Processor-related port 85 codes

Processor-related port 85 codes display in the format 3xh.

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:
   • Expansion boards
   • Processors, 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.

   • PPMs, except the PPM installed in slot 1
   • DIMMs, except the first bank
   • Hard drives
   • 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.
