seconds per cycle. When the mechanical initialization is complete, the
Ready/Activity LED stops flashing and turns ON.
If a library failure occurs, the Ready/Activity LED turns OFF and the Error LED turns
ON. The Operator Panel also displays an appropriate error code to help identify the
failure.
The following are additional operational details of LEDs:
• The
Ready/Activity LED ( in Figure 2-1 on page 2-1) turns ON any time the unit
is powered ON and functional. The Ready/Activity LED flashes whenever there is
library or drive activity. This LED also flashes when the library is offline.
• The Clean Drive LED ( in Figure 2-1 on page 2-1) turns ON when a “cleaning
required” command is issued by the drive. The LED turns OFF after a successful
drive cleaning operation.
• The Attention LED ( in Figure 2-1 on page 2-1) turns ON to indicate that there is
a piece of media which is bad/marginal, or invalid. The LED turns OFF when all
marginal and invalid cartridges have been exported from the library. The Attention
LED also turns ON if Autoclean is enabled and no cleaning cartridge is in a
cleaning position.
• The Error LED ( in Figure 2-1 on page 2-1) turns ON when there is an
unrecoverable drive or library failure. An error message is displayed on the screen
and the LED remains ON until the error state is resolved.
