7. Clean — amber
On: cleaning cartridge in use
Off: the drive does not require cleaning
Flashing: the drive needs cleaning
8. Encryption — blue/amber
On (blue or amber): at power on
Off: drive is idle with no encryption key
Off with Ready LED flashing: drive is reading/writing
unencrypted data or loading/unloading a cartridge
On (blue): drive is idle with encryption key
On (blue) with Ready LED flashing: drive is reading/writing
encrypted data and some or all of the data on the cartridge
is encrypted
Blue and amber flashing alternately: encryption or
decryption error
NOTE:
Only the Ultrium LTO-5 and LTO-6 tape drives have
an encryption LED.
Using hardware encryption
Encryption protects data from unauthorized access
and use by changing it into a form that cannot be
read until it is deciphered with the encryption key.
LTO-4 and later generation tape drives include
hardware capable of encrypting data while writing,
and decrypting data when reading. Hardware
encryption can be used with or without compression
while maintaining the full speed and capacity of the
tape drive and media.
LTO tape drives use the 256-bit version of the
industry-standard AES encryption algorithm to
protect data.
IMPORTANT:
powerful feature and should be used with
care. If you need to import media onto
another machine or to recover after disaster
you will be required to enter the encryption
key used to write the tape. Neither you nor a
service engineer can recover a lost
encryption key. Without the key, an encrypted
tape is unreadable.
To use hardware encryption you need:
A backup application that supports hardware
encryption.
LTO-4 or later generation data cartridges; no
encryption will be performed when writing
LTO-3 and earlier generations of tape.
For additional information and requirements for
using hardware encryption, see the user guide.

Always use Hewlett Packard Enterprise storage
media to prolong the life of the tape drive. To learn

Caring for media
Many tape drive and backup failures are caused by
damaged or improperly handled tape cartridges.
Keep the cartridge in the case provided.
Store and transport cartridges in the vertical
orientation.
Follow the temperature, humidity, and
acclimatization guidelines on the cartridge
packaging.
Avoid dropping the cartridge or handling it
roughly because doing so is likely to damage
the cartridge.
Inspect cartridges regularly for damage.
Do not exceed the normal cartridge life.
