Memory Parity Error Detection Test (#87)
This test is a nondestructive test. The test is run on a few reserved locations in
memory. A failure of this test indicates a failure on the Processor circuit pack.
This test determines if the parity circuitry is working. Accordingly, the test
determines if parity errors can be detected. The parity circuitry is used to detect
DRAM memory failures.

1. Retry the command.
1 - 7 FAIL The parity detection circuitry is not working correctly. If the
system can still provide service, this indicates that the
Processor circuit pack has a problem but can still function.
1. The TN2404/TN790 Processor circuit pack should be
replaced. The failure is identifying the PROCR as being
bad and only the PROCR circuit pack needs to be
replaced. (Note that if you replace the Processor circuit
pack, you need to obtain a new license file.)
PASS The parity detection circuitry is working.
