1	Eject button
2	Ready (green)
3	Active (green)
4	Cleaning (amber)
5	Fault (orange)

The status lights and their ISO symbols are on the device as follows:

Ready ISO Ready symbol (green)

Activity ISO Active symbol (green)

Cleaning ISO Active symbol (amber)

Fault ISO Fault symbol (orange)

The combinations of the lights and their definitions are shown in the following table.

Note:

All 4 LEDs will be on solid for 2 seconds. A timing tolerance of 10 percent is acceptable.
If the drive completes Power-On Self-Test (POST) within 2 seconds, no POST in progress indication is required.
A solid amber Clean LED indicates that the drive needs cleaning. In most cases the drive will continue to function, but it must be cleaned as soon as possible.
If the cleaning function completes and the solid amber Clean LED remains lit, the cleaning function was not successful. The cleaning cartridge may be depleted. Obtain a new LTO cleaning cartridge and use it to perform the cleaning function again.
The Fault LED will flash to indicate an unrecoverable error. An unrecoverable error is an error condition that results in the drive not being able to function unless initiator, operator, or service intervention is applied. An unrecoverable drive failure is usually the result of a hardware error condition. One of the following actions will be needed to clear the flashing Fault LED:
- Hard SCSI Reset
- Cartridge Eject
- Power Cycle
- Retry Microcode Download
An unrecoverable cartridge (media) failure is usually the result of a defective cartridge, media, or cartridge state and will require the drive to eject the cartridge (if possible) to clear the flashing LED.
The firmware download failed and the drive is not functional. The drive boot code is in control and the firmware download must be retried.
When the Fault LED is solid, it indicates an over temperature condition. The drive has exceeded its preset temperature limit, and if a tape is present in the drive it will be ejected. The Fault LED will remain solid until the drive temperature drops below a secondary temperature limit, and a data or cleaning cartridge is inserted.
While running drive diagnostics (using either SEND DIAG or the Self-Test Procedure), a media-related problem (hard media error or excessive soft error rate) will be reported as a media failure (with flashing Clean LED), and a write-protected, damaged, or incompatible cartridge will be reported as incorrect media (with Activity and Clean LEDs flashing simultaneously).
