Table 1. Server specifications (continued)
Specification Description
Attention:
Airborne particulates and reactive gases acting alone or in
combination with other environmental factors such as humidity or temperature
might pose a risk to the server.
Your server complies with ASHRAE class A2 specifications. The server performance
might be impacted when the operating temperature is outside the ASHRAE A2
specifications. Server model with the following configurations complies with ASHRAE
class A3 and class A4 specifications:
• The processor TDP is 120/155 watts.
• There is no NVMe drive, rear drive cage, M.2 drive, GPU adapter, Ethernet adapter
of 10 GbE or higher, or PCIe NVMe adapter installed.
Note:
Server model with 2 port/4 port 1G OCP 3.0 Ethernet adapter installed can
comply with ASHRAE class A3 and class A4 specifications.
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.
