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 more operational details of LEDs:
v The Ready/Activity LED ( 6 in Figure 8 on page 13) turns ON any time the unit is powered ON and
functional. The Ready/Activity LED flashes whenever there is library. This LED also flashes when the
library is offline.
v The Clean Drive LED ( 7 in Figure 8 on page 13) turns ON when a "cleaning required" command is
issued by the drive. The LED turns OFF after a successful drive cleaning operation.
v The Attention LED ( 8 in Figure 8 on page 13) turns ON to indicate that a piece of media is
bad/marginal, or invalid. The LED turns OFF when all marginal and invalid cartridges are exported
from the library. The Attention LED also turns ON if Autoclean is enabled and no cleaning cartridge is
in a cleaning position.
v The Error LED ( 9 in Figure 8 on page 13) 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.
