L’etiquette du système respecte la Directive européenne 2002/96/EC en matière de
Déchets des Equipements Electriques et Electroniques (DEEE), qui détermine les
dispositions de retour et de recyclage applicables aux systèmes utilisés à travers
l’Union européenne. Conformément à la directive, ladite étiquette précise que le
produit sur lequel elle est apposée ne doit pas être jeté mais être récupéré en fin
de vie.

In accordance with the European WEEE Directive, electrical and electronic
equipment (EEE) is to be collected separately and to be reused, recycled, or
recovered at end of life. Users of EEE with the WEEE marking per Annex IV of the
WEEE Directive, as shown above, must not dispose of end of life EEE as unsorted
municipal waste, but use the collection framework available to customers for the
return, recycling, and recovery of WEEE. Customer participation is important to
minimize any potential effects of EEE on the environment and human health due to
the potential presence of hazardous substances in EEE. For proper collection and
treatment, contact your local Lenovo representative.

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 or replacement of servers or parts on implementation of
appropriate remedial measures to mitigate such environmental contamination.
Implementation of such remedial measures is a customer responsibility.
