INSTALLATION
Water and Moisture –Do not use
power-line operated units near water -
for example, near a bathtub,
washbowl, kitchen sink, or laundry
tub, in a wet basement, or near a
swimming pool, etc.
Power-Cord Protection –Route the
power cord so that it is not likely to be
walked on or pinched by items placed
upon or against them, paying
particular attention to the plugs,
receptacles, and the point where the
cord exits from the appliance.
Accessories –Do not place the unit on
an unstable cart, stand, tripod, bracket,
or table. The unit may fall, causing
serious injury to a child or an adult,
and serious damage to the unit. Use
only a cart stand tripod, bracket, or
table recommended by the
manufacturer.
Ventilation –The slots and openings
in the cabinet are provided for
necessary ventilation. To ensure
reliable operation of the unit, and to
protect it from overheating, these slots
and openings must never be blocked or
covered.
•Never cover the slots and openings
with a cloth or other materials.
•Never block the slots and openings
by placing the unit on a bed, sofa,
rug or other similar surface.
•Never place the unit in a confined
space, such as a bookcase, or built-
in cabinet, unless proper ventilation
is provided.
SERVICE
Damage Requiring Service –Unplug
the unit from the wall outlet and refer
servicing to qualified service
personnel under the following
conditions:
•When the power cord or plug is
damaged or frayed.
•If liquid has been spilled or objects
have fallen into the unit.
•If the unit has been exposed to rain
or water.
• If the unit has been subject to
excessive shock by being dropped,
or the cabinet has been damaged.
•If the unit does not operate normally
when following the operating
instructions. Adjust only those
controls that are specified in the
operating instructions. Improper
adjustment of other controls may
result in damage and will often
require extensive work by a
qualified technician to restore the
unit to normal operation.
•When the unit exhibits a distinct
change in performance - this
indicates a need for service.
Servicing –Do not attempt to service
the unit yourself as opening or
removing covers may expose you to
dangerous voltage or other hazards.
Refer to all servicing to qualified
service personnel.

Overview
The SDX-400V drive is a high-capacity data storage device using the
Advanced Intelligent Tape (AIT) technology. The SDX-400V drive
achieves high data reliability through Read-After-Write, an additional level
of error correction code, and other features.
The SDX-400V drive stores data on tape using standard formats called AIT
(Advanced Intelligent Tape) and ALDC.

Introduction
About the AIT Drive
The SDX-400V is an internal AIT drive unit that uses data cartridges
conforming to the AIT-1 format.
Features
The AIT drive unit SDX-400V has the following features:
•Supports reading and writing to data cartridges conforming to the AIT-1
format.
•Read-After-Write function and third-level error correction code
guarantee high data reliability.
•Data compression provides 91 gigabytes of storage on 230 m tape-length
cartridge.*1
The native capacity is 35 gigabytes of storage on 230 m tape-length
cartridge.
•Stored data is automatically checked for compression.
•Wide Ultra SCSI LVD/SE interface is fully supported for host computer
access.
*1 This is assuming 2.6 : 1 compression ratio.
The degree of data compression attained while recording data varies according to
system environment and data type.

Precautions
Installation
Avoid placing the drive in a location subject to:
–high humidity
–high temperature
– mechanical shock and vibration
–direct sunlight
*For details, see “Specifications” on page 25.
Operation
•Do not move the drive while it is operating. It may cause malfunction.
• Avoid exposing the drive to sudden changes from a low to high
temperatures. This may cause water condensation to collect inside the
drive. If the ambient temperature should suddenly rise while the drive is
turned on, wait at least one hour before turning on the drive. If you
attempt to operate the drive immediately after a sudden increase in
temperature, a malfunction may occur.
• Turning off the power to the drive while it is writing to tape may cause
the tape to become unreadable. All previously negotiated parameters will
be lost, whenever power to the drive is cycled.
Transportation
•Keep the original packing materials to facilitate safe transportation of the
drive.
•Always remove the tape/media cartridge before moving the drive. After
removing the drive from the computer, repack the drive into its original
packing.

SCSI Termination
The SDX-400V conforms to the Microsoft PC97 standard which requires
the internal (naked) drive to be terminated with an external terminator.
Microsoft PC97 SCSI requirements
SCSI peripherals must not terminate the bus. Both internal and external cable ends are
instead terminated by plug-in connectors.
