Acoustical noise emissions
The server has the following acoustic noise emissions declaration:
• Sound power level (L
WAd
– Idling:
– GPU Typical: 7.8 Bel
– GPU Max: 8.0 Bel
– Operating:
– GPU Typical: 8.4 Bel
– GPU Max: 8.6 Bel
• Sound pressure level (L
– Idling:
– GPU Typical: 62.5 dBA
– GPU Max: 63.2 dBA
– Operating:
– GPU Typical: 68.3 dBA
– GPU Max: 71.3 dBA
Notes:
• These sound levels were measured in controlled acoustical environments according to procedures specified by
ISO7779 and are reported in accordance with ISO 9296.
• The declared acoustic sound levels are based on the specified configurations, which may change depending on
configuration/conditions.
– GPU Typical: two 360W processors, four or eight NVIDIA A100 80 GB GPU adapters, twelve 32 GB RDIMMs
(2Rx8), two 2.5-inch NVMe SSDs or two E1.S 5.9mm NVMe SSDs, one ThinkSystem Broadcom 57504 10/25GbE
SFP28 4-Port OCP Ethernet Adapter, one 1P NDR (NVIDIA ConnectX-7 card)
– GPU Max: two 360W processors, four NVIDIA H100 80 GB GPU adapters, twenty-four 128 GB 3DS RDIMMs,
eight 2.5-inch NVMe SSDs or six E1.S 5.9mm NVMe SSDs, one ThinkSystem Broadcom 57508 100GbE QSFP56
2-Port OCP Ethernet Adapter, six 1P NDR (NVIDIA ConnectX-7 card)
• 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
Adjust ambient temperature when specific components are installed:
• Keep ambient temperature to 30°C or lower when one or more of the following components are installed.
– NVIDIA H100/H800 PCIe GPU adapter
– NVIDIA ConnectX-7 dual-port NDR200 or single-port NDR400 with Active Optical Cable installed in the PCIe slot
15, 16, 20, or 21
