Sun Fire[tm] 12K / 15K / E20K / E25K LEDs

Hardware Indicators

The LED indicators provide current status information about the component directly associated with the indicator array. Indicators are arranged in a straight line, horizontal or vertical, with the green LED on the left or top.

Sun Fire 12K / 15K E20K / E25K LEDs
Symbol	LED Color	Indication	Operation
	Green	Activation indicator	Component is powered on.
	Amber	Service indicator	Service indicator is only used during initial startup.
	Amber or Blue	Removal indicator	Component may be removed.

Component LED Status

Click on the Component links for LED locations and more information.

Failure of the service LED to transition from ON to OFF within 60 seconds after insertion indicates a power-status control fault (except for CPU Board and Power Supply LEDs).

Note: When servicing an adapter in an hsPCI cassette in an F15K system under SMS 1.1, do not rely on the status LEDs on the hsPCI cassette. Instead use the output from the "showboards" command to determine if an hsPCI cassette is currently in a state where it may be safely removed from the hsPCI assembly (See FIN I0802 for complete details) .

Centerplane Support Board

System Control Board

The System Control (SC) CPU slot and SC 6U/3U spare slot on the SC board do not have unique bits, referred to as presence bits.

System Control CPU Board Indicator Function Descriptions
Indicator Functions	Description
Alarm	Not used.
Ready	Component ON and board is READY.
Reset button	Global reset to the SC CPU and PCI reset to the SC. When the RESET button on the front panel of the SC CPU (CP1500 or CP2140) board is pressed, a Power-on-reset (POR) is generated to the SC CPU board and a peripheral component interconnect (PCI) reset is generated to the PCI devices on the SC main board. This results in a general clearing of the SC CPU board to a power on state, and a reset of the PCI bus on the SC main board. Using the RESET button will reboot the operating system on the SC if the appropriate open boot PROM environment variables have been set.
Abort button	Resets the CPU. When the ABORT button on the front panel of the SC CPU (CP1500 or CP2140) board is pressed, an external initiated reset (XIR) is generated to the CPU module, returning the CPU to a known start up state. No other devices are affected by this reset.

CAUTION: Using the SC CPU reset and SC CPU abort hardware buttons may corrupt the operating system disk if the operating system has not been properly shut down.

System Control Peripheral Board

System Control must be present and powered on before the SC peripheral board can be powered on.

System Control DVD Peripheral Indicator Function Descriptions
Indicator Functions	Description
Blinking (.8 second intervals)	Busy
OFF	Idle
OFF	No disk
ON	Error
Blinking (1.6 second intervals)	Audio playback
ON	Data transfer

System Control Tape Peripheral Indicator Function Descriptions
Indicator Functions		Description
Tape Indicator	Green flashing and amber OFF	Loading or unloading
	Green fast flashing and amber OFF	Reading and writing
	Green ON and amber OFF	Tape is loaded and ready
	Green ON or OFF and amber flashing	Clean tape drive
	Green ON or OFF and amber ON	Error
Cleaning Mode	Green fast flashing and amber OFF	Cleaning in progress
Firmware Upgrade Mode	Green fast flashing and amber fast flashing	Firmware is downloading (auto ejection when complete)
