The library controller board contains a single microprocessor and associated logic devices to control all robotics operations and manage overall library functions. The microprocessor enables the SCSI interface between the library and the host system, including Web TLC (Total Library Control).
Web TLC is built into the library controller board. Web TLC enables you to remotely monitor and control the tape library from any terminal on a local network or access the internet. For more information on Web TLC, see Chapter 8, “Web TLC” on page 63.
Robotics
The library contains robotics which consist of a cartridge shuttle, motor hardware, motor drives, and other support electronics. The robotics can pick up and place tapes throughout a 180° arc that consists of the tape drives, tape cartridge magazines, and an optional cartridge elevator.
The cartridge shuttle assembly includes a mounted bar code reader for scanning tape cartridges installed in the magazines and tape drives as shown in Figure 9 on page 8.
A full bar code reader scan and a physical scan are conducted each time the library is powered up or a tape magazine is exchanged.
