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 29.
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 they are 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.
9
Useable Cartridges
The SDX-450V can be used with data cartridges marked with the AIT-E
Turbo, AIT-1 Turbo or AIT-1 logo.
The SDX-250V can be used with data cartridges marked with the AIT-E
Turbo logo.
Note
• Be sure to use only the cartridges designed specifically for AIT.
• Do not use anything but AIT cartridges with this system, as doing so can
damage the AIT drive. Although commercially available 8mm videotapes
resemble AIT cartridges in appearance, they have entirely different
specifications and cannot be used.
SCSI Termination
The SDX-450V and SDX-250V conform 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.
