Modes of Operation
5-18 Sixth Edition 95741
Automatic Mode
The automatic mode allows the CSL to operate without operator intervention.
Cartridges automatically loads from the input bin into the drive. Cartridges are
loaded in the order they were inserted and unloaded into the output bin when
the operating system is finished with the tape.
Note: If the input bin is empty while the CSL is in Automatic mode, the
input bin must be replenished, and the Start switch must be pressed
to restart the CSL operation.
Refer to “Priority Mount Mode” on page 5-20 to physically mount a
priority cartridge directly into the CSL.
Unload Message
Upon receiving an unload message from the host, the CSL acts identically to the
unload in the system mode with a subsequent pre-queued mount of the next
cartridge into the drive automatically if possible. 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 from the output bin
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.
Example
A job requires a specific order of cartridges to execute.
1. Load the cartridge tapes into the input bin in the order they will be used.
2. Press the Start switch.
Note: The CSL automatically inserts cartridges into the feed channel in the
order they were inserted in the input bin and ejects them into the
output bin when the operating system has finished with each tape.
Place CSL in Automatic Mode
1. Press the Autoload Mode switch until the green automatic indicator
illuminates.
2. Press the Start switch to set the Automatic mode.
3. Load up to seven cartridges in the input bin in the required sequence (left
to right, in the order they will be used).
