Statement of Volatility - Dell PowerEdge T20 CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. The Dell PowerEdge T20 contains both volatile and non-volatile (NV) components. Volatile components lose their data immediately after power is removed from the component. Non-volatile (NV) components continue to retain their data even after power is removed from the component. Components chosen as user-definable configuration options (those not soldered to the motherboard) are not included in the Statement 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 on the Dell PowerEdge T20 server. Table 1.

CAUTION:
A
CAUTION indicates either potential damage
to
hardware
or
loss
of
data and tells you how
to
avoid
the
problem.
The Dell PowerEdge T20 contains
both volatile and
non-volatile
(NV)
components. Volatile components
lose their
data
immediately
after power is
removed
from the
component. Non-volatile
(NV)
components continue
to retain their data
even
after power is
removed
from the
component.
Components chosen as user-definable configuration options (those not
soldered to the motherboard) are not included in the Statement 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 on the Dell PowerEdge T20 server
.
