Procedures
Procedure 1 -Board Assembly Part Number Identification:
To determine the Board Assembly Part Number and Revision, refer to the label
applied to the surface of your product. The Assembly Part Number should be
formatted as “P/N: ######A-##L
Terms and Definitions
Cycle Power:
The process of completely removing power from the device and its components
and allowing for adequate discharge. This process includes a complete shutdown
of the PC and/or chassis containing the device; a reboot is not sufficient for
the completion of this process.
Volatile Memory:
Requires power to maintain the stored information. When power is removed from
this memory, its contents are lost. This type of memory typically contains
application specific data such as capture waveforms.
Non-Volatile Memory:
Power is not required to maintain the stored information. Device retains its
contents when power is removed. This type of memory typically contains
information necessary to boot, configure, or calibrate the product or may
include device power up states.
User Accessible:
The component is read and/or write addressable such that a user can store
arbitrary information to the component from the host using a publicly
distributed NI tool, such as a Driver API, the System Configuration API, or
MAX.
System Accessible:
The component is read and/or write addressable from the host without the need
to physically alter the product.
Clearing:
Per NIST Special Publication 800-88 Revision 1, “clearing” is a logical
technique to sanitize data in all User Accessible storage locations for
protection against simple non-invasive data recovery techniques using the same
interface available to the user; typically applied through the standard read
and write commands to the storage device.
Sanitization:
Per NIST Special Publication 800-88 Revision 1, “sanitization” is a process to
render access to “Target Data” on the media infeasible for a given level of
effort. In this document, clearing is the degree of sanitization described.
