System reference code information
System reference codes (SRCs) are a sequence of data words (codes) that can help identify system status, describe a failure (for example, hardware, Licensed Internal Code, or software), and identify the failing unit and its location.
SRCs can display on the control panel, appear in a system console message, or appear in the product activity log. For details, see Product activity log. For details about how SRC information displays on the control panel, see SRC formats.
- The system gathers information about an error as the system detects the error.
- The product activity log (PAL) records and stores the error information.
- An SRC encodes information used to evaluate or identify a system-detected hardware or software error, failure, or status. The failure information may include the failing condition or part (or unit) that can be exchanged or replaced and its location.
- The SRC links to the problem determination procedure when the element detecting the failure cannot isolate the failing condition.
- The SRC link completes the isolation process.
In summary, the SRC provides the first-failure-data-capture information. The customer or support representative uses SRCs during problem determination, repair actions, and verification. The SRC provides a link to the problem determination procedures (hardcopy or softcopy). Use the SRC and the problem determination procedures to isolate the problem.
