Installation Overview  
Installation of the drive can be divided into distinct  
phases. Some of these may not be applicable to all  
system installation requirements. Refer to the indi-  
vidualdriveinstallationsectionsforspecificinformation  
on your drive model.  
Drive configuration: Select those drive features  
that are appropriate to install the drive in the system.  
In"W/WD"modelsthisisdonebyinstallingorremov-  
ing user configuration jumpers found on the drive  
PCB. For "WC/DC" models, some of the configura-  
tion parameters can be set over the 80 pin interface.  
Mechanical installation: After setting up the drive  
configuration the drive must be mechanically in-  
stalled into the host system and the power and I/O  
cables attached. Previously mentioned precautions  
should be observed.  
• CMOS configuration: SCSI drives should not be  
definedintheCMOS.TheSCSIhostadapterusesits  
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.

Low-Level formatting: All Hawk 2LP wide family  
drive models are low-level formatted at the factory  
and do not require this step during installation. If an  
installeddriveislow-levelformatted,alluserdatawill  
be lost.  
Note: SeagateTechnologyassumesnoliabilityforlost  
user data.  
Partitioningandhighlevelformatting:A drivecan  
be subdivided into "partitions" which behave as indi-  
vidual drives within the system. Consult the system  
documentation for instructions on partitioning and  
high level formatting. Information is also available in  
bookstores and libraries.

Product repair information  
Service requirements  
The special facilities required for the manufacture of  
these drives generally prohibit repair in the field. If  
problemsoccurduringinstallation,pleasecontactyour  
supplier for assistance. Do not attempt to disassemble  
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-  
icing items in the sealed HDA (heads, media, actua-  
tor, etc.) require special facilities. The drive contains  
no user purchasable parts or PCBs.  
• Opening the sealed HDA voids the drive warranty.  
• Applying a soldering device to the components on  
the PCB voids the drive warranty.  
• Do not connect or disconnect cables without first  
removing power from the drive.

• 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.  
Shipping:  
When transporting or shipping a drive, a Seagate  
approved container must be used. Keep your original  
box. They are easily identified by the Seagate Ap-  
proved Package label. Shipping a drive in a non-  
approved container voids the drive warranty.

Hawk 2LP (Wide) Installation Guide, Rev. A  
Initial setup information  
For the initial setup connect the cables or plug into a  
mounted connector (if applicable), set the drive ID on  
the bus and enable or disable the I/O line terminator  
resistor packs (Hawk 2LP family "W" models only).  
These procedures are described in paragraphs follow-  
ing. Note whether drive model number ends in W, WD,  
WC or DC.  
SCSI interface cable connection  
The Hawk 2LP family wide drives are SCSI interface  
drives. System connection on "W" and "WD" models is  
via a 68 pin SCSI connector. System connection for  
"WC" and "DC" models is via an 80 pin SCSI and DC  
power connector. The "WC" and "DC" models plug  
directly into a PCB or bulkhead mounted mating 80 pin  
connector. "WC" and "DC" drives should not be con-  
nectedtothehostviaacable/connector. Pin1isnoted  
inFigure2.Somecableshaveacontrastingcolorstripe  
on one edge to indicate pin 1. On the Hawk 2LP wide  
drives 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 recommended at the cable in  
drives using cables. Do not block system cooling air  
flow in routing of cables.  
Hawk 2LP (Wide) Installation Guide, Rev. A  
17  
DC Power connection  
Hawk 2LP family "W/WD" model drives receive DC  
power through a 4 pin connector mounted on the PCB  
in line with the SCSI I/O connector. See figure below.

(See Figure 2b).

Hawk 2LP (Wide) Installation Guide, Rev. A  
SCSI address selection  
On "W" and "WD" model drives, make sure that the  
SCSI bus address jumper(s) are properly set for the  
bus address assigned to the drive. See Figures 3a and  
3b showing the bus address select header and the  
jumper configurations that select addresses 0 through  
15. ID7 has the highest priority during bus arbitration  
(on both 8 and 16 device systems). Bus arbitration  
prioritydecreasestoID0, thenID15downtoID8. ID8is  
the very lowest priority. Typically the primary boot  
deviceissettoID0, thehostisID7andthesubsequent  
SCSI drives are jumpered as appropriate for the par-  
ticular system involved.  
If the drive "Busy" LED shows no on/off activity when  
the host is trying to communicate with it, an incorrect  
bus address selection at the drive should be suspect-  
ed.  
On "WC" and "DC" model drives the SCSI ID can be  
and presumably will be, set over the 80 pin interface by  
the host computer. Unless directed to do so by the  
systemdocumentation, nojumpersshouldbeinstalled  
foraddressselection.On"WC"and"DC"modeldrives,  
the host system also has complete control over motor  
start functions, so no Motor Start or Delayed Motor  
Start Jumpers should be installed.  
Hawk 2LP (Wide) Installation Guide, Rev. A  
19  
Terminator resistor packs  
As a factory installed option, Hawk 2LP family model  
"W" drives can have terminator resistor packs that are  
permanently installed, but can be enabled or disabled  
by jumper plug. See jumper in Figure 3a. If you are  
installing a single drive, the terminator resistor packs  
mustremainenabled. Ifyouareinstallingmultiplehard  
disc drives, disable the termination resistor packs from  
all the drives but the one connected to the end of the  
SCSI I/O cable.  
Model numbers that end in "WD" and "DC" have  
differential I/O circuits. These drives and "WC" model  
drives have no provisions for terminators on the drive  
PCB. The system manufacturer must provide some  
external means of I/O line termination. The Hawk 2LP  
family "W/WD" model drives can provide power for  
external terminators if theTP jumper is installed on the  
last position on the right end of J2. See Figure 3a.  
Do not mix "W" and "WD" or "WC" and "DC" model  
drives on the same I/O bus.

Read/Write head auto-park  
Seagate disc drives described herein park the heads  
automatically at power off. This feature requires no  
operator intervention.  
Optional parity bit enable  
Some systems require parity bit checking. Consult the  
system documentation for the specific requirements.  
See Figure 3a for location of Parity Bit enable jumper.  
Jumper-installed enables parity reporting by the SCSI  
bus.

On Hawk 2LP family "W/WD" drives either J6 (on the  
front of the drive) or J1-auxiliary (at the rear, next to the  
DC Power connector) may be used to set the drive ID.  
To avoid possible incorrect ID setting, do not use both  
J1-auxiliary and J6 for ID selection. The following  
figures show where these headers are located on the  
different drives covered by this manual. See notes

Notes for Figure 3a, 3b and 3c:  
[1] Notes explaining the functions of the various jump-  
ers on jumper header connectors J2, J1-auxiliary  
andJ6aregivenbelowinlefttorightorderofjumper  
position. The term "default" means as standard  
OEM units are configured when shipped from fac-  
tory."Off"meansnojumperisinstalled;"On"means  
a jumper is installed. Off or Onunderlinedis factory  
default condition.  
[2] The PCB on "WC" and "DC" models does not have  
connector J1-auxiliary, but has a single 80 pin J1  
connectorhavingcombinedSCSII/OandDCpower  
connector instead of the 68 pin SCSI I/O, 12 pin  
auxiliary, and 4 pin DC power connectors that "W"  
and "WD" models have. Included among the 80 J1  
pins are the SCSI ID, Motor Start and Delayed  
Motor Start select functions, and the remote BUSY  
LED signal. Do not use J2 and J6 for these four  
functionsifthehostusestheonesincludedinthe80  
pin J1 connector.  
[3] Drive ID may be established by installing jumper  
plugsinoneofthepatternsshowninFigures3aand  
3borbypluggingontoJ6orJ1-auxiliaryacablethat  
leads to an external ID selection circuit. Jumper  
plugs on both J6 and J1 auxiliary, or J6 and an  
external ID selection source should not be used.  
See[4]forotherfunctionsofthesetwoheadersthat  
are time-shared with the drive ID function.

Hawk 2LP (Wide) Installation Guide, Rev. A  
[4] The drive time-shares the ID and BUSY LED func-  
tions of J6 and J1-auxiliary. That is, a cable may be  
attached to one of these headers to pick up the  
signal that lights the external BUSY LED indicator.  
If lines for external ID selection are not also in-  
cluded in the cable, jumper plugs must be used on  
theheadernothavingacableconnectedinorderto  
establish drive ID. The drive reads the ID from J6  
and J1-auxiliary for 250 ms after power-on or drive  
reset, and then uses these headers for the LED  
function the remainder of the time.  
[5] "W" models only.

Drive installation  
This section describes the physical mounting of the  
drive in the host cabinet and the logical installation as  
a system member, which is called drive setup.  
Disc drive mounting  
Do not touch the connector pins or any PCB compo-  
nents without observing static-discharge precautions.  
Always handle the drive by the frame only.  
The drive may be mounted in any orientation.  
• See notes in Figures 4 and 5 pertaining to proper  
drive installation.  
• Verify that all connections between the drive and the  
hostsystemarecorrectlyinstalled.Mostcableshave

Hawk 2LP (Wide) Installation Guide, Rev. A  
Do not power up the host system until the drive is  
mounted and the system cover is replaced.  
• Connect DC power connector to the drive ("W/WD"  
models only).  
• Replace the Host System cover.  
• Turn on DC power.  
• Boot the system from the floppy drive or from a  
previously installed hard-drive if there is one.  
• Proceed with drive setup of the new hard drive.  
Grounding  
Signal ground (PCB) and HDA ground are connected  
together in the Hawk 2LP wide drives and cannot be  
separated by the user. The equipment in which the  
drive is mounted is connected directly to the HDA and  
PCB with no electrically isolating shock mounts. If it is  
desired for the system chassis to not be connected to  
the HDA/PCB ground, the systems integrator or user  
must provide a nonconductive (electrically isolating)  
method of mounting the drive in the host equipment.  
Hawk 2LP (Wide) Installation Guide, Rev. A  
37  
SCSI interface drives  
The SCSI interface handles both drive geometry and  
defect management internally. The "no drive installed"  
option is selected for systems with SCSI drives.  
All SCSI interface drives are low-level formatted at the  
factory. You may wish to low-level format the drive to  
optimize its performance for your system. Consult the  
controller documentation for information on low-level  
formatting. Partitioning and high-level formatting can  
be done through DOS by way of the FDISK utility for  
partitioning, and FORMAT for high-level formatting.  
Consult your DOS manual for FORMAT and FDISK  
command options.
