Glossary 63
SCSI bus
Signal path or line shared by the devices on the same SCSI
channel. Information is often sent to all devices throughout the
same bus; only the device to which it is addressed will accept it.
slot
A slot is the place within the cartridge storage area, or the Mailbox
(Scalar 458 only), where the media is placed. Each slot has a
reference position, i.e. row 1, position 1 through position 12
(storage slots) and row 1, position 1 through 10 (Mailbox).
terminator
a physical block which tells the SCSI bus that this is the end of the
line. A terminator is required at both ends of a SCSI bus. A bus
may be terminated internally (on a device inside the host system)
or externally on a peripheral device.
unload
The process where the Scalar Library causes a drive to eject a
cartridge, then uses the Media Picker to move the cartridge to
either a storage slot location, or to a slot in the Mailbox.
