Check Procedures 35
Start
This is the entry point for all check procedures. The
check procedures use failure symptoms, Power-On
Self Test (POST) error codes, or beeps to help
determine the defective field replaceable unit (FRU).
Follow the suggested check procedures or use the
diagnostics program from the service partition to
determine the problem FRU.
IMPORTANT:
Replace FRUs ONLY when it is
determined that the error is not a result of
software, loose contacts, or dirty component
surfaces. Any FRU change should be verified
by running a complete test (“Diagnostics - All
Tests” in PC-Doctor diagnostics program).
POST error codes and error messages are displayed
on the screen after the IBM logo. Meanwhile, error
beeps could be issued to help diagnose system
problem. Please refer to “Index of Symptoms,
Messages, Error Codes, or Beeps” on page 40 for
additional help.
All voltages in the check procedures are positive
unless otherwise indicated. Use frame ground for all
voltage checks unless otherwise specified.
NOTE:
If the check procedures instruct you to
replace a FRU and the error message persists,
an option adapter card might be causing the
failure. Remove all option adapter cards, one
at a time, until the error changes or the
problem is no longer apparent. Replace the
last option adapter card removed.
The hard disk drive contains pre-loaded software. Be
sure to reload the software on the primary hard disk
drive (Drive C) when replacing it.
IMPORTANT:
The drives in the system you are
servicing may have been rearranged, or the
drive startup sequence has changed. Be
extremely careful during write operations, such
as copying, saving, or formatting. Data or
programs can be overwritten if you select an
incorrect drive.
Ask the customer to back up
any additional software from the hard disk
drive before you reload the software.
