This section contains information about how to troubleshoot DIMM problems.
In this section, the term “CPU module” or CMOD refers to a full CPU blade, including all CPUs and DIMMs on the blade. The term “CPU” refers to a single CPU.
Note - For information about Oracle’s DIMM replacement policy for x86 servers, contact your Oracle Service representative.
There are two ways to identify DIMM errors:
View the DIMM LEDs on the CPU modules (CMODs). See DIMM Fault LEDs.
View the ILOM System Event Log to view errors identified by the BIOS. See Identifying DIMM Error Messages .
See Correcting DIMM Errors for information on how to correct DIMM errors.
