Interpreting Library Diagrams
Each component has a specific role that is critical in the library's overall
performance. Components serve either a logic (i.e., processes data) or interconnect
(i.e., carries signals between components) function within the library.
The following table lists the library components, their module location(s), and their
overall function (i.e., logic or interconnect):
Component Module Function

Library Control Blade (LCB)
The LCB1 is a critical logic component of the library. It is only located in the
control module. The LCB1 serves as the "brain" or primary control board, for
library operations. It communicates with the host server's backup application and
issues commands in communicating with various library components:
v Issues motion commands for the servo and motor driver board to execute over
the LCB1 to SMD1/SMD2 communication interface
v Library CAN network connects the LCB1 to the motion processor on SMD1
