Library Control Blade
1
The library control blade (LCB) manages the entire library, including the
operator panel and picker assembly, and is responsible for running
system tests to ensure that the library is functioning properly. The LCB
also provides internal communication to Fibre Channel (FC) I/O blade
slots. The LCB has four Ethernet ports, supporting a total of four FC I/O
blades in the library.
The LCB indicates its status with three LED Reliability, Availability, and
Serviceability (RAS) status indicators. These indicators are green, amber,
and blue in color.
•
Green
represents processor status.
•
Amber
represents health status.
•
Blue
represents power-control status.
