Acoustical noise emissions
• 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 sound levels may change depending on configuration/conditions, for example, with high-power NICs,
high-power processors and GPUs, such as ThinkSystem Mellanox ConnectX-6 HDR/200GbE QSFP56 1-port/2-
port PCIe Adapter, ThinkSystem Broadcom 57454 10GBASE-T 4-port OCP Ethernet Adapter.
• Government regulations (such as those prescribed by OSHA or European Community Directives) may govern noise
level exposure in the workplace and may apply to you and your server installation. The actual sound pressure levels
in your installation depend upon a variety of factors, including the number of racks in the installation; the size,
materials, and configuration of the room; the noise levels from other equipment; the room ambient temperature, and
employee's location in relation to the equipment. Further, compliance with such government regulations depends
on a variety of additional factors, including the duration of employees' exposure and whether employees wear
hearing protection. Lenovo recommends that you consult with qualified experts in this field to determine whether
you are in compliance with the applicable regulations.
Ambient temperature management
Ambient temperature management
The server is supported in the following environment:
• Air temperature:
– Operating:
– ASHRAE class H1: 5–25°C (41–77°F); when the altitude exceeds 900 m (2953 ft), the maximum ambient
temperature value decreases by 1°C (1.8°F) with every 500 m (1640 ft) of altitude increase.
– 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 H1: 8%–80%, maximum dew point: 17°C (62.6°F)
– 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)
– Shipment 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 14.
