Fail Card Test Detail, Fail CPU RAM Test IC26

Failure of the CPU/Memory CP at power-up generates the following type of error message:

FAIL: <CARD>: <TEST>: <DETAIL>:

The bracketed fields contain the following information:

●<CARD> is CPU/Memory

●<TEST> is one of the following:

RAM TEST

ROM TEST

AAINTERFACE DUART TEST REAL-TIME-CLOCK TEST B U S E R R O R

WORK CYCLE D P R T E S T MMU TEST

AA RESET STUCK : SC?

●<DETAIL> specifies the specific location of the failure, such as the address of a failed integrated circuit.

A representative Common Control failure message would be as follows:

This message identifies the failure as a Random Access Memory (RAM) test failure in integrated circuit 26 occurring on the CPU/Memory CP.

After partial failure, the system continues to operate and the green LED on the CPU/Memory CP flashes normally.
