Tape Drives The library includes up to four Sony AIT tape drives, installed in the library on customized Spectra Logic drive sleds.

Tape Carousel Depending on the size ordered at time of purchase, the fixed tape carousel can store either 20 or 40 data cartridges when all four drives are installed. (When fewer than four drives are installed, the unused drive slots become additional tape cartridge slots.)

Robotic Picker The picker moves cartridges between tape slots, tape drives, and the library door. The picker may also include a bar code reader, which scans bar code labels on data cartridges.

Power Supply The power supply automatically detects the voltage and frequency of the power source, either 110-volt or 220-volt AC, 50/60 Hz. The power cord shipped with the library can handle either voltage.

UCM Board The UCM board is the library’s control center.

SDC Board Found only in HVD SCSI libraries, the single-ended to differential converter (SDC) board translates SCSI signals from single-ended to differential format.

Fibre Channel Board Found only in Fibre Channel libraries, this board translates SCSI signals to a flexible, high-speed Fibre Channel format.
