Glossary
ASC The Additional Sense Code is part of the SCSI-2 specification. The additional
sense code (ASC) field indicates further information related to the error or
exception condition reported in the sense key field.
ASCQ Additional Sense Code Qualifier is part of the SCSI-2 specification. The additional
sense code qualifier (ASCQ) indicates detailed information related to the
additional sense code.
Autoclean A user-defined mode made on the touch screen graphical user interface by which
the library automatically performs drive cleaning tasks.
Bit The basic unit of data in a binary numbering system (binary digit), represented
by a 0 or a 1. Eight bits equals one byte.
Byte The basic unit of computer memory which is large enough to hold one character.
Calibrate A process used by the library robotics to determine the exact position of storage,
data transfer, and import/export elements.
Check Condition
status This is part of the SCSI-2 specification. It is notification from the library back to
the host that the host needs to check the status of the library. It can indicate a
normal state change such as a door closed, or an error such as a move failure.
CISPR 22 This standard describes the emissions testing methods and test limits for
information technology equipment, such as computers, office machines, or
telecommunications equipment connected to low - voltage power main networks
(<600V). It does not apply to equipment whose primary function is radio
transmission or reception as defined by the International Telecommunications
Union (ITU) Radio Regulations. The object of the standard is to establish uniform
requirements for the conducted and radiated disturbance levels of the equipment
covered by the standard. Disturbance limits are established for Class A and Class
B equipment, and measurement methods, operating conditions, and interpretation
of results are addressed.
Class A digital
device Class A equipment is intended for Commercial installation.
Class I laser
product 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
product 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
