Summary of the environmental specifications of server. Depending on the model, some features might not be available, or some specifications might not apply.

Acoustical noise emissions

Acoustical noise emissions
The server has the following acoustic noise emissions declaration: Sound power level (L_WAd) Idling: 7.3 Bel (Typical), 7.4 Bel (Max.) Operating 1: 7.3 Bel (Typical), 7.4 Bel (Max.) Operating 2: 8.3 Bel (Typical), 8.8 Bel (Max.) Sound pressure level (L_pAm): Idling: 57.1 dBA (Typical), 57.8 dBA (Max.) Operating 1: 57.1 dBA (Typical), 57.8 dBA (Max.) Operating 2: 66.4 dBA (Typical), 71.4 dBA (Max.) Note These sound levels were measured in controlled acoustical environments according to procedures specified by ISO7779 and are reported in accordance with ISO 9296. Idle mode is the steady state in which the server is powered on but not operating any intended function. Operating mode 1 is 50% of CPU TDP. Operating Mode 2 is 100% of CPU TDP. The declared acoustic sound levels are based on the below-specified configurations, which may change depending on configuration/conditions. (with four SD535 V3 nodes installed in the chassis) Typical: four 300-watt processors (9354P), forty-eight 64 GB RDIMMs, twenty-four SATA SSDs, four 25GB 2-port OCP modules, and two 2700-watt CRPS PSUs Maximum: four 400-watt processors (9554P), forty-eight 64 GB RDIMMs, eight NVMe SSDs, four 1GB 4-port OCP modules, four GPU adapters, and three 2700-watt CRPS PSUs 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
Adjust ambient temperature when specific components are installed. Note To avoid throttling, make sure to adopt passive Direct Attach cables when network adapters with 100GbE or higher speed are installed. If PCIe adapter with up to 2 ports is installed, the configuration only supports OCP module with up to 4 ports. If PCIe adapter with up to 4 ports is installed, the configuration only supports OCP module with up to 2 ports. The thermal rule is the same for Turin and Genoa processor with up to 300-watt TDP.
