A local area networking technology. Ethernet can transport any of several
upper layer protocols, the most popular of which is TCP/IP.
A change of condition to a library component or a change of state that can
be recorded in the event log. When an event occurs, an e-mail or pager alert
can be sent to specified users.
One of the columns of cartridge slots in a Media Expansion Module
(MEM).The carousel in a MEM contains 18 facets, with 60 slots (rows) per
facet.
One of the communication protocols supported by the library. Fibre
Channel is a set of standards for a serial I/O bus.
Any the cartridge slots that can be installed on the inside of the library's
front panel instead of an I/O port.
The library assembly that includes the picker mechanism and the barcode
reader. The handler moves side to side on the X-axis, up and down on the
Y-axis, and in and out on the Z-axis. It rotates on the Theta-axis. The
handler is referred to as a medium transport element in the SCSI
standard.
Host bus adapter card.
A circuit board installed in one of the system controller's four expansion
slots that allows the library to attach to and communicate with a SCSI bus
or Fibre Channel network. The HBAs supported by the library have two
ports, which means you can connect two networks or SCSI buses to each
card.
A library component, such as tape drive assemblies, fans, and power
supplies, that can be replaced without removing system power.
An opening on the front of the library through which cartridges can be
inserted or removed without exposing internal library components.
The pairs of LED emitters and detectors in the front of the library that
detect whether a cartridge is protruding from a slot or whether someone
has reached into the library. Also referred to as the light curtain.
Light emitting diode. The library contains five LEDs on its front panel to
indicate its operating status. Additional LEDs are used on each power
supply and tape drive assembly.
A robotic media handler that is capable of storing multiple pieces of
removable media and loading and unloading them from one or more tape
drives in arbitrary order.
