short-wave cable
In Fibre Channel technology, a laser cable
that uses a wavelength of 780 nanometers
and is only compatible with multi-mode
fiber.
shuffle
In HD frames, the process of moving
cartridges in lower tiers into the gripper
or other available slots to access
cartridges in higher tiers.
shuttle car
The mechanism that carries one tape
cartridge through the shuttle connection
to another library string. Each shuttle car
carries one tape cartridge at a time.
shuttle complex
Two or more parallel high density (HD)
library strings that are interconnected by
one or more shuttle connections.
shuttle connection
Also referred to as Model SC1, the shuttle
connection is comprised of one shuttle
car, two or more shuttle stations, and one
or more spans between these shuttle
stations. Each shuttle connection supports
one shuttle car.
shuttle span
One or more shuttle spans are linked
together to form a shuttle connection
between HD frames in parallel library
strings. Shorter shuttle spans support
distances between library strings ranging
from 762 mm (30 in) to 1 524 mm (60 in).
Longer shuttle spans support distances
between library strings that range from 1
524 mm (60 in) to 2 743.2 mm (108 in).
shuttle station
The shuttle station mounts on top of an
HD frame. It consists of a base pad and a
shuttle slot. The shuttle slot docks into the
base pad. When the shuttle slot is all the
way down into the frame station, it can
accept or deliver a cartridge. Each shuttle
station has its own import/export element
(IEE) address.
Simple Network Management Protocol (SNMP)
In the Internet suite of protocols, a
network management protocol that is
used to monitor routers and attached
networks. SNMP is an application layer
protocol. Information on devices that are
managed is defined and stored in the
application's Management Information
Base (MIB).
single-phase power
Pertaining to the TS4500 tape library,
electricity that is transmitted via three
wires (line, neutral, and ground), with a
line-to-neutral voltage of 200-240 V ac.
SLP See Service Location Protocol.
Small Computer Systems Interface (SCSI)
A standard that is 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 160 megabytes per second). The
variations include:
v Fast/Wide SCSI: Uses a 16-bit bus, and
supports data rates of up to 20 MBps.
v SCSI-1: Uses an 8-bit bus, and supports
data rates of 4 MBps.
v SCSI-2: Same as SCSI-1, but uses a
50-pin connector instead of a 25-pin
connector, and supports multiple
devices.
v Ultra SCSI: Uses an 8- or 16-bit bus,
and supports data rates of 20 or 40
MBps.
v Ultra2 SCSI: Uses an 8- or 16-bit bus
and supports data rates of 40 or 80
MBps.
v Ultra3 SCSI: Uses a 16-bit bus and
supports data rates of 80 or 160 MBps.
v Ultra160 SCSI: Uses a 16-bit bus and
supports data rates of 80 or 160 MBps.

Specialist web interface
A platform-independent, web-based
interface that allows a user to configure
and monitor the TS3500 tape library from
a remote location.
