Table 1. Specifications, Type 7Z59 and 7Z60 (continued)
Acoustical noise emissions The server has the following acoustic noise emissions declaration: 
•  Sound power level (LWAd) 
–  Idling:  
–  Typical: 6.1 Bel
–  Storage rich: 6.8 Bel
–  GPU: 7.4 Bel
–  Operating: 
–  Typical: 7.0 Bel
–  Storage rich: 7.5 Bel
–  GPU: 8.2 Bel
•  Sound pressure level (L
pAm): 
–  Idling: 
–  Typical: 47 dBA
–  Storage rich: 53 dBA
–  GPU: 60 dBA
–  Operating: 
–  Typical: 55 dBA
–  Storage: 61 dBA
–  GPU: 67 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 slightly depending on configuration/conditions.  
–  Typical configuration: four 165W processors, twenty-four 64 GB DIMMs, twenty- 
four SAS hard disk drives, 930-8i, Intel X710 10 GB 2 port, four 1100-watt power 
supply units
–  Storage rich configuration: four 205W processors, forty-eight 64 GB DIMMs, forty- 
eight SAS hard disk drives, 940-16i, Intel X710 10 GB 2 port, four 1100-watt power 
supply units
–  GPU configuration: four 205W processors, forty-eight 64 GB DIMMs, forty-eight 
SAS hard disk drives, 940-16i, Intel X710 10 GB 2 port, eight Nvidia Tesla T4, four 
1800-watt power supply units
•  The declared acoustic noise levels may increase greatly, if high-power components 
are installed such as high-power NICs, high-power processors and GPUs.
•  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.
