Physical Inspection
Physical inspection of the system eliminates obvious
problems. Inspect the system before operating or changing
the system status, and before proceeding with other
troubleshooting measures.
Power-on Self-tests (POST)
This branch focuses on monitoring the power-on
capability of the system and the system's ability to pass
the initial self-tests.
Monitoring System Start-Up
The system start-up behavior focuses on the system's
ability to boot up after the self-tests. This branch
complements the system configuration branch by using
the system capabilities for configuration, expansion, and
total system test.
System Bus Configuration
The system must be properly configured according to
specific guidelines to ensure proper functioning. This
branch checks the backplane and card cage configuration.
Checking the Net
Monitoring network integrity uncovers faults in both the
physical and applications layers. Fault isolation in this
branch primarily focuses on the physical medium.
