Advanced Diagnostic Routines
The Advanced Diagnostic Routines options allow the service
technician to perform tests on the system unit that require special
action such as installing wrap plugs or keying certain responses.
The
Problem Isolation Charts (PICs)
use the Advanced
Diagnostic Routines to perform the additional tests and repair
checkouts.
The Advanced Diagnostic Routines run more extensive tests on the
adapters that can be tested with wrap plugs than the Diagnostic
Routines. If the configuration record on the fixed disk does not
match the installed features list, the program displays the TEST
OPTION or the DIAGNOSTIC TEST LIST menu.
When an option is listed in the configuration record, but is not
sensed by the Loadable POST programs, the TEST OPTION menu
displays. This menu indicates that either the option has been
removed from the system, the option is failing, the switch settings
have been changed, or the option has been moved
to
another slot.
When the Loadable POST programs sense an option that is not in
the configuration record, the DIAGNOSTIC TEST LIST menu
displays. This menu indicates an option has been added
to
the
system. When an option is deleted from the DIAGNOSTIC TEST
LIST menu, that option is not tested until added
to
the list using
the Show and Change Diagnostic Test List Utility.
To run the Advanced Diagnostic Routines:
1. Press Enter after reading the DIAGNOSTIC OPERATING
INSTRUCTIONS.
2. Choose Advanced Diagnostic Routines on the FUNCTION
SELECTION menu.
3. Choose a checkout option on the ADVANCED DIAGNOSTIC
SELECTION menu. An
*
(asterisk) by the ID number shows
that the test has been run.
