Select Button

The Select button allows you to select any of the cartridges in the magazine. If

you press the button repeatedly, the number on the left of the front panel

display cycles through the cartridges available in the magazine. Press the Load

Cartridge button to load the selected cartridge.

Load Cartridge Button

Press the Load Cartridge button to load the selected cartridge from the

magazine into the drive and then put the autoloader into stacker mode. In

stacker mode, the loaded cartridge is used first; when it is full, or the host

computer sends an UNLOAD command, the autoloader replaces it with the

cartridge from the next highest numbered slot in the magazine. See Autoloader

Modes of Operation on page 3-8 for more information on stacker mode.

Eject Button

Press the Eject button to start the unload process. The drive unloads any

cartridge that is currently loaded, and the changer mechanism returns the

cartridge to the magazine. The magazine is then ejected.

You can also use the Eject button to force an ejection in an emergency. See

Forcing Ejection on page 3-7.

Note The host computer can disable the Eject button by issuing a SCSI PREVENT

MEDIA REMOVAL command.
