Specification Description
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, 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.
Environment 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.
Note: Your server complies with ASHRAE class A2 specifications. The server performance might
be impacted when the operating temperature is outside the ASHRAE A2 specifications. Depending
on the hardware configuration, some server models comply with ASHRAE class A3 and class A4
specifications. To comply with ASHRAE class A3 and class A4 specifications, the server models
must meet the following hardware configuration requirements at the same time:
