Lenovo 3633 Installation And Service Manual page 21

• Width:
– Without Electronic Industries Association (EIA) brackets: 434.6 mm (17.11 inches)
– With EIA brackets: 482 mm (18.98 inches)
• Maximum weight: 13.8 kg (30.36 lb)
Acoustical noise emissions:
Sound power: 5.4 bels for both idle and operating environment
In the idle environment, the server is only running the operating system. In the operating environment,
the microprocessor is active and the TDP is occupied 50%.
The noise emission level stated is the declared upper limit sound power level, in bels, for a random
sample of machines. All measurements are made in accordance with ISO 7779 and reported in
conformance with ISO 9296.
Environment:
• Air temperature:
– Server on:
– Server models with a lower-than-55 W CPU:
5°C to 40°C (41.0°F to 104.0°F); altitude: 0 m to 950 m (0 ft to 3117 ft)
The maximum system temperature decreases by 1°C (1.8°F) with every 175 m (574 ft) increase
in altitude above 950 m.
– Server models with a higher-than-55 W CPU:
10°C to 35°C (50.0°F to 95.0°F); altitude: 0 m to 950 m (0 ft to 3117 ft)
The maximum system temperature decreases by 1°C (1.8°F) with every 175 m (574 ft) increase
in altitude above 950 m.
– Server off: 5°C to 43°C (41°F to 109.4°F)
– Shipping: -40°C to 60°C (-40°F to 140°F)
• Maximum altitude: 3050 m (10000 ft)
• Humidity:
– Server on: 8% to 85%; maximum dew point: 24°C (75.2°F); maximum rate of change: 5°C (9°F)/
hour
– Server off: 8% to 85%; maximum dew point: 27°C (80.6°F)
• Particulate contamination:
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
When the operating temperature enhancement kit is installed, the temperature response for the fan
speed control is more accurate.
Heat output:
• Minimum configuration: 143 BTU per hour (42 watts)
• Maximum configuration: 710 BTU per hour (208 watts)
Electrical input:
• Sine-wave input (50 Hz to 60 Hz) required
• Input voltage low range:
