Environmental specifications

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: 6.9 Bel (Typical), 7.4 Bel (Max.)
– Operating 1: 6.9 Bel (Typical), 7.4 Bel (Max.)
– Operating 2: 7.5 Bel (Typical), 8.3 Bel (Max.)
• Sound pressure level (L
– Idling: 51.2 dBA (Typical), 57.1 dBA (Max.)
– Operating 1: 51.2 dBA (Typical), 57.1 dBA (Max.)
– Operating 2: 57.1 dBA (Typical), 65.8 dBA (Max.)
Notes:
• 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 two SD550 V3 nodes installed in the chassis
– Typical: two 330-watt processors, sixteen 32 GB DIMMs, two GPU adapters, two 1GB OCP modules, and two
1300-watt CRPS PSUs
– Maximum: four 350-watt processors, thirty-two 64 GB DIMMs, twelve 2.5-inch drives, two 1GB OCP modules,
four GPU adapters, two CFF RAID 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.
