Tape drive status indicators

The tape drive LEDs show the following status:

●Tape LED (green) - The LED flashes to show activity (loading, unloading, reading, and writing). The LED is steady when a cartridge is loaded and the tape drive is ready to begin operation.

●Clean LED (amber) - The LED flashes to indicate that a cartridge is near the end of its life, or that the heads need cleaning.

The following table describes the LED combinations that occur during normal tape drive operation.

			Tape drive state
	Activity	Activity	Cartridge	Media	Fault	Power is
	(load or	(read or	loaded	caution		turned on
	unload)	write)		signal		(starts with
						two steady
						lights)
Tape LED	Flashing	Flashing	On	Any	Any	Flashing
(green)		Fast
Clean LED	Off	Off	Off	Flashing	On	Off
(amber)

The tape drive monitors the number of correctable errors that occur during reading and writing. If the number of errors becomes excessive, the tape may be nearing the end of its useful life, or the tape heads may need cleaning. The media caution signal reports the following:

●If the media caution signal displays (flashing amber), clean the tape drive.

●If the signal remains after cleaning the heads, repeat the operation with a different tape. If this clears the signal, the first tape is nearing the end of its life. Copy the data onto a new tape and discard the old one.

The media caution signal is cleared when a new tape is loaded or when the drive is turned off and then turned on.
