1Summary of Diagnostic Tools, Post | Sun Microsystems V490 specification

The diagnostic tool spectrum also ranges from standalone software packages, to firmware-based power-on self-tests (POST), to hardware LEDs that tell you when the power supplies are operating.

Some diagnostic tools enable you to examine many computers from a single console, others do not. Some diagnostic tools stress the system by running tests in parallel, while other tools run sequential tests, enabling the machine to continue its normal functions. Some diagnostic tools function even when power is absent or the machine is out of commission, while others require the operating system to be up and running.

The full palette of tools discussed in this manual is summarized in TABLE 6-1.
