3. Installing the internal autoloader
This chapter describes how to configure, mount, and attach
cables to the
internal
Scorpion 96 autoloader. For instructions
on installing an external autoloader, see Chapter 4, beginning
on page 16.
Configuring the internal autoloader
Before you install the internal version of the Scorpion 96 in
your computer, you may need to configure the drive to work
with your system.
Default settings
The default settings for the internal drive are listed below:
• SCSI termination is disabled.
• SCSI terminator power is disabled.
• The drive is set for SCSI ID 0.
• MRS checking is enabled
(the drive will not read non-MRS tapes).
• Parity checking is enabled.
• Data compression is enabled.
• Power-on self-test diagnostics are enabled.
If these default settings are appropriate for your computer
system, then continue to “Mounting the internal autoloader”
on page 14.

DAT Autoloader Installation Manual 7
Changing the default settings
To change one or more of the default settings (including SCSI ID
or SCSI termination), you will need to use one of the following:
External dip-switches located on a cutout on the top of
the drive:
• SCSI ID
• MRS checking
• Parity checking
• Data compression
• Power-on self-test enable
Jumpers on the back of the drive:
• SCSI termination
• Terminator power
• Remote SCSI address selection
Internal dip switches located on the autoloader drawer:
• Autoload first tape
• Display orientation
• Display language
• Display intensity
➤ Note. Whenever possible, power down the drive before
changing jumpers or dip switches. Your changes will take
effect when the drive is subsequently powered on.

SCSI ID: Switches 1, 2, and 3 (the SCSI-ID bit switches) are
used to select the SCSI ID used by the drive, as shown in
Figure 3. You must select a SCSI ID that is not used by any
other devices on the SCSI bus.
➤ Note. In some computers the SCSI ID 0 (the autoloader’s
default setting) may be used by the bootable hard drive.

DAT Autoloader Installation Manual 9
MRS Mode: If Switch 4 is OFF, the autoloader writes or
reads both MRS and non-MRS 4mm media. If Switch 4 is ON
(the default), the autoloader only writes to MRS media.
Data Compression: If Switch 6 is OFF (the default), DDS-
DC data compression is enabled during writing. If Switch 6 is
ON, DDS-DC data compression is DISABLED during writing.
During a read operation, compressed data is always
decompressed, regardless of the position of this dip switch.
Self-test: Switch 8 enables or disables execution of power-
on self-test (POST) diagnostics when the autoloader is first
powered on. If this switch is ON (the default), the autoloader
responds to SCSI commands only after successful
completion of the test (about 5 seconds).
Jumpers on back of drive
On the back of the Scorpion 96 are five pairs of jumper pins,
shown in Figure 4. The two pairs on the left are used to set
SCSI termination and termination power. The other three
pairs of jumper pins are used to set the SCSI ID of the drive
remotely (for example, if the drive is mounted in an external
housing).

SCSI termination: The drive is shipped with SCSI
termination disabled. This setting is appropriate if the drive is
attached in the middle of a SCSI chain with other SCSI
devices. If the autoloader is the only device or the last device
on a SCSI chain, you must install a jumper on these two pins.
Terminator power: The jumper pins closest to the power
connector are used to enable +5-volt terminator power if
needed for terminators or other SCSI devices. The factory
default setting (termination power disabled) is appropriate for
most systems. If you need to enable terminator power, place
a jumper firmly over both pins.
➤ Note. A terminator power fuse is located beside the
terminator power jumper. The terminator power fuse is
designed to prevent damage to Autoloader components
in case terminator power is shorted. For example, If
terminator power is enabled and the SCSI cable is
connected upside down, this fuse will blow to prevent
damage to the Autoloader itself. If this occurs, return the
Autoloader to an authorized repair facility.
Remote SCSI addressing: Six of the pins on the back of the
drive are used for remote SCSI address selection (for
example, if the autoloader is mounted in an external
housing). The table below indicates where jumpers should be
placed to configure the drive for different SCSI IDs.

➤ Note. If you use these jumpers for remote SCSI ID
selection, all three of the SCSI ID dip switches on the top
of the drive
must be set to OFF
.
