Environment:
• Air temperature:
– Server on: 10°C to 35°C (50°F to
95°F); altitude: 0 to 914.4 m
(3000 ft), decrease system
temperature by 1.0°C for every
1000-foot increase in altitude
– Server off: 5°C to 45°C (41°F to
113°F); maximum altitude: 3048
m (10000 ft)
– Shipment: -40°C to 60°C (-40°F
to 140°F); maximum altitude:
3048 m (10000 ft)
• Humidity:
– Server on: 20% to 80%;
maximum dew point: 21°C;
maximum rate of change: 5 °C/hr
– Server off: 8% to 80%; maximum
dew point: 27°C
• 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 541
.
