
