Table 1. Server specifications (continued)
Specification
Description
Acoustical noise emissions
• Sound power levels, idle
– 4.5 bels, minimum
– 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
ONLY. Power supply with 240 V dc input cannot support hot plugging power
cord function. Before removing the power supply with dc input, please turn
off server or disconnect dc power sources at the breaker panel or by turning
off the power source. Then, remove the power cord.
• In order for the ThinkSystem products to operate error free in both a DC or
AC electrical environment, a TN-S earthing system which complies to 60364-
1 IEC 2005 standard has to be present or installed.
