Action/
Possible Failing FRU
1. Wait 10 minutes after the system has
reached the AIX prompt. Examine the AIX
error log for new B1xx 4633 errors with the
word 13 values (in bytes 68 and 69 in the
error log entry). If there are no B1xx 4633
errors with matching time stamps, the
SPCN down load was successful. If the
download failed again (there is another
B1xx 4633 error in the AIX error log with the
correct time stamp), do the following:
a. Power down the system.
b. Collect the service processor error log
data for the B1xx 4633 error (see 2 on
page 731).
c. Collect the SPCN trace data (see 3 on
page 731).
d. Contact service support. For all other
values of word 13, or bytes 68 and 69,
do the following:
1) Check for system firmware updates.
Apply if available.
2) Call service support.
1. Check SPCN cabling.
2. Go to "MAP 1542: I/O Problem Isolation" on
