(blinking

normal).
Check Point (CP) Codes
Codes beginning with “CP” are displayed on the LCD to
indicate system status during POST. The CP codes vary
with the level of microcode installed and the type of
processor card installed. The CP codes are not error
codes. If the system detects an error, the CP code is
changed to a POST error message.
System Error Log
The computer system maintains a system error log. The
BIOS nonmaskable interrupt (NMI) handler writes an entry
to the error log each time the system detects an error.
Viewing the error log:
To view the error log, start the
system programs and select More utilities from the Main
Menu, then select Display system error log. For any
error that is displayed, help screens guide you through the
actions to take.
Error Storage:
The error log stores up to three
unique
errors (for example three parity errors at three different
addresses). The multiple log counter (on the screen)
displays the number of times each unique error occurred.
You can page forward by pressing F8, or backward by
pressing F7 to view the stored error logs. The date and
time of the most recent occurrence also is displayed. If
the POST finds that the error log has stored three unique
errors, the POST displays a 000179XX error.
Note: If the system configuration is changed, the system
clears any logged errors associated with the FRU
that was changed. (For example, if the memory
configuration was changed, memory errors are
cleared from the error log). The conditions under
which errors are cleared vary with the type of
hardware and level of microcode installed.
Application:
If the system diagnostics run error-free,
but you still suspect a problem, look at the error log. If
errors were detected, press the F1 key and follow the
