Acoustical noise emissions
Acoustical noise emissions
The server has the following acoustic noise emissions declaration:
• Sound power level (L
– Idling:
– Minimum: 4.0 bels
– Typical: 4.0 bels
– Maximum: 4.0 bels
– Operating:
– Minimum: 5.3 bels
– Typical: 5.8 bels
– Maximum: 5.8 bels
• Sound pressure level (L
– Idling:
– Minimum: 26.0 dBA
– Typical: 26.2 dBA
– Maximum: 26.2 dBA
– Operating:
– Minimum: 39.7 dBA
– Typical: 44.2 dBA
– Maximum: 44.2 dBA
Notes:
• These sound levels were 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 the following configurations, which may change depending on
configurations/conditions.
– Minimum: 1x 65W CPU, 2x 16GB RDIMMs, 1GbEx4 + 2.5GbE I/O module board, 1x NVMe M.2 boot drive, 2x
SATA SSDs, DC PMB, SE350 V2 Desktop mount.
– Typical: 1x 80W CPU, 4x 64GB RDIMMs, 25/10GbEx4 + 2.5GbE I/O module board, 2x NVMe M.2 boot drives, 4x
SATA SSDs, DC PMB, SE350 V2 Desktop mount.
– Maximum: 1x 100W CPU, 4x 64GB RDIMMs, 25/10GbEx4 + 2.5GbE I/O module board, 2x NVMe M.2 boot
drives, 4x SATA SSDs, DC PMB, SE350 V2 Desktop mount.
• 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.
