The physical design characteristics of the drive(s)
described herein, serve to minimize EMI radiation
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.
Note. It is the end users' responsibility to assure that
the drive(s) described herein meet the appro-
priateEMIrequirementsoftheirsystem.Shielded

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.
