If you received a POST error message or a IPMI Event LOG
, it can be caused by:
- One or more processors are not supported by the server.
- The processor configuration is not supported by the server.
- The server ROM is not current.
- A processor is not seated properly.
- A processor has failed.
You can try to take the following action:
- Be sure each processor is supported by the server and is installed as directed in the server documentation. The processor socket requires very specific installation steps and only supported processors should be installed.
- Be sure the BIOS is current.
- Be sure you are not mixing processor stepping, core speeds, or cache sizes if this is not supported on the server.
- If the server has only one processor installed, reseat the processor. If the issue is resolved after you restart the server, the processor was not installed properly.
- If the server has only one processor installed, replace it with a known functional processor. If the issue is resolved after you restart the server, the original processor failed.
- If the server has multiple processors installed, test each processor:
- Remove all but one processor from the server. Replace each with a processor terminator board or blank, if applicable to the server.
- Replace the remaining processor with a known functional processor. If the issue is resolved after you restart the server, a fault exists with one or more of the original processors. Install each processor one by one, restarting each time, to find the faulty processor or processors. At each step, be sure the server supports the processor configurations.
If you received a POST error message or an IML message which indicated an uncorrectable machine check exception
, please replace the processor.
