7-2 Section 7-1 - Overview
7-1-2 Diagnostic Procedure Summary
Although Diagnostics can be run in any order, the Bottom-up Confidence-Building Order outlined in this
section:
- Provides a framework from which overall diagnostic testability can be discussed.
- Provides a top-level model that describes the confidence-building aspect of the diagnostics.
- Provides a logical step-by-step approach to system check-out and fault isolation.
There are two levels of diagnostic: board-level and system level.
- Board-level diagnostics are intended to test functionality of a single circuit board.
- System-level diagnostics are intended to test functionary on more than one circuit board.
Unused system components (board or signals) for each diagnostic test are drawn in gray (ghosted).
NOTE: In this document, the Host includes all hardware upstream of the PCI cable. The diagnostics in this
chapter do NOT test anything upstream of the PCI cable. Therefore, any upstream hardware or software
must be functional before running these diagnostics.
