Datasheet

Note:
(1) A solid Amber Clean LED indicates that the drive needs cleaning. In most cases the drive will continue to function, but
it should be cleaned as soon as possible.
(2) 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.
(3) 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:
z Hard SCSI Reset
z Cartridge Eject
z Power Cycle
z Retry Microcode Download
(4) The firmware download failed and the drive is not functional. The boot code is in control and the firmware download
should be tried again.
(5) The fault LED will be "ON" to indicate to indicate an over temp condition(internal temperature greater then a preset
allowable limit). The LED will remain on until the drive temperature drops below a preset limit and one of the following
conditions is met:
z A data or cleaning cartridge is inserted.
z A POR cycle occurs.
(6) The tape drive has exceeded its designed maximum internal operating temperature. The tape will be ejected, if present.
The Over Temperature/Fault LED will stay ON until the internal drive temperature goes below the preset maximum
temperature.
AIX will see the over temperature condition as if the tape drive went from ready to not ready. No error will be logged in the
AIX error log.
(7)While using drive diagnostics(via System Diagnostics or via the drive self test diagnostics), a flashing Clean LED
indicates that a media-related problem has occurred(such as a hard write error or excessive soft errors).
(8)While using drive diagnostics(via System Diagnostics or via the drive self test diagnostics) with media, the Activity and
Clean LED's will flash at the same time. The corrective action is to verify that your tape cartridge is not write-protected or
damaged, and that the media type is compatible with your tape drive.
