When this happens, the drive can experience excessive errors while reading or writing, and during operations, the LTO-4-120 displays the letter "C" on the
seven-segment display and illuminates the amber status LED and the LED dot.
This means that the drive needs to be cleaned.
The LTO cleaning cartridge has the same dimensions as the tape cartridge and contains an LTO Cartridge Memory (LTO-CM), but is loaded with cleaning media
instead of recording media. Always keep the LTO cleaning cartridge in its protective case when not in use.
Procedure
To clean the Dell PowerVault LTO-4-120 Half-Height tape drive:
1. Load an LTO cleaning cartridge into the tape drive.
2. Observe that during the cleaning process, the drive displays the letter "C" on the seven-segment LED and both the LED dot and the green status LED
are flashing.
3. After the cleaning process completes, depending on the drive configuration, either:
¡ The drive automatically ejects the LTO cleaning cartridge, or
¡ If you must press the Eject button to eject the LTO cleaning cartridge, then the LTO cleaning cartridge has expired. Please mark the LTO cleaning
cartridge as expired and discard.
4. Write the date on the cartridge label for future reference.
Each time you use the LTO cleaning cartridge, the cleaning media advances to a new, unused section. After approximately 50 cleanings, all of the media will be
used up. The Dell PowerVault LTO-4-120 drive displays the number "7" on the seven-segment LED, turns off the LED dot, flashes the amber status LED, and
holds the LTO cleaning cartridge in the drive.
Always discard used-up LTO cleaning cartridges.
Performing an Emergency Cartridge Eject
If the Dell PowerVault LTO-4-120 Half-Height tape drive stops communicating with the host computer, use this emergency procedure to eject the cartridge (if
necessary).
To perform an emergency cartridge eject, hold down the Eject button 10 seconds or more, and release it. The tape drive firmware will then ignore all
outstanding commands and eject the cartridge.

NOTE: If the Dell PowerVault LTO-4-120 Half-Height tape drive does not recognize the cartridge as an LTO cleaning cartridge, the drive stops the
cleaning process and ejects the cartridge.
NOTE: If the clean indication reappears and remains on continuously within 24 hours after a cleaning cycle, perform the cleaning procedure again. If,
after three cleaning cycles in a 72-hour period, the clean indication comes on again, contact your Technical Support organization.
CAUTION: When you perform an emergency cartridge eject, any data in the drive or host buffers will not be written to the tape and the tape
record may not be correctly terminated with an end-of-data mark. If the end-of- data mark is not written to the tape, you will not be able to
append any data to that tape unless you overwrite the existing data on the tape.
