   If	Then
   Yes:	Continue with the next step.
   No:	No service action is required. This ends the procedure.

      • If your system is an 8001-12C or 8005-12N, go to 8001-12C or 8005-12N locations to identify the physical location and the removal and replacement procedure.
      • If your system is an 8001-22C or 8005-22N, go to 8001-22C or 8005-22N locations to identify the physical location and the removal and replacement procedure.
   This ends the procedure.
