3490 Tape Subsystem Controls for Model F1A

The 3490E Model F1A drive unit operator panel „1… is accessible to the operator by opening the front of the frame containing the tape subsystem to be accessed.

When 3490E subsystems are attached to the 3494, the following 3490E functions change:

Drive control

The loading and the unloading of volumes are controlled by the library manager. The 3490E subsystem communicates with the library manager to update the database with the drive status and the cartridge location information.

Message displays

The library manager controls which messages are displayed to prevent the messages from getting out of synchronization with the library manager during Manual mode operations.

Attention interrupt

The library manager can use the communication path to the 3490E subsystems to send information to the host.
