– 4.6 bels, typical
– 5.2 bels, maximum
• Sound power levels, operating
– 5.0 bels, minimum
– 5.1 bels, typical
– 5.5 bels, maximum
Notes:
• These sound power levels are measured in controlled acoustical environments
according to procedures specified by ISO 7779 and are reported in accordance
with ISO 9296.
• The declared acoustic noise levels are based on specified configurations and they
may change depending on configurations/conditions.
• The declared acoustic noise levels may increase greatly, if high-power
components are installed, for example, some high-power NICs, CPUs, and GPUs.
Electrical input
• Sine-wave input (50–60 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
Note:
For server models with 750-watt ac 80 PLUS Titanium power supplies, the
100–127 V ac input voltage is not supported.
CAUTION:
• 240 V dc input (input range: 180-300 V dc) is supported in Chinese Mainland
