Precautions
Caution. Observe the following precautions to avoid
electrostatic damage to the internal autoloader.
•Do not remove the drive from the antistatic bag until you
are ready to install it.
•Before you remove the drive from the antistatic bag, touch
a grounded metal surface to discharge any static
electricity buildup from your body.
•Hold the drive only by its edges and avoid direct contact
with any electronic components.
•If you need to put down the drive, lay it on top of the
antistatic bag or place it inside the bag.
Unpacking and inspection
Although Seagate autoloaders are inspected and carefully
packaged at the factory, damage may occur during shipping.
Follow these steps for unpacking the autoloader.
1. Inspect the shipping container. Notify your shipper
immediately if you find any damage.
2. Place the shipping container on a flat, clean, stable
surface. Then carefully remove the contents and verify
the packing list. If parts are missing or the equipment is
damaged notify your Seagate representative.
3. Save the drive container and packing materials in case
you ever need to ship the drive.

A-10 Scorpion 240 Autoloader Installation Manual
Installing the internal autoloader
This chapter describes how to configure, mount, and attach
cables to the
internal Scorpion 240 autoloader.
Configuring the internal autoloader
Before you install the internal version of the Scorpion 240 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:
•The drive is set for SCSI ID 6.
•Parity checking is enabled.
•SCSI terminator power is disabled.
•Data compression is enabled.
•Power-on self-test diagnostics are enabled.
•MRS checking is enabled
(the drive will not write to non-MRS tapes).
If these default settings are appropriate for your computer
system, then continue to “Mounting the internal autoloader” on
page A-15.
Changing jumper settings
To change the SCSI ID, parity checking, or termination power,
use the jumpers on the back of the drive, as shown in Figure
1 on the following page.
Note. Power down the drive before changing jumpers or dip
switches. Changes take effect when the drive restarts.

A-12 Scorpion 240 Autoloader Installation Manual
SCSI Address Selection (pins 1 through 8)
Each SCSI device on a SCSI bus must have a unique SCSI
ID. The SCSI controller or host adapter generally uses ID 7.
In some systems, the boot drive uses ID 0 or ID 1.
You can select an appropriate SCSI address used by the
drive by placing the appropriate jumpers on pins pairs 1-2
through 7-8, as shown in Figure 1.
Note: SCSI ID numbers 8 through 15 will only be recognized
if dip switch 9 is “ON.” See page A-14 for details.
Parity checking (pins 9 and 10)
If a jumper is installed on pins 9 and 10, parity checking is
enabled. If no jumper is installed, parity checking is disabled,
but parity is still generated by the drive.
Terminator power (pins 11 and 12)
If a jumper is installed on pins 11 and 12, terminator power is
enabled.
Note: The internal Scorpion 240 does
not provide SCSI
termination, and therefore should not be installed as
the last device in a SCSI chain. See “SCSI termination”
on page A-16 for more information.
If the terminator power jumper is installed, be careful not to
short the TERMPWR signal to ground. In the event of a short,
terminator power to the bus will be interrupted. After the short
is removed, a fuse in the drive will automatically reset,
restoring terminator power.
Changing dip-switch settings
To change data compression, MRS checking, power-on self-
test diagnostics, operating system settings, Wide/Narrow
SCSI selection, or the drive’s inquiry string, you must use the
dip switches on the underside of the internal drive.

Scorpion 240 Autoloader Installation Manual A-13
Figure 2 shows the location of dip switches on the underside
of the internal Scorpion 240. Each of these switches is
described in detail on subsequent pages.
Note. Power down the drive before changing jumpers or dip
switches. Changes take effect when the drive restarts.

Data compression (switches 1 and 2)
If switch 1 is ON (the default setting), hardware data
compression is enabled when the drive is powered on. If
switch 1 is OFF, hardware data compression is disabled at
power-on.
If dip switch 2 is ON (the default setting) then SCSI commands
can be used to enable or disable hardware data compression. To
prevent hardware data compression from being enabled or
disabled by SCSI commands, set dip switch 2 to OFF.
Media-recognition system (switch 3)
The media-recognition system allows the drive to determine
whether a given tape cartridge conforms to the DDS tape
standard. Use of non-DDS media may appear to give

A-14 Scorpion 240 Autoloader Installation Manual
satisfactory results, but the inferior specifications of such
media can cause data-integrity problems.
Switch 3 enables or disables the media-recognition system
(MRS). If switch 3 is ON (the default setting), the drive reads
and writes to MRS media and reads from but does not write to
non-MRS media. If switch 3 is OFF, the drive reads or writes
both MRS and non-MRS media.
Power-on self-test enable/disable (switch 4)
Switch 4 enables or disables execution of power-on self-test
diagnostics when the drive is powered on. If switch 4 is ON
(the default setting), the drive performs a power-on self test. If
switch 4 is OFF, the drive does not perform a power-on self
test.
Operating System configuration (switches 5 through 8)
Switches 5 through 8 are used to configure the drive for use
with UNIX, Novell, and Windows NT operating systems.
These procedures are described starting on page A-40. The
default setting for all four of these switches is ON.
SCSI Wide/Narrow (switch 9)
Switch 9 enables or disables SCSI Wide operation on the
SCSI bus. When switch 9 is ON (the default setting), the drive
is capable of operating in Wide (16-bit) SCSI mode. When
switch 9 is OFF, the drive will only operate as a Narrow (8-bit)
SCSI device.
Note: If switch 9 if set to OFF, the drive can only use SCSI ID
values 0 through 7.
Inquiry String (switch 10)
Switch 10 is used to select the Vendor ID that the drive
returns when queried with a SCSI Inquiry command. When
switch 10 is ON (the default setting), the Vendor ID will be
“SEAGATE DAT.” When switch 10 is OFF the Vendor ID will
be “ARCHIVE Python.” The “ARCHIVE Python” Vendor ID
may be used by independent software vendors to provide
software compatibility with previous Seagate DDS tape drives.

Mounting the internal autoloader
The Scorpion 240 must be mounted horizontally in a 5.25-
inch, full-height drive bay. Mount the drive using four M3.0
metric screws on the sides or bottom of the drive, as shown in
Figure 3. Do not use screws longer than 4 mm or you may
damage the drive.
Note. When mounting the drive, make sure that nothing
blocks the exhaust fan or the ventilation slots on the
bottom and rear of the autoloader.

Connecting the SCSI interface cable
Turn off all power to your computer and drive. Then connect a
68-pin wide internal SCSI cable from your SCSI controller to
the SCSI connector on the back of the autoloader. Make sure
that pin 1 on the SCSI controller and cable is connected to pin
1 on the drive. Figure 4 shows the location of SCSI pin 1 on
the drive’s SCSI connector. Pin 1 on the SCSI cable should
be indicated by a colored stripe.
Scorpion 240 drives can be used with two different types of
SCSI interfaces: Ultra2 SCSI (LVD) or “Wide” (16-bit) single-
ended SCSI. The drive can automatically detect whether it is
connected to an LVD or single-ended wide SCSI bus.
Note: The Scorpion 240 will not operate properly in a SCSI-1
environment.

SCSI Termination
The internal Scorpion 240 does
not provide SCSI termination.
For this reason, it should not be the last device on a SCSI
chain. Two termination examples are shown in Figure 5 on
the following page. If the drive is the only SCSI device, attach
the drive to the connector which is next to last on the SCSI

Scorpion 240 Autoloader Installation Manual A-17
chain and attach an LVD/single-ended multi-mode terminator
to the last connector in the chain.
