How Autoloader Firmware Interacts
2.1.7.1 Interface Manager
The interface manager is responsible for handling all commands sent from a host
computer to the Autoloader. The commands are sent using a differential SCSI
interface, which conforms to the SCSI-2 specifications.
Note –
The interface manager is disabled when the product is in Stacker mode.
2.1.7.2 Front Panel Manager
The front panel is the user’s direct interface to the Autoloader. Most of the functions
that can be done through the SCSI interface can be accessed manually through the
front panel including full load/unload capability. See Section 3.5.2, “Autoloader
Display Menu Tree,” on page 3-12. The front panel interface is also described in
more detail in Chapter 3, “Product Operation and Configuration.”.
