Statement of Volatility – Dell DX6112-SN
Dell DX6112-SN contains both volatile and non-volatile (NV) components. Volatile components lose their data
immediately upon removal of power from the component. Non-volatile components continue to retain their data
even after the pow er h as b ee n removed from the compo n en t. C omponents chosen as us er - de f i na bl e
configuration op t i ons (t h o s e no t so l de re d to t he m o t h er b o ar d) ar e n ot incl u d ed in t he St atement of Volatility.
Configuration option information (pertinent to options such as microprocessors, remote access controllers, and
storage controllers) is available by component separately. The following NV components are present in the
DX6112-SN system.
