Description
• Sine-wave input (50 Hz to 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
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:
• Two power supplies installed
• NVMe drives not installed
• PCIe flash adapter not installed
• GPU not installed
• Certain processors not installed:
– Processors with TDP more than or equal to 150 watts not installed
– For server models with twenty-four 2.5-inch drives or twelve 3.5-inch drives,
the following frequency optimized processors not installed: Intel Xeon 4112,
5122, 6126, 6128, 6132, 6134, 6134M, and 8156 processors
