The system did not pass self-test. You will need a terminal to see the failed test. If POST is run in the diagnostic
B.1
mode, the failing board will loop on the error. The LED pattern should be frozen, except for memory tests.
Attach the terminal to the failing board and run POST for more details on the
failure. Retry the self-test that failed to make sure it is not an intermittent failure.
Run the diagnostic menu (see Section 3.6, "Running OBP and
POST" for instructions.) Examine the system status display.
If a board error, swap the system board, but retain the modules.
If a module error, follow Branch A.1 and swap out the module.
SIMM memory is checked during POST. The U-number and physical
B.2
address of the failed SIMM will be displayed on the terminal during POST.
Record the location number of the failed SIMM. Find the SIMM location in Figure 11-10
Remove and replace the SIMM. Ensure that the SIMM replaced is
of the correct value and is properly installed in the correct location.
