The Scalar Series models (Scalar 224, 448, 458) are SCSI-2 compliant library systems incorporating streaming
tape cartridge data storage devices which feature high capacity, high throughput, and data compression. Equipped
with four Digital Linear Tape (DLT) drives, your library operates as five independent SCSI devices on up to five
SCSI buses. Your library can contain up to 58 data cartridges providing a maximum formatted capacity of 4.06
TeraBytes and a sustained data transfer rate as high as 2400 MB per minute. The tape media is rated at 500,000
passes and has a shelf life of 30 years, providing superior media durability and data reliability.

Features
Media Interchange Shelf. When equipped, the Scalar Series 10-slot Media Interchange Shelf (Mailbox),
l
mounted on the transparent front door, allows you to insert and remove cartridges from your library without
opening the door. Access to each of the five-slot shelves is provided by a separate lockable door. The Mailbox
doors can be locked and unlocked by the application software.
Multi-function Operator Panel. The Operator Panel, located at the top-left of the front door, employs a 4-
l
line by 20-character liquid crystal display (LCD) and an eight-key keypad to permit you to monitor and
control the operations of your library.
Media Picker. The uniquely designed Media Picker is the media cartridge handling mechanism and normally
l
responds to commands from the application software to move the cartridges between the storage slots, the
drives, and the Mailbox. The Media Picker employs a bi-directional, pass-through gripper which will pick a
cartridge from both the front of the picker, or the back. This design eliminates the need for a separate
cartridge handling mechanism to pick and place cartridges from the Mailbox.
Barcode Scanner. The Scalar Series Barcode Scanner, mounted on the bottom of the Media Picker, reads
l
cartridge information contained in a barcode label attached to each of the data cartridges. This information
becomes part of the application software's library cartridge inventory.
Exabyte® Emulation. To maximize application software compatibility, your adic library provides
l
functional emulation of the Exabyte
™.
EXB-480
System Integrity. The cartridge slots, drives, and robotics are protected by a physically lockable door.
l
System security and media access is controlled by two lockable media interchange shelves. System security
can be enabled or disabled from the application software. Additionally, the Scalar Series Libraries feature a
logical lock system that can be set by the application software. The LOCKED LEDs on the Operator Panel
indicates that the system cannot be interrupted. Functions that would alter the state of the machine cannot be
accessed when the LOCKED LEDs are illuminated.
Maintainability. The full operation of your library can be viewed through the transparent panel that covers
l
the front door. If a problem occurs, it is both visible and readily correctable. Any condition that causes a
cartridge load or unload to fail is reported via a message on the Operator Panel LCD.
Cleaning Cartridge. Although the cleaning cartridge can occupy a cartridge storage slot in the Scalar Library
l
(facilitating automated cleaning cycles), manual insertion of a cleaning cartridge is permitted through the
Mailbox.
