Procedures
Procedure 1 – Board Assembly Part Number identification:
To determine the Board Assembly Part Number and Revision, refer to the label applied to the rear surface of yourproduct. The Assembly Part Number should be formatted as “P/N: 132028a-01L” where “a” is the letter revision ofthe assembly (e.g. A, B, C…).

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 isnot 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 sameinterface available to the user; typically applied through the standard read and write commands to the storagedevice.
Sanitization:
Per NIST Special Publication 800-88 Revision 1, “sanitization” is a process to render access to “Target Data” on themedia infeasible for a given level of effort. In this document, clearing is the degree of sanitization described.
