This chapter contains general information about the contents of this manual,
product descriptions, and other information useful when servicing the
product.
Diagnostic Information
The diagnostic information contains the check procedures you use to
diagnose and isolate product failures. Diagnostic information consists of:
Start:
This is the starting point for any diagnostic action. Based on
high-level symptoms, the information in this check procedure directs
you to more detailed procedures to help you resolve the machine
failure.
Symptoms, Messages, Error Codes, and Beeps:
The Index of Symptoms, Messages, Error Codes, or Beeps lists
symptoms and their probable causes, and directs you to the applicable
check procedures to help you resolve the machine failure. The index
also lists which FRU is the likely cause of the problem.
Check Procedures:
When the Start check procedure sends you to a specific check
procedure or the Index of Symptoms, Messages, Error Codes, or
Beeps, turn to that section and perform the steps as instructed. If
there are any notes or instructions at the top of the page, read them
before you start the procedure.
Carefully read each step of the check procedure and perform the
appropriate action as instructed. If you do not remember the location
of a specific part or test point, or if you do not remember an
adjustment or removal procedure, see the chapter with that
information. Always return to the check procedure after you do this.
In some cases, you are sent to other check procedures to find the
failure.
Diagnostic Aids:
The Diagnostic Aids chapter contains additional information to help
you diagnose a failure of a specific part.
