The declared sound levels are based on the following configurations, which may change depending on
configurations/conditions, for example high-power processors and GPUs, and high-power network adapters
such as the Mellanox ConnectX-6 HDR/200GbE QSFP56 PCIe Adapters or the Broadcom 57454 10GBASE-
T 4-port OCP Ethernet Adapter.

Notes:
• These sound levels were measured in controlled acoustical environments according to procedures
specified by ISO7779 and are reported in accordance with ISO 9296.
• 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.
Particulate contamination
Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in
combination with other environmental factors such as humidity or temperature might pose a risk to the
device that is described in this document.
Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases
include damage that might cause the device to malfunction or cease functioning altogether. This
specification sets forth limits for particulates and gases that are intended to avoid such damage. The limits
must not be viewed or used as definitive limits, because numerous other factors, such as temperature or
moisture content of the air, can influence the impact of particulates or environmental corrosives and gaseous
contaminant transfer. In the absence of specific limits that are set forth in this document, you must
implement practices that maintain particulate and gas levels that are consistent with the protection of human
health and safety. If Lenovo determines that the levels of particulates or gases in your environment have
caused damage to the device, Lenovo may condition provision of repair or replacement of devices or parts
on implementation of appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.
