Interpreting LEDs
Light emitting diodes (LEDs) provide a visual indication about the status of certain
library components. LEDs can sometimes communicate that a problem exists when
operator interventions cannot. For example, an LED can indicate a firmware
problem that prohibits the library from generating operator interventions.
The following components of the library have LEDs:
v “Power Button LEDs”
v “Library Control Blade LEDs” on page 9-7
v “Tape Drive LEDs” on page 9-8
v “Power Supply LEDs” on page 9-10
v “Picker LED” on page 9-11
Some of these components may also include a fibre port link LED.
Power Button LEDs
Two LEDs are located to the right of the library’s power button (
1
) on the front
panel of the control module.
v Green power ON LED (
2
) - When lit, this LED indicates that the library power
is ON.
v Amber Operator Intervention Alert LED (
3
) - When lit, this LED indicates that
there is a Library, Drives, or Media Operator Intervention available. To view the
Operator Intervention, select Tools → Operator Intervention from the Operator
Panel.
