HP EML E-series Tape Libraries - Manual (Page 129)

Glossary
array (1) A section of vertical or horizontal tape cartridge receptacles inside a library.
(2) A molded unit that holds multiple cartridges.
backplane The storage system electronic printed circuit board into which storage system
devices can be plugged.
bar code reader A component of the robot that is used for tape cartridge identification and
position calibration.
base module The 12U module in every HP Enterprise Modular Library E-Series that contains
the robot, tape drives, and card cage for controller cards. For slot numbering
purposes, the base module is divided into a base unit (8U) and tape drive
expansion module (4U).
card Also called printed wire assembly or printed circuit board.
cartridge The plastic housing around a cartridge tape. A plastic leader block is attached
to the tape for automatic threading when loaded in transport. The spine of the
cartridge contains a label listing the volume identification number.

center door A door on the center-front of a library through which service personnel or
operators can access the interior of the library.
Class A digital
device
Class A equipment is intended for commercial installation.
Class I laser prod-
uct
Class 1 lasers are products where the power of the laser beam produced (the
accessible emission) is always below the Maximum Permissible Exposure value.
Therefore, for Class 1 lasers the output power is below the level at which it is
believed eye damage will occur. Exposure to the beam of a Class 1 laser will
not result in eye injury. Class 1 lasers may therefore be considered eye safe.
Class II laser prod-
uct
Class 2 lasers are limited to a maximum output power of 1 mW. A person
receiving an eye exposure from a Class 2 laser, either accidentally or as a result
of someone else’s deliberate action (misuse) will be protected from injury by
their natural blink reflex. This is a natural involuntary response which causes the
individual to blink and avert their head thereby terminating the eye exposure.
cleaning cartridge A tape cartridge that contains special material to clean the tape path in a
transport or tape drive. LTO cleaning cartridges labels have CLN prefixes.
CLI Command Line Interface
CompactPCI (cPCI) Industry standard bus used for card-to-card bus expansion.
containment box A box in the HP Enterprise Modular Library robot that holds the lift-flex cable.
The cable retracts into the box as the table is raised.
data cartridge A term used to distinguish a cartridge onto which a tape drive may write data
from a cartridge used for cleaning purposes.
drive The device that the library uses to record data onto tapes. Also called tape drive.
drive cleaning A library feature that uses a cleaning cartridge to clean a tape drive.
