Miscellaneous port 85 codes

To troubleshoot all other port 85 codes:

IMPORTANT: Reboot the server after completing each numbered step. If the error condition continues, proceed with the next step.

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
Install each remaining system component, rebooting between each installation to isolate any failed components.
Clear the system NVRAM.
Replace the system board.

IMPORTANT: If replacing the system board or clearing NVRAM, you must re-enter the server serial number through RBSU.
