Hardware encryption and your Tandberg LTO-4
tape drive
Your Tandberg LTO-4 tape drive provides the ability to hardware encrypt your data,
applying the strongest level of AES industry-standard encryption and protecting the
data from unauthorized access and use. Encryption is supported only on Tandberg
LTO-4 1.6 TB media; media encrypted on a Tandberg LTO-4 drive can only be
read on a compatible Ultrium tape drive that supports hardware encryption.
Hardware encryption can be used with or without compression and without speed
or capacity penalties.
IMPORTANT:
Hardware encryption is a powerful feature, but should be used
with care. If you need to import your media onto another machine or to recover
after disaster you will be required to enter an encryption key.
• Hardware encryption is turned off by default and is switched on by settings in
your backup application, where you also generate and supply the encryption
key.
• Your backup application must support hardware encryption for it to work. The
software supplied with the tape drive provides this support. See
www.tandbergdata.com
for an up-to-date list of backup software.
• You should keep a record or backup of your encryption keys and store them in a
secure place separate from the computer running the backup software.
• If you are unable to supply the key when requested to do so, neither you nor
Tandberg Data Support will be able to access the encrypted data.

Understanding the LEDs
1 Clean
– amber
• On: cleaning cartridge in use
• Off: the drive does not require
cleaning
• Flashing: the drive needs cleaning
2 Tape
– amber
• Off: no fault has been detected
• Flashing: the cartridge currently in
the drive is faulty (damaged or
unsupported). Discard the cartridge.
3 Drive
– amber
• Off: no fault has been detected
• Flashing: the drive mechanism has
detected a hardware error
4 Ready
– green
• On: the drive is ready for use
• Off: the drive power is off or there
was a failure during self-test
• Flashing: the drive is busy

Choosing and looking after media
Your high-performance tape drive works best with high-performance Tandberg LTO
media. For optimum performance always use a data cartridge that matches the
specification of your tape drive (see table).
Table: Tandberg LTO data cartridge compatibility
* Capacity assumes 2:1 compression.
The recommended cleaning cartridge is the Tandberg LTO universal cleaning
cartridge. This cartridge is designed to work with any Ultrium drive and may be
used for up to 50 cleans.
It pays to look after your media
Many tape drive and backup failures are caused by damaged or badly handled
tape media.
• Keep media in the case provided.
• Follow the temperature, humidity and acclimitization guidelines on the media
packaging.
• Avoid dropping it or rough handling, as this is likely to damage the cartridge.
• Inspect it regularly for damage.
• Do not exceed normal cartridge life (260 full volume backup or restore operations).
