Cartridge Drives and Cabinets

■

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

•

Two or four 9490 (TimberLine) CTUs 

•

One to four SD-3 (RedWood) CTUs 

The 9741 or 9741E drive cabinets attach to the rear of the LSM and contains: 

•

One to ten Digital Linear Tape (DLT) drives 

•

One to ten T9840 Tape Drives 

•

One to ten T9940 Tape Drives 

Each CTU or tape drive holds the cartridge for read/write operations. For more 
specific information, refer to your CTU or tape drive publications. 

•

Only two of the three drive types that can be installed in a 9741 or 
9741E Drive Cabinet are allowed to be mixed in the same cabinet.

•

The T9940B drive cannot be installed in a 9740 LSM if the library uses a SCSI 
control path.

See 

 for more information about these drives.

■

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 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
