Overview
adic
The
Scalar 218 design allows speedy fault isolation to the Field Replaceable Unit (FRU) level. Each
FRU can be rapidly replaced resulting in very short down-times for the customer.
The Scalar 218 is best thought of as three separate units: the library robotics section and each of the two
drives. The host computer views each of these units as separate SCSI devices.
The Scalar 218 is composed of the following functional sections:
Controller Section
l
Media Handling Mechanism
l
Drive Assembly Section
l
Power Supply Section

  • Page 5 This information is passed to the application software via the SCSI bus, which stores it in its cartridge inventory log. The barcode codes supported by the Scalar 218 are: Code 3 of 9 and Code 128. The Barcode Reader uses a Charge Coupled Device (CCD) sensor and a Light Emitting Diode (LED) light source.

  • Page 6: Operator Panel

    Media Picker. The Operator Panel interfaces to the Controller PCB. Cartridge Sensors Mounted beneath each of the 18 cartridge storage slots, the Cartridge Sensors monitor cartridge presence. The contents of the 218 (inventory) can quickly be determined by polling these sensors. Door Open Sensor The sliding access door open sensor alerts the Motion Processor of the door's position (opened or closed).
