IBM 847620U - Netfinity 3000 - 20U, Руководство по техническому обслуживанию аппаратной части, Страница: 64 / 270

Specifications (system)
The following table contains the environmental
specifications for the Netfinity 3000 server.
Notes
1. The following levels were measured in controlled
acoustical environments according to procedures
specified by the American National Standards
Institute (ANSI) S12.10 and ISO 7779, and are
reported in accordance with ISO 9296.
2. Actual sound-pressure levels in your location
might exceed the average values stated 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.

Depth: 445 mm (17.5 in.)
Ÿ
Width: 200 mm (7.9 in.)
Ÿ
Height: 492 mm (19.4 in.)
Weight
Ÿ
Maximum configuration (as shipped): 17.3 kg (38 lb)
Ÿ
Standard configuration (as shipped): 15 kg (33 lb)
Environment
Ÿ
Air temperature:
– System on: 10° to 35°C (50° to 95°F) at altitude 0–915 m (3000 ft)
10° to 32°C (50° to 90°F) at altitude 915–2134 m
(3000–7000 ft)
– System off: 10° to 43°C (50° to 110°F)
Ÿ
Humidity:
– System on: 8% to 80%
– System off: 8% to 80%
Heat Output
Ÿ
Approximate heat output in British thermal units (Btu) per hour:
– Maximum configuration (as shipped): 306 Btu/hour (90 watts)
– Maximum configuration (theoretical)1: 1564 Btu/hour (460 watts)
Electrical Input
Ÿ
Sine-wave input (50/60 Hz) is required
Ÿ
Input voltage:
–
Low range:
- Minimum: 90 V ac
- Maximum: 137 V ac
– High range:
- Minimum: 180 V ac
- Maximum: 265 V ac
– Input kilovolt-amperes (kVA) (approximately):
- Maximum (configuration as shipped): 0.70 kVA
Power consumption and heat output vary depending on the number and type
of optional features installed and the power-management optional features in
use.
Acoustical Noise-Emission Values
Ÿ
Average sound-pressure levels:
– At operator position:
- 35 dBA idle
- 40 dBA operating
1 Under typical maximum configurations, the heat output will be
substantially below the theoretical maximum.
