About Isolating Faults in the System
Each of the tools available for fault isolation discloses faults in different field–
replaceable units (FRUs). The row headings along the left of
TABLE 6-5 list the FRUs
in a Sun Fire V490 system. The available diagnostic tools are shown in column
headings across the top. A check mark (
✔ ) in this table indicates that a fault in a
particular FRU can be isolated by a particular diagnostic.
