Lenovo System x3750 M4, Инструкция по установке и обслуживанию

Страница: 23 / 982

Note: The server is designed to the ASHRAE Class A3 guidelines
• 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%
• 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 949.
Airflow:
• Typical airflow: 55 CFM
• Maximum airflow: 100 CFM
Heat output:
Approximate heat output:
• Minimum configuration: 513 Btu per hour (150 watts)
• Maximum configuration: 4446 Btu per hour (1300 watts)
Electrical input:
• Sine-wave input (50 or 60 Hz) required
• Input voltage low range:
– Minimum: 100 V ac
– Maximum: 127 V ac
• Input voltage high range:
– Minimum: 200 V ac
– Maximum: 240 V ac
• 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.
Notes: Optional ML2 adapters that can be installed in this server are as follows:
• Intel I350-T4 ML2 Quad Port GbE Adapter for IBM System x
• Intel X540 ML2 Dual Port 10GbaseT Adapter for IBM System x
• Emulex VFA5 ML2 Dual Port 10GbE SFP+ Adapter for IBM System x
• Broadcom NetXtreme II ML2 Dual Port 10GbaseT for IBM System x
