20 Chapter 3 Hardware TroubleshootingNN40160-700NN40160-700System status LEDsThe chassis of the BCM450 contains two LEDs: a Status LED and a Power LED. The Power LEDis located at the bottom left of the chassis; the Status LED is immediately above it. The tableSystem status LEDs states and descriptions on page 20 describes the meaning of the system statusLEDs in the following situations:• start-up sequence: LED indicators during the normal start-up process• safe-mode start-up sequence: LED indicators during a safe-mode start-up• shutdown sequence: LED indictors during a shutdown or failure• start-up profile sequence: LED indicators during an initial installation or stagingTable 1 System status LEDs states and descriptionsPower Status DescriptionStart-up sequenceSolid yellow Solid yellow Power applied to the system.Solid yellow Off Power on self test (POST); 9 seconds.Solid yellow Solid yellow System initialization; 14 seconds.Solid green Solid yellow Kernel initialization; 8 seconds.Solid green Flashing green Services initialization; 1 minute.Solid green Solid green System running; normal operation.Solid green Solid red Services initialization failureSafe mode start-up sequenceSolid red Solid green System running with manufacturing settings enabledSolid red Solid red System running in software reset modeSold red Flashing yellow System running in configuration reset modeShutdown sequence or failureSolid green Flashing yellow Shutdown in progressOff Solid yellow Shutdown completedSolid red Flashing yellow Overheating detected; thermal shutdown completedSolid red Solid red Power spike or rail power fluctuation detectedFlashing red Solid red Rail power fluctuation; power monitor shutdown completedSolid yellow Solid red Power spike shutdown completedOff Off No power; system is shut downStart-up profile sequenceFlashing yellow Flashing yellow Start-up profile executingFlashing green Flashing green Start-up profile completed (USB device can be removed)Solid green Solid green Start-up profile successfully appliedSolid green Solid red Start-up profile failure
