xviii Scalar AIT 440/480
Cartridge handling mechanism (CHM)
The cartridge handling mechanism (CHM) moves cartridges between
cartridge slots, tape drives, and the entry/exit port.
Bar code scanner
The high-speed bar code scanner, mounted on the CHM, reads bar code
labels affixed to the cartridges to track individual cartridges. Cartridge
label information becomes part of the library's cartridge inventory stored
in nonvolatile RAM.
Entry/exit transport assembly
The entry/exit transport assembly moves the transport arm to and from
the entry/exit port to pick up cartridges.
Serial ports
Two serial ports (25-pin and 9-pin) at the back of the library allow you
to communicate with the tape drives and the library across a serial cable
connected to an external computer. By running a special diagnostic
program, you can perform diagnostics, upgrade firmware, and test CHM
motion.
