Read All Memory Test (#85)
This test is a nondestructive test. The test reads every memor y location in
memory. A failure of this test indicates a DRAM failure in the Processor
circuit pack. DRAM is repl aceable and installed in 3 Single Inline Memory
Module (SIMM) sockets on this circ uit pack.
Flash Memory Checksum Test (#86)
This test is a nondestructive test. The test comp utes 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 shou ld be implemented at the customer’s earliest
convenience.

Test
Result Description/ Recommendation
100 ABORT The requested test did not complete within the allowable time period.
1. Retry the command.
2500 ABORT Internal system error
1. Retry the command.
1 - 7 FAIL If the system can still provide servic e, 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 rep laced.
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.
