Note: For additional information about DIMMs, see
"Installing memory modules" on page 37.
1. Make sure that all the DIMMs in the blade server are
supported. Replace all the unsupported DIMMs.
2. Make sure that the DIMMs are installed in matched
pairs. If the DIMMs are not installed in matched pairs,
reinstall them in matched pairs.
3. Make sure that the DIMMs are correctly seated. If
necessary, reseat the DIMMs.
4. Restart the blade server.
5. Remove and reinstall the DIMMs one at a time until
the failing DIMM is isolated. Replace the defective
DIMM.
If the problem remains, replace the system-board
assembly. Contact a service support representative for
