Cartridge Subsystem
There are two designs for cartridge subsystems. One design covers the 4480
and 4490 product lines while a second design covers the 9490 and SD-3
product lines.
The 4480 or 4490 cartridge subsystem consists of one or two CDs within a
cabinet and one control unit (CU), each one in a separate cabinet. A CD can
have two or four transports, and it is cabled to the CU. The control unit is the
controller/interface between the CDs and the input/output (I/O) channels.
The 9490 or SD-3 cartridge subsystem consists of a cabinet containing
controller/transport units (CTUs). Each CTU has its own control unit that
interfaces with a single tape transport to perform read/write operations.
Refer to your cartridge subsystem publications for additional information.

can be attached to Panels 1 and 3 of the LSM.
