Expansion board-related port 85 codes

Expansion board-related port 85 codes display in the format 6xh.

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

To troubleshoot expansion board-related error codes:

Reseat all expansion boards.
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 the expansion boards one at a time, rebooting between each installation to isolate the failed expansion board.
Replace the failed expansion board, if applicable.
Replace the PCI riser board, if applicable.
Replace the system board.

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