The Autochanger Lists the First "Possibles"
At power on, and after every failed move, the autochanger automatically runs an
initialization sequence that comprehensively tests the autochanger. If a hard
failure occurs, a list of possible FRUs (Field Replaceable Units) that may have
been at fault is returned.
Figure 4–1 The Autochanger Returns Suspect FRUs
NOTE
This test sequence returns possible failed FRUs
only if there has been a hard failure. The test
sequence will NOT find an failure from which a
recovery was made.
Evaluating Results of the Internal FRU Isolation
Similar to treating symptoms rather than the real problem, the suspect FRUs
given by the FRU isolation procedure may actually mask the root cause of the
problem.
The hard move error that caused the autochanger to run the FRU isolation test
may have only been a PRODUCT of the actual problem. Blindly and repeatedly
replacing the suspect FRU(s) will not solve the problem.
