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 this test fails, a minus sign (–) shows for the processor on the self-test
console display 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 console display. The LED error codes
are numbered from 51 to 65, which is the failing CPU/memory test number
(1 through 15) plus 50, or 81 to 87, which is the failing multiprocessor test
number (1 through 7) plus 80.
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, although the 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
1
to configure the bad module out of the interleave set. For error codes 70
through 76, consult Table B–1 to determine the failing memory.
If the DWMBB/A yellow LED is off, the module has failed self-test, The
yellow LED of the KA66A will be on, and the KA66A red LEDs give the
number of the failing DWMBB test, as shown in Table B–2.

command.
