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 hasnt
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.
