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.
