Encryption Status LED
Encryption-capable drives have a tri-color, encryption-status LED on the rear panel, see
TABLE 1-1 on page 26
for an explanation of the status indications. Drive trays that fully
enclose the drive usea light pipe to transfer the LED indication to the rear of the tray
(see the
CRYPT
label in the figure below).
If the encryption status LED is green, it indicates that the drive is encryption capable,
but not encryption enabled. In this state, the drive functions only in a non-encryption
safe mode, and cannot read/write encrypted data cartridges. However, the drive can
function normally for non-encryption tasks.
Once the drive is encryption enabled, the LED turns red to indicate that the drive is
armed and functioning in the encryption mode. In this state, the drive can read/write
encrypted data cartridges. The drive can also read non-encrypted data cartridges, but
cannot write to non-encrypted data cartridges.
