SDX-400C Tape Drive

The SDX-400C drive is a high capacity data storage device using
Advanced Intelligent tape AIT (Advanced Intelligent Tape) technology.
The SDX-400C drive achieves high data reliability through Read-After­Write, an additional level of Error Correction Code, and other features.

The SDX-400C drive stores data on tape using a standard format called
AIT and ALDC formats.

Precautions

Installation

Avoid placing the drive in a location subject to:

– high humidity
– high temperature
– mechanical shock and vibration
– direct sunlight

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 in

temperature. 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 transportation of the
drive.

• Always remove the tape before moving the drive. After removing the
drive from the computer, repack the drive into its original packing.

Notice of SCSI Termination

r

The SDX-400C 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.
