Policy Statement
Mellanox Technologies recognizes the importance of developing connectivity
solutions that not only enable our customers to optimize their data centers
performance, but also protect the environment and ensure that future generations
enjoy its bounties. Mellanox Technologies is committed, therefore, to meeting the
requirements of the European Union’s WEEE (waste electrical and electronic
equipment) directive. The directive mandates how the materials used in electrical
and electronic equipment must be disposed of.
Mellanox Technologies has worked closely with its suppliers to eliminate
hazardous materials from its products. There are instances, however, where it has
not proven possible to completely eliminate all hazardous materials.
Consequently, all applicable products are labeled with a crossed out “wheelie” bin
symbol, indicating that special care must be applied to their disposal and / or
recycling.
