  • Page 40: Normal Mode

    If the system passes all the POSTs, all four LEDs light again and then go off. Next, the OBP firmware performs its initialization sequence and the system banner appears on the screen. A generic SPARCstation banner is shown as an example. From this point on, the keyboard LEDs assume their normal functions (that is, you should no longer interpret the LEDs as diagnostic error indicators).

    POST Error Messages POST error messages returned to the terminal are self-explanatory. For example, if no DSIMM is installed in the system, the POST will tell you that no DSIMM is installed and will indicate the slot number of the DSIMM slot. Use the error messages returned by POST to troubleshoot the system.
  • Page 45 Note – The Caps Lock key LED on some U.S. keyboards, located just above the left- hand Shift key, is not used as a POST failure indicator, but blinks on and off while POST is running. If the Caps Lock key fails to flash on and off after you have pressed and held the Stop-d keys when you power on the system, POST failed.
