Cartridge Drives and Cabinets
The cartridge drive attaches to the rear of the LSM and contains:

LSM Safety Features
Safety features are incorporated into the LSM. If the front doors to the LSM are
opened, electrical interlocks remove power from the robot assembly.
Behind the right front door, covers are placed over the library controller card
and the LSM power supply to prevent contact with the hazardous voltages and
sensitive electronics.
■
Controlling Software
Controlling software is the interface between the host operating system and the
LSM. The software determines where the cartridge is located by tracking the
VOLSER and cell location during audits, then allocates which CTU or drive
receives the cartridge.
If the LSM goes offline for any reason, you can mount and dismount cartridges
manually, as described in
