Troubleshooting
Interpreting Library LEDs
LEDs communicate status and errors as they are occurring. Use the
library LEDs to determine the state of the library.
All library cards and drive modules contain LEDs. In general, a yellow
LED comes on during power up and changes to green when power up is
successful. This may take a few minutes on some library cards.
The LED bar underneath the front panel display indicates library
activity.
