Modes of Operation
Mount Message
When the CSL receives a mount message from the host, one of the following
occurs:
• If the drive is empty and the feed channel contains a cartridge which hasn’t
been previously loaded, the cartridge loads into the drive.
• If the drive and the feed channel are empty, but at least one cartridge is
available in the input bin, then the cartridge loads into the drive.
• Refer to “Priority Mount Mode” on page 5-20 to physically mount a priority
cartridge directly into the CSL.
Unload Message
When the CSL receives an unload message, the cartridge in the drive moves to
the feed channel. The CSL sequences as follows:
• If the output bin is not full, the cartridge is placed into the output bin.
• If the output bin is full, the cartridge remains in the feed channel, and the
operator indicator blinks until the cartridge is removed and the Start switch
is pressed.
Note: Refer to “Cartridge Removal from Feed Channel” on page 5-22 to
remove a priority mounted cartridge from the feed channel.
• If a mount has been pre-queued then, if possible, the next cartridge is
mounted with only one cartridge shift operation.
