Error A DIMM configuration error has
occurred.
Info DIMM disabled
Error A sensor has changed to Critical
state from a less severe state.
Make sure that DIMMs are
installed in the correct sequence
and have the same size, type,
speed, and technology.
1. Make sure the DIMM is
installed correctly (see
"Installing a memory module"
on page 217).
2. If the DIMM was disabled
because of a memory fault
(memory uncorrectable error
or memory logging limit
reached), follow the
suggested actions for that
error event and restart the
server.
3. Check the IBM support
website for an applicable
retain tip or firmware update
that applies to this memory
event. If no memory fault is
recorded in the logs and no
DIMM connector error LED is
lit, you can re-enable the
DIMM through the Setup
utility or the Advanced
Settings Utility (ASU).
1. Make sure that the fans are
operating, that there are no
obstructions to the airflow,
that the air baffles are in
place and correctly installed,
and that the server cover is
installed and completely
closed.
2. If a fan has failed, complete
the action for a fan failure.
3. Replace DIMM n.
