HP EML E-series Tape Libraries - Manual (Page 16)

Library robotics controller
The library robotics controller contains firmware to control the robot, communicate with the Interface
Manager card, manage the library servo and vision control, and monitor the door and load port
sensor status.
Robot commands are sent from hosts in the SAN to an interface controller, which directs them over
an internal Ethernet network to the library robotics controller. The library robotics controller translates
these commands into movements to be performed by the robot.

Interface Manager card
The Interface Manager card is an HP proprietary management card designed to consolidate and
simplify the management of multiple interface controllers installed in the library. It also provides
SAN-related diagnostics and management for library components, including the interface controllers,
tape drives, and robotics. The Interface Manager card, in conjunction with HP Command View TL
software, provides remote management of the library by using a serial, Telnet, or Web-based
graphical user interface (GUI).
