Test Description
Test Results
Memory Test:
Tests memory with
backup and data
cache disabled.
Test status displays on OCP:
12345.done.
If an error is detected, the bank number and failing
SIMM position are displayed. The following OCP message
indicates a failing SIMM at bank 0, SIMM position 2:
FAIL B:0 S:2
Test duration: Approximately 10 seconds per 8 megabytes
(MB) of memory.
Figure 2–2 shows the memory bank and SIMM layout for
the server processor. After determining the bad SIMM,
refer to Chapter 8 for instructions on replacing FRUs.
Note: The memory tests do not test the ECC SIMMs.
If the operating system logs five or more single-bit
correctable errors, swap the suspected ECC SIMMs with
good SIMMs and repeat the memory test.

indicates a failing SIMM at bank 0, SIMM position 2:
FAIL B:0 S:2
Test duration: Approximately 2 seconds per 8 (MB) of
memory.
Figure 2–2 shows the bank and SIMM layout for the
