Isolating Failed Parts

C H A P T E R 10

The most important use of diagnostic tools is to isolate a failed hardware component so that a qualified service technician can quickly remove and replace it. Because servers are complex machines with many failure modes, there is no single diagnostic tool that can isolate all hardware faults under all conditions. However, Sun provides a variety of tools that can help you discern what component needs replacing.

This chapter guides you in choosing the best tools and describes how to use these tools to reveal a failed part in your Sun Fire V490 server. It also explains how to use the Locator LED to isolate a failed system in a large equipment room.
