gripper
expanded mailsot
An optional library configuration to increase the capacity of the Mailslot from four to
19 cartridges. A logical entity containing four slots in the Standard Mailslot plus 15
slots in the Base Module right magazine (the Mailslot Expansion).
expansion cable
A cable used to connect expansion modules to Module 1. Each end of the cable has a
USB A style connector.
expansion chassis
The sheet metal and plastic chassis that makes up the framework for Module 2–15.
expansion module
A module that can be added to the bottom of an existing library to increase its capacity
for drives and tape cartridges (tapes). The module consists of the expansion chassis, a

can remove the cartridge. Also called eject.
FC
See Fibre Channel.
fiber optics
The branch of optical technology concerned with the transmission of radiant power
through fibers made of transparent materials such as glass, fused silica, and plastic. (E)
fiber-optic cable
A cable made of ultra-thin glass or silica fibers which can transmit data using pulses of
laser light. Fiber-optic cables have several advantages over copper cables: they have
much less signal loss; they allow information to be transmitted at higher speeds and
over longer distances; they are not affected by external electrical noise; and they are
better for transmissions which require security.
Fibre Channel
The National Committee for Information Technology Standards standard that defines
an ultrahigh-speed, content-independent, multilevel data transmission interface that
supports multiple protocols simultaneously. Fibre Channel supports connectivity to
millions of devices over copper or fiber-optic physical media and provides the best
characteristics of both networks and channels over diverse topologies.
front control panel
An assembly mounted on the front of the base chassis. It includes the touch screen
operator panel, various LEDs and switches, and associated electronics.
get
An activity in which a robot obtains a cartridge from a slot or drive.
gripper
The portion of the hand assembly that grasps and holds a cartridge.
