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 For air cooled node: 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. The following processors require a 25°C ambient temperature, and has limited drive and adapter support: ThinkSystem AMD EPYC 9274F 24C 320W 4.05GHz Processor ThinkSystem AMD EPYC 9374F 32C 320W 3.85GHz Processor ThinkSystem AMD EPYC 9474F 48C 360W 3.6GHz Processor ThinkSystem AMD EPYC 9475F 48C 400W 3.65GHz Processor ThinkSystem AMD EPYC 9375F 32C 320W 3.8GHz Processor The following processors are supported at a 25°C ambient temperature with limited drive and adapter support, however processor performance may be impacted: ThinkSystem AMD EPYC 9184X 16C 320W 3.55GHz Processor ThinkSystem AMD EPYC 9384X 32C 320W 3.1GHz Processor ThinkSystem AMD EPYC 9275F 24C 320W 4.1GHz Processor ThinkSystem AMD EPYC 9175F 16C 320W 4.2GHz Processor For water cooled node: 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 2 ports. If PCIe adapter with up to 4 ports is installed, the configuration does not support OCP module. If OCP module with up to 4 ports is installed, the configuration does not support PCIe adapter.

Water requirements

Water requirements
Attention The water required to initially fill the system side cooling loop must be reasonably clean, bacteria-free water (<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water. The water must be filtered with an in-line 50 micron filter (approximately 288 mesh). The water must be treated with anti-biological and anti-corrosion measures. Environment quality must be maintain over the lifetime of the system to receive warranty and support on affecting components. For more information please see Lenovo Neptune Direct Water-Cooling Standards. Water temperature: ASHRAE class W45: up to 45°C (113°F) inlet temperature to the rack Maximum pressure: 0.21 bars per node Minimum water flow rate: 1 liter per minute per node Note The water required to initially fill the system side cooling loop must be reasonably clean, bacteria-free water (<100 CFU/ml) such as de-mineralized water, reverse osmosis water, de-ionized water, or distilled water.
