38 Operation and Maintenance
Using the Mailbox (Scalar 458 only)
On-Line Mode
When the Scalar Library is in On-Line Mode the application software is in control and directs all library
operations. The application software can use the Mailbox to insert or remove individual cartridges to/from the
drives, or to/from the cartridge storage shelves. Follow closely the instructions the application software provides
on your host computer system monitor.
The design of the Mailbox includes access control doors and cartridge stops in each of the media slots. The doors
are unlocked, except when the library is performing a media transport operation (pick and place). The cartridge
stops are solenoid controlled and prevent incorrect insertion of the media. The stops are held in the raised position
whenever the Mailbox access doors are unlocked. During library pick and place operations the stops are lowered,
allowing the library to insert or remove cartridges from the slots using the Media Picker.
Warning
The Mailbox access control doors are locked when the application
software performs a media transport operation (pick and place), or, the
application can lock the access control doors at any time. You cannot
open either door during this operation without severely damaging the
Scalar 458. Wait until your application software instructs you to open
either of these doors.
Loading a Cartridge into Scalar 458 Library
p Open the appropriate Mailbox access control door as instructed.
p Place the cartridge into the appropriate slot of the Mailbox with the write-protect switch at the top and the
barcode label facing you. Slide the cartridge in until the stop will not allow it to go any farther.
Note
The cartridge is inserted with the write-protect switch at the top and the
barcode label facing you. However, the cartridge stops will prevent you
from installing the media incorrectly.
p Close the Mailbox access control door.
p Follow any additional instructions provided by the application software.
The application software will now perform the intended operation with the cartridge.
Unloading a Cartridge from Scalar 458 Library
The application software will cause the cartridge to be ejected from the drive and will issue the pick and place
commands to have the library move the cartridge to a Mailbox slot.
p Open the appropriate access control door and remove the cartridge from the Mailbox.
p Close the access control door.
