Flash Memory Checksum Test (#86)
This test is a nondestructive test. The test computes the checksum of the
DEFINITY Generic 3 software and firmware loaded from the Software Memory
Card (SOFTWARE MEM-CARD). A failure of this test indicates corruption of the
Flash Memory. However, this failure does NOT always indicate a hardware
problem. DO NOT REPLACE the Processor circuit pack when this is the only
error. A system restart via the reset system 4 command starting with inserting
the Software Memory Card for this system followed by re-inserting the Translation
Memory Card memory card should be implemented at the customer’s earliest
convenience.
In a High or Critical Reliability system, an upgrade software command can be
used with the Software Memory Card for the system followed by re-inserting the
Translation Memory Cards as directed by this upgrade procedure. This
command performs the same operation as the reset system 4 command but is
much less service-disruptive.
1 - 7 FAIL If the system can still provide service, this indicates that the Processor
circuit pack has a problem with memory or the RISC processor, but can
still function.
At the customers convenience run the destructive “reset system 4”
command to boot the system and write to all of the memory locations.
This will clear transient parity errors and test for permanent parity errors.
This complete memory testing during initialization will cause “SPE
DOWN” if a parity error is detected and the PROCR circuit pack should
be replaced.
If parity errors reoccur within several weeks, record the error code
information indicating which memory modules failed, together with the
extended interval between failures. After recording the information and
at the customers convenience replace the PROCR circuit pack.
PASS The Memory is healthy.
