Important notes

Processor speed indicates the internal clock speed of the microprocessor; other factors also affect
application performance.
CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible
maximum.
When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1 024 bytes,
MB stands for 1 048 576 bytes, and GB stands for 1 073 741 824 bytes.
When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000 bytes,
and GB stands for 1 000 000 000 bytes. Total user-accessible capacity can vary depending on operating
environments.
Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives
and population of all hard disk drive bays with the largest currently supported drives that are available
from Lenovo.
Maximum memory might require replacement of the standard memory with an optional memory module.
Lenovo makes no representations or warranties with respect to non-Lenovo products. Support (if any) for
the non-Lenovo products is provided by the third party, not Lenovo.
Some software might differ from its retail version (if available) and might not include user manuals or all
program functionality.

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
server 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 server 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 server, Lenovo may condition provision of repair
