Static electrical charges can accumulate quickly
onpersonnel,clothingandsyntheticmaterials.The
electrostatic fields due to these charges when
brought in close proximity to susceptible circuit
assemblies and components, can result in de-
graded reliability or immediate failure of the affect-
ed component or assembly.
To insure optimum reliable equipment operation, it
is required that technical support personnel dis-
charge themselves by wearing a grounding strap
around the wrist and be connected to a grounding
terminal while working in the vicinity of, and while
handling EOS/ESD susceptible assemblies/parts.
Ifunavailable,ground yourself frequentlyby touch-
ingthemetalchassisofthesystembeforehandling
any components (this helps only if the system is
connected to a ground). Avoid static-inducing car-
peted areas. This procedure is especially impor-
tant when handling printed circuit boards (PCB's).

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 theindividual driveinstallationsections
for specific information on your drive model.
•Drive configuration: Select those drive features that are
appropriate to install the drive in the system. This is done by
installing or removing user configuration jumpers found on
the drive PCB.
•Mechanical installation: After setting up the drive configu-
ration the drive must be mechanically installed into the host
system and the power and I/O cables attached. Previously
mentioned precautions should be observed.
• CMOS configuration: SCSIdrivesshould not bedefinedin
the CMOS. The SCSI host adapter uses 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 2LP Family Installation Guide, Rev. A 9
_____________________________________________________________________________________________________________
•Low-Level formatting: All Hawk 2LP family drive models
are low-level formatted at the factory and do not require this
step during installation. If an installed drive is low-level
formatted, all user data will be lost.
Note: Seagate Technology assumes no liability for lost user
data.
•Partitioning and high level formatting: A drive can be
sub-divided into "partitions" which behave as individual
driveswithinthesystem.Consultthe system documentation
for instructions on partitioning and high level formatting.
Information is also available in bookstores and libraries.

DC Power connection
The drives receive DC power through a 4 pin connector
mountedonthePCBnexttotheSCSII/Oconnector.Seefigure
below.
Figure 1. DC power connection, 50 pin SCSI I/O
connector
SCSI address selection
Make sure that the SCSI bus address jumper(s) are properly
set for the bus address assigned to the drive. See figures 3a
and3b showingthebus addressselectheader andthejumper
configurations that select addresses 0 through 7. Typically
theprimarybootdeviceissettoID0,and thesubsequentSCSI
drives are jumpered in ascending order. Bus addresses 0
through 6 should be used (the host adapter usually uses
address 7). If the drive 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 suspected.
