11.0 Memory
Note: Power-off the system before removing or replacing parts.
00011000 indicates a system board parity check error.
Replace the memory modules. If that does not solve the problem,
replace the system board.
00011100 indicates a memory expansion adapter parity check error.
Remove the memory expansion adapters from the expansion slots one at a
time until you no longer get a 00011100 error. (If all of the
adapters have been removed and you still have a 00011100 error,
replace the system board.)
Remove the memory expansion kits from the adapter that was removed
last. Install the kits one at a time until the failure returns.
Replace the kit that caused the error to return; if that does not
solve the problem, replace the adapter.
201 memory errors display as AAAAAA BBBB 201. Use the following figure to
