Action
1. Make sure that the server contains DIMMs.
2. Reseat the DIMMs.
3. Install DIMMs in the correct sequence (see
"Installing a memory module" on page 89).
4. Clear CMOS memory to re-enable all the memory
connectors (see "System-board switches and

that are identified and replace it with an identical
pair of known good DIMMs, then restart the
server.
3. Return the removed DIMMs, one pair at a time, to
their original connectors, restarting the server after
each pair, until a pair fails. Replace the DIMMs in
the failed pair with identical known good DIMMs,
restarting the server after each DIMM is installed.
Replace the failed DIMM. Repeat this step until
you have tested all removed DIMMs.
4. (Trained service technician only) Replace the
system board.
