encryption
The process of changing data into a form that cannot be read until it is deciphered,
protecting the data from unauthorized access and use.
Ethernet
A local-area, packet-switched network technology. Originally designed for coaxial
cable, it now also runs over shielded, twisted-pair cable. Ethernet is a 10 or 100
Megabytes-per-second LAN.
expansion cable
A cable used to connect modules 2–10 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 2–10.
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 module controller, up to two power supplies, up to two half-height LTO
Ultrium tape drives, a left magazine, and a right magazine. The expansion module
connects to the base module by an expansion cable.
export
The action in which the device places a cartridge into the mailslot so that the operator
can remove the cartridge. Also called eject.

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 and/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.
