LEDs communicate status and errors as they are occurring. Use the library LEDs
to determine how the library is functioning.
The front panel is the local control device for the library, and is located
on the front of the library. The LED bar beneath the front panel display indicates
library activity.
Green = library is ready and idle
Flashing Green = library or drive is active
Amber = library is partially available and idle
Flashing Amber = library failed

NOTE: The library could go into a partial availability
state due to a firmware mismatch. When this occurs, the front panel will
display Partly Available, and the illuminated LED beneath the front
panel will be solid amber. This is not an indication of a failure, but may
be an indication to download firmware.
Interpreting Library LEDs
LEDs communicate status and errors as they are occurring. Use the library LEDs
to determine 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 beneath the front panel display indicates library activity.

Amber
Library is partially available and
idle
Flashing Amber
