130 Interpreting Library LEDs

Chapter 4

Interpreting Library LEDs

LEDs communicate status and errors as they are occurring. Use the library 

LEDs to get an indication of how the library is functioning.
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.
