when installed in an enclosure that provides reason-
able shielding. As such, the drive(s) are capable of
meeting the Class B limits of the FCC Rules and the
RegulationsoftheCanadianDepartmentofCommuni-
cations.

Before you begin
Verify that the system is switched off and discon-
nected from main power before any installation is
attempted.
Protect yourself, the drive, and your valuable pro-
grams and data by reading the following cautions
and warnings.
•Donot unpackdrivefrom its staticshielded bag until
you are ready to install it in the system.
•Always handle the drive by the frame or casting.
•Do not touch printed circuit board (PCB) or the I/O
connector pins.
•Never apply pressure to the PCB or to the drive top
cover.
•Donot tamperwithsealed top cover.Doing so voids
your warranty. The drive contains no user service-
able components. See Product Repair section for
moreinformation.
•Visually inspect the shipping container for any obvi-
ous damage.

Installation Overview
Installation of the drive can be divided into distinct
phases as outlined below. Some of these may not be
applicable to your particular installation requirements.
Refer to the individual drive installation sections for
specific information on your drive model.
•Driveconfiguration:Theusermustselectwhichof
thedrivefeaturesareappropriatetoenableforinstal-
lationintheirsystem.Thisisdonebywayoftheuser
configuration jumpers found on the drive PCB.
•Mechanical installation: After setting up the drive
configuration the drive must be mechanically in-
stalledinto the host system and the power and I/O
cables attached. Previously mentioned precautions
should be observed
•SCSI drives should not be defined in the CMOS:
The SCSI Host adapter has its own BIOS to handle
the Input/output procedures. The CMOS setting for
SCSI drive is either drive type zero, or the "no drive
installed"option.

Hawk 4 (Wide) Family Install Guide, Rev. A 9
___________________________________________
•Low-level formatting: After the drive has been
properly configured for the system, it does not need
to be low-level formatted, as this has been done by
the factory and does not require this step during
installation. (The low-level format writes the sector
boundariesandtrackinformationtothedrive).Defect
managementinformationisreadfromthedrivebythe
host system when required in the installation proce-
dure. If an installed drive is low-level formatted, all
user data stored on the drive will be lost.
Note. SeagateTechnologyassumes noliability for
lost user data.
•Partitioningandhighlevelformatting:A drivecan
be sub-divided into "partitions" which behave as
individualdriveswithinthesystem.Seeyoursystem
documentation. Present day drive installation pro-
grams have menus that lead you through these
installationprocedures.

Product repair information
Service requirements
The special facilities required for the manufacture of
these drives generally prohibit repair in the field. If
problemsoccurduringinstallation,pleasecontactyour
supplierforassistance.Donotattempttodisassemble
or repair. Drives should be sent to the repair depot
through the purchase source, if possible. Please ob-
serve the following cautions.
Caution.
•Handle drive with care. Do not drop or bump hard.
•Never remove the cover of these disc drives. Serv-
icingitems in the sealed HDA (heads,media,actua-
tor,etc.)require specialfacilities. Thedrivecontains
no user purchasable parts or PCBs.
•Opening the sealed HDA voids the drive warranty.
•Applyingasolderingdevicetothecomponentsonthe
PCB voids the drive warranty.
•Place drive on a flat, static dissipative surface and
handle with extreme care. Always follow all EOS/
ESD precautions to avoid damage to the electrical
assemblies.

Initial setup information
For the initial setup connect the cables, set the SCSI
bus address and enable or disable (as required by
system configuration), the SCSI I/O line terminator
resistors (model "W" drives only). Note whether the
drivemodelnumberendsinW,WC,DCorWD.These
procedures are described in paragraphs following.
SCSI interface cable connection
Thedrives covered by this manual are SCSI interface
drives.For"W"and"WD""models, systemconnection
is via a 68 pin, SCSI connector. For "WC and DC"
models system connection is via an 80 pin SCSI
connector.Normally"WCandDC"modelsplugdirectly
intoaPCBorbulkheadmountedmating80pinconnec-
tor. Interfacing "WC and DC" models via a cable is not
recommended. Pin 1 is noted in Figures 1a and 1b.
Some cables have a contrasting color stripe on one
edge to indicate pin 1. The I/O connector is keyed by
virtue of its shape. There is only one way it can mate
with the mating input connector. Strain relief is recom-
mended at the cable for drives using cables. Do not
block system cooling air flow in routing of cables.

ST15230WC and ST15230DC model drives receive
power from the host computer through the 80 pin
combined SCSI I/O and power connector (not shown,
since a separate DC power cable not required). No

SCSI address selection

has the highest priority during bus arbitration on (both
8 and 16 device systems). Bus arbitration priority
decreases to ID 0, then ID 15 down to ID 8. ID 8 is the
verylowestpriority.Typicallytheprimarybootdeviceis
set to ID 0 the host is ID 7, and the subsequent SCSI
drives are jumpered as appropriate for the particular
system involved.
