IMPORTANT: Reboot the server after completing each numbered step. If the error condition
continues, proceed with the next step.
To troubleshoot processor-related error codes:
1. Bring the server to base configuration by removing all components that are not required by the
server to complete POST. This process can include removing all:
o Expansion boards ("Non-hot-plug expansion boards" on page 47)
o Processors ("Processor assembly" on page 34), except the processor installed in socket 1
IMPORTANT: Processor socket 1 and PPM slot 1 must be populated at all times or the server
does not function properly.
o PPMs ("PPM" on page 38), except the PPM installed in slot 1
o DIMMs ("FBDIMMs" on page 38), except the first bank
o Hard drives ("Hard drive" on page 31)
o Peripheral devices
2. Reseat the processor in socket 1.
3. Reseat the remaining processors, rebooting after each installation to identify any failed processors.
IMPORTANT: Populate the processors in the following order: 1, 2, 4, 3.
IMPORTANT: Always install a PPM when you install a processor. The system fails to boot if the
PPM is missing.
4. Replace the processor in socket 1.
5. Replace the processor board, if applicable.
6. Replace the system board.
IMPORTANT: If replacing the system board or clearing NVRAM, you must re-enter the server
serial number through RBSU ("Re-entering the server serial number and product ID" on page
