If a processor’s yellow LED is OFF and the red LEDs show an error code
in the range 1–45, the power-up self-test failed and the processor board is
bad. If the processor board has an attached vector processor and the error
code is 46–57, the vector processor board is bad. On the self-test console
display, the processor shows a minus sign (–) on the STF line.
After the power-up tests, each processor runs the CPU/memory interaction
tests and the multiprocessor tests. If a test fails, the processor shows
a minus sign (–) on the ETF line of the self-test console display. The
LED error codes are numbered from 61 to 82, which is the failing CPU/
memory test number (1 through 22) plus 60, or 91 to 97, which is the
failing multiprocessor test number (1 through 7) plus 90.
Each processor, after testing with the first memory, runs the CPU/memory
interaction tests on every other good memory module. (However, only CPU/
memory interaction test T0003 is run.) If a failure occurs, the memory
module is probably bad, althoughthe processor’s yellow light is OFF and the
memory module’s yellow light is ON. If several processors fail on the same
memory, that memory module is certainly bad. Try using SET MEMORY
to configure the bad module out of the interleave set. For error codes 83
through 89, consult Table B–1 to determine the failing memory.
The last series is the DWMBB tests. If one fails, the red LEDs contain an
error code, although the processor’s yellow self-test LED is ON (because
the CPU itself has passed). Note that only the boot processor performs the
DWMBB tests.
