Hardware Operator's Guide Drives The cartridge is placed into the drive for data read or write operations. The LSM uses either DLT4000 or DLT7000 drives. From one to six drives can be installed, numbered 0 to 5, with 0 at the bottom. Note: Some software might number the drives from one to six. For specific drive information, refer to your drive publications. LSM Safety Features Safety features are incorporated into the LSM. If the front door to the LSM is opened, an electrical interlock removes power from the robot assembly. Behind the side door, covers are placed over certain assemblies to prevent you from coming into contact with the hazardous voltages and sensitive electronics. Do not open the side door-no operator activity is required behind this door. Controlling Software Controlling software, within the customer server, requests tape read/write operations to the drives and robotic move operations for the LSM robotic components. The software determines where the cartridge is located by tracking the VOLSER and cell location during audits, then allocates which drive receives the cartridge. For specific information, refer to your software publications. LSM Operating Modes An operating mode is the way in which an LSM and the controlling software (also referred to as the LSM management software) interact. An LSM can operate in either automated mode or manual mode, as described in the following subsections. Automated Mode Automated mode is the normal operating mode of the LSM. The controlling software instructs the robot to move the cartridge among the storage cells, drives, and CAP. The operator tasks include: S Monitoring the LSM operator display for messages S Entering a cartridge through the CAP S Ejecting a cartridge through the CAP S Replacing a cleaning cartridge Refer to Chapter 3 for the procedures. 1-6
