Table 2-1 Summary of Available Diagnostic Tool

When or why to use
Executes automatically at power-on. The POST code resides in
the boot PROM and is driven by the Por signal from the power
supply. POST tells you if the major hardware components of
the main logic board, the frame buffer, and the hard disk fails.
Described later in this chapter.
Test such as the Ethernet test, and the diskette drive controller
test are available. You must be in the Forth Toolkit to run
on-board diagnostics. Enter n from the > prompt to enter the
Forth Toolkit. The On-Board diagnostics reside in the boot
PROM. Described later in this chapter.
Runs under SunOS. It displays real-time use of the system
resources and peripherals. The Sundiag System Exerciser tells
you if your system is functioning correctly or not. If Sundiag
fails, run the Power-On Self-Test. If all power-on self-tests
pass, then run the SunDiagnostic Executive to identify the
problem. See the Sundiag User's Guide for more information.
Runs extensive, configurable subsystem tests independent of
SunOS. Run the SunDiagnostic Executive if all tests pass when
you run POST. Running the SunDiagnostic Executive allows
you to troubleshoot which field replaceable unit needs to be
replaced. See the latest version of SunDiagnostic Executive
User's Guide for the SPARCstations for more information.
Enters the Monitor when the operating system crashes. To
bot SunOS or another program from the > prompt, enter b. To
resume execution of a halted program from the > prompt,
enter c. To enter the Forth Toolkit from the > prompt, enter n.
Described later in this chapter.
Performs all functions available through the Monitor, except
entering the Forth Toolkit. Changing NVRAM parameters.
Resetting the system. Running diagnostics. Displaying system
information. Redirecting input and output. See the Open
