Power-off the computer before removing or replacing parts.
4MB memory modules installed in slots 2 or 4 must be
FRU number 79F3234.
00011000 indicates a system board parity check error.
Remove all memory module kits except the one in
position 1. If the problem remains, replace the kit in
position 1. If the kit does not solve the problem,
replace the system board.
If the problem disappears after removing the memory
module kits (you should still have a kit in position 1),
install the kits, one at a time, until the problem
returns. Replace the kit that caused the problem to
return. If the kit 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 111 error. (If all of the adapters have been
removed and you still have a 111 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.
00021500, 00021600 indicates a failing system board
memory module kit.
If the error message does not indicate the location of
the failing kit, follow the procedure for a 00011000
error, described above.
