Specification
Important information about EU ecodesign requirements
To meet the EU ecodesign requirements for energy-related products (ErP) Lot 9, your server must meet the
following requirements:
• Minimum memory: 16 GB
• If your server is configured with one processor, these processors are not supported: Intel Xeon 3104,
3106, 3204, 4108, 4109T, 4110, 4112, 5122, 5222, 8156, and 8256.

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.
