System Function

Major system components include the following items:

• Host

•AMU

• Controllers

The basic operational philosophy of the AML/2 centers on the

host system which sends all commands to the rest of the

system.

When the host software determines that a specific media

library action is necessary, it creates the appropriate

command string and sends it to the AMU for processing. The

AMU receives and interprets the host command, and then

issues the appropriate command to the Robot and Storage

Segment Controller hardware.

After completing the movement actions, the Robot and

Storage Segment Controller Hardware return a status

message to the AMU. When all Controller status messages are

returned, the AMU reports the overall results to the host

system.

AML/2 Hardware Components

The main hardware components of the AML/2 library are:

•AMU

• Robot

• Storage Segments

• Control and Drive Cabinets

• Manual Insert/Eject (I/E) Facility

•Modem (optional)

A description of each of these components is found in the

following section.

AML Management Unit (AMU)

The AMU is the central interface of the AML/2 library,

connecting the host computer to the robot system and the

insert/eject unit. The AMU maintains a copy of the library

drives and media information in a relational database. During

normal operations, the host computer controls all functions of

the AML/2 library. The AMU hardware and software

components operate transparently.
