1. Check the system-event log.
2. Check the DIMM error LEDs.
3. Remove the failing DIMM from the
system board (see "Removing a
memory module (DIMM)" on page
250).
4. Check for a server firmware update.
Important: Some cluster solutions
require specific code levels or
coordinated code updates. If the
device is part of a cluster solution,
verify that the latest level of code is
supported for the cluster solution
before you update the code.
5. Make sure that the installed DIMMs
are supported and configured
correctly (see "DIMM installation
sequence" on page 253 for more
information).
6. (Trained technician only) Replace
the system board (see "Removing
the system board" on page 290 and
"Installing the system board" on
page 292).
