ThinkSystem SR630 Maintenance Manual
Description
• 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, 100–
127 V ac input voltage is not supported.
CAUTION:
240 V dc input (input range: 180-300 V dc) is supported in China 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.
The server is supported in the following environment:
• Air temperature:
– Operating:
– ASHRAE class A2: 10–35°C (50–95°F); when the altitude exceeds 900 m
(2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F)
with every 300 m (984 ft) of altitude increase.
– ASHRAE class A3: 5–40°C (41–104°F); when the altitude exceeds 900 m
(2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F)
with every 175 m (574 ft) of altitude increase.
– ASHRAE class A4: 5–45°C (41–113°F); when the altitude exceeds 900 m
(2953 ft), the maximum ambient temperature value decreases by 1°C (1.8°F)
with every 125 m (410 ft) of altitude increase.
– Server off: 5–45°C (41–113°F)
– Shipping or storage: -40–60°C (-40–140°F)
• Maximum altitude: 3050 m (10 000 ft)
• Relative humidity (non-condensing):
– Operating:
– ASHRAE class A2: 8%–80%; maximum dew point: 21°C (70°F)
– ASHRAE class A3: 8%–85%; maximum dew point: 24°C (75°F)
– ASHRAE class A4: 8%–90%; maximum dew point: 24°C (75°F)
– Shipping or storage: 8%–90%
• 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 166.
Note: Your server complies with ASHRAE class A2 specifications. The server
performance might be impacted when the operating temperature is outside the
