Check Library and Component LED Indicators
When you have physical access to the library, you can monitor its overall status and
the status of individual Customer Replaceable Unit (CRU) components by checking
the indicators on the library base module. A pair of light-emitting diodes (LEDs)
shows the health of the library and the health of each of its customer-replaceable
components:
If the OK LED is green and the exclamation point LED is off, the library or
component is fully Operational.
If the OK LED is green and the exclamation point LED is amber, the library or
component is Degraded. It is still operating but with reduced functionality.
If the OK LED is off and the exclamation point LED is amber, the library or
component has Failed and cannot perform its function.
Library health indicators are located on the front panel of the library base unit at upper
left, alongside the power button. Health indicators for the customer-replaceable local
operator panel are found alongside the upper left corner of the touch-screen display.
The rear panel of the base unit also holds library health indicators. They are located at
the top of the rear panel just left of center. Additional indicators show the status of
customer replaceable units (CRUs), such as the robot/library controller, the power
supplies, and tape drives.
