power cord plug. On a power cord, the male fitting
for making an electrical connection to a circuit by
insertion into a receptacle.
power receptacle. The mounted female electrical
fitting that contains the live parts of the circuit.
power switch. Located at the rear of the 3580 Ultrium
2 Tape Drive, a toggle switch that lets you turn the
power to the tape drive on or off. To power the tape
drive on, push the switch to | ; to power it off, push
the switch to 0.
R
read. To acquire or interpret data from a storage
device, from a data medium, or from another source.
relative humidity. The ratio of the amount of water
vapor actually present in the air to the greatest amount
possible at the same temperature.
remove. Pertaining to the 3580 Ultrium 2 Tape Drive,
to take an ejected tape cartridge from the tape drive.
reset.
To restore to the original state of operation.
retention screws.
Pertaining to the connector on a
cable, two screws on either side of the connector that
secure it to its mating connector.
RS-422 interface. Between the 3580 Ultrium 2 Tape
Drive and the message display processor, the standard
interface approved by the Electronic Industries
Association (EIA) for connecting serial devices. The
interface includes the cable, connectors, and firmware
for the drive. The RS-422 interface supports multipoint
connections.
S
scratch cartridge. A data cartridge that contains no
useful data, but can be written to with new data.
Synonymous with blank cartridge.
SCSI. Small computer systems interface.
SCSI-2. Small computer systems interface-2.
SCSI address switch. Located at the rear of the 3580
Ultrium 2 Tape Drive, a switch that, when pressed,
increments or decrements to a unique numeric ID
(address) that identifies the tape drive to the server.
SCSI bus. (1) A collection of wires through which
data is transmitted from one part of a computer to
another. (2) In networking, a central cable that connects
all devices on a local-area network (LAN). (3) A generic
term that refers to the complete set of signals that
define the activity of the Small Computer Systems
Interface (SCSI). Synonymous with SCSI bus cable and
SCSI cable.
SCSI bus cable. See SCSI bus.
SCSI cable. See SCSI bus.
SCSI command. An operation performed by a target
(tape drive) for an initiator (server). The command is
initiated by the operator from the host console.
SCSI connector. One of the set of all female and male
connectors on the SCSI bus.
SCSI device. Anything that can connect into the SCSI
bus and actively participate in bus activity.
SCSI host adapter card. The logic card that connects a
server to the SCSI bus cable. Synonymous with SCSI
controller.
SCSI ID. The hexadecimal representation of the
unique address (0-F) which a user assigns to the 3580
Ultrium 2 Tape Drive and which is used in SCSI
protocols to identify or select the drive. The user
normally assigns and sets the SCSI ID when installing
the drive.
SCSI wrap tool. A device that attaches to the SCSI
connector on the 3580 Ultrium 2 Tape Drive and
enables internal tests on the SCSI interface.
seat, seated. (1) To fit to. (2) To ensure that one object
is fitted to another object.
server. A functional unit that provides services to one
or more clients over a network. Examples include a file
server, a print server, and a mail server. The RS/6000
®
,
AS/400, HP, and Sun are servers. Synonymous with
host.
ship group. The group of supplies, cords, or
documentation that is shipped with the 3580 Ultrium 2
Tape Drive.
shipping environment.
The temperature, relative
humidity rate, and wet bulb temperature of the
environment to which the 3580 Ultrium 2 Tape Drive is
exposed when being transferred from one location to
another.
single-character display. Located on the front of the
3580 Ultrium 2 Tape Drive, an LED that presents a
single-character code which represents error conditions,
informational messages, diagnostic functions, or
maintenance functions. The single-character display is
blank during normal operation of the tape drive.
Small Computer Systems Interface (SCSI).
A
standard used by computer manufacturers for attaching
peripheral devices (such as tape drives, hard disks,
CD-ROM players, printers, and scanners) to computers
(servers). Pronounced “scuzzy.” Variations of the SCSI
interface provide for faster data transmission rates than
standard serial and parallel ports (up to 80 megabytes
per second). The variations include:
