cleaning cartridge A tape cartridge that
contains special material to clean the tape
path in a transport or drive.
CLI Command line interface.
CompactPCI (cPCI®) Industry standard
bus used for card-to-card bus expansion.
controller The module that houses the
controls for the elevators, CAPs, turntables,
and service safety door.
cPCI See CompactPCI.
customer interface module (CIM) The
front module of the SL8500 library at which
the customer has access to the touch screen
operator panel and CAPs, and service
personnel have access to the library and
service bay.
D
data cartridge A term used to distinguish a
cartridge onto which a tape drive may write
data from a cartridge used for cleaning or
diagnostic purposes.
diagnostic cartridge A data cartridge with
a “DG” label that is used for diagnostic
routines.
drive and electronics module The module
in an Product Name library that contains the
electronics control module, power
distribution units (PDUs), power supplies,
accessory racks and equipment, and tape
drives for the library.
drive bay A partitioned section of the tape
drive array assembly that holds one tape
drive tray assembly.
drop-off slots Slots used to hold a
cartridge in the event of a robot failure that
occurs while a cartridge is in the robot hand.
dWWN See dynamic World Wide Name.
dynamic World Wide Name A feature that
applies dynamic names to network devices
rather than fixed names. When a dWWN-
named device is replaced, it is assigned the
same WWN as the one replaced, preventing
reconfiguration of the network.
E
ECM See electronics control module.
electronics control module (ECM) The
assembly that:
• Processes commands from a host
system
• Coordinates the activities of robots,
elevators, pass-thru ports, and tape
drives
• Monitors status inputs from sensors
and switches
elevator The device that transports
cartridges vertically, across rail boundaries.
emergency power-off (EPO) (1) A safety
scheme that allows a “power down” of a
subsystem or a system as a whole instead
of powering it down component-by-
component.
(2) A safety switch on a machine or in a data
center that allows a user to immediately
power down a machine or a data center
power supply by cutting off the external
source power.
Emergency Robotics Stop A button on
the Customer Interface Module keypad that
removes power to the robotics power grid,
leaving the remaining library power on.
Enterprise Systems Connection
(ESCON)
A set of fiber-optic based
products and services developed by IBM
that allows devices within a storage
environment to be dynamically configured. A
channel-to-control unit I/O interface that
uses optical cables as a transmission
medium.
