Specification

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

• Particulate contamination
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. For information about the limits for particulates and
gases, see "Particulate contamination" on page 10.
The server is designed for standard data center environment and is recommended to
be placed in industrial data center. Depending on hardware configurations, the server
complies with ASHRAE Class A2, A3, or A4 specifications with certain thermal
restrictions. System performance may be impacted when operating temperature is
outside permitted conditions.
The restrictions to ASHRAE support are as follows:
• The ambient temperature must be no more than 30°C if your server meets any of
the following conditions:
– 205 W < TDP ≤ 270 W
– Installed with any rear 2.5-inch NVMe drive
– Installed with any 256 GB DIMM or PMEM
– Installed with any passive GPU
• The ambient temperature must be no more than 35°C if your server meets any of
the following conditions:
– 165 W < TDP ≤ 205 W
– Installed with any front NVMe drive or rear NVMe AIC SSD
– Installed with any 7mm boot drive
– Installed with any M.2 NVMe drive
– Installed with any rear 2.5-inch SAS/SATA drive
• The ambient temperature must be no more than 45°C if the CPU TDP is equal to
or smaller than 165 W.
