HP MSL6000 manual Robotics, Library Controller Board

Robotics

MSL Series tape library robotics consist of a cartridge shuttle, motor hardware, motor drives, and other support electronics (see Figure 5). The four-drive models also contain a vertical axis mechanism that enables the robotics to travel between the upper and lower tape cartridge magazines. These robotics are capable of picking and placing tapes throughout a 180-degree arc that consists of the tape drives, tape cartridge magazines, and an optional Pass-Through Mechanism (PTM).

The cartridge shuttle assembly includes a mounted bar code reader for scanning labeled tape cartridges installed in the magazines and tape drives.

NOTE: Both full bar code reader scan and physical scan are conducted each time the library is initially powered up, or each time a tape magazine is accessed using normal operational modes.

In four-drive models, the robotic-PTM interface is at the lower vertical axis PTM elevator position only.

Library Controller Board

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.

The library controller board is installed in a card cage at the rear of the library. In four-drive models, the library controller board can be serviced with a #1 Phillips screwdriver (see Figure 6). If a replacement controller board is needed, contact your authorized service provider. Step-by-step
