Jumper setting
==============
Each disk drive has one or more option select header connectors on
the back, side or front where jumper plugs are installed to select
the way that the drive is to be configured or to select its ID on the
I/O bus. Headers used are the standard .100" center type.

The drive may be mounted in any orientation.
Mount to host system chassis using four 6-32 UNC screws. Three
mounting holes are in each side and four in the bottom of the drive.
The maximum length that the screws should extend into the side
chassis mounting holes is 0.15 inch (3.81 mm), and 0.20 inch (5.1 mm)
into bottom holes, measured from the outer surfce of the chassis.
Tighten the screws down evenly to approximately 8 inch-Ibl. Do not
over tigthen or force when screw does not seem to screw in easily
(threads not correctly engaged).
Verify that all connections between the drive and the host system are
correctly installed. Most cables have a contrasting color stripe
indicating pin 1.
The disc drive(s) are to be installed in a customer supplied
enclosure where the surrounding air does not exceed 50* C.
Grounding
---------
Signal ground (PCB) and HDA ground are connected together in the
ST3600 drive 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.
SCSI interface cable connection
-------------------------------
Models ST3600N/ND are SCSI interface drives. System connection is
via a 50-pin SCSI connector. Some cables have a contrasting color
stripe on one edge to indicate pin 1. Strain relief is recommended
at the cable. Do not block system cooling air flow in routing of
cables.
AT (IDE) interface cable connection
-----------------------------------
Model ST3600A Family drives AT (IDE) interface drive. System
connection is via a 40 pin AT (IDE) connector. Some cables have a
contrasting color strip on one edge to indicate pin 1. Use a strain
relief device at the cable. Do not block system cooling air with the
routing of cables.
Connect the AT (IDE) I/O connector cable end to drive 0 (master) and
if there is a drive 1 (slave) connect it to the connector in the
middle of the cable.
Order of locating the drives in the daisychain is not as important as
getting proper drive ID set up for the drives intended for drive 0
and drive 1.
DC Power connection
-------------------
The drive receives DC power through a 4 pin connector mounted on the
PCB next to the SCSI or AT (IDE) I/O connector.
Pin 1 +12 V
2 +12 V Return
3 + 5 V Return
4 + 5 V
SCSI Resistor terminator packs
------------------------------
If you are installing a single drive, the resistor terminator packs
must remain installed. If you are installing multiple hard disc
drives, remove the resistor termination packs from all the drives but
the one connected to the end of the SCSI I/O cable.
When reinstalling a resisor pack, note that pin 1 end on the pack is
denoted by a dot, a number one or a notch. Usually, a square pad on
the disc drive printed wiring assembly indicates pin 1 at the socket.
Model numbers that end in "ND" have differential I/O circuits and
these drives have no provisions for terminators that plug into the
drive PCB. The system manufacturer must provide some external means
of I/O line termination.
The AT (IDE) interface drives have permanent internal I/O line
termination and do not have removable terminators.
Features
SEAGATE ST3600 FAMILY INSTALLATION GUIDE 77738481, REV. A
Electromagnetic interference (EMI) considerations
-------------------------------------------------
The drive(s) described herein, as delivered, are designed for system
integration and installing into a suitable enclosure prior to use.
As such, the drive(s) described herein are supplied as a sub-assembly
and are not subject to Subpart J of Part 15 of the FCC Rules and
Regulations nor the radio Interference Regulations of the Canadian
Department of Communications.
However, the unit has been tested using proper shielding and ground-
ing and found to be compliant with the Class A limits of the FCC
Rules and the Regulations of the Canadian Department of
Communications.
Safety instructions
-------------------
The power supply must satisfy the safety requirements for SELV
(Safety Extra Low Voltage) circuits.
The incorporation of the disc drives listed in this guide into a
customer enclosure must meet the appropriate safety requirements of
the country in which it is used (e.g. UL 1950, CAN/CSA-C22.2 No. 950-
M89, DIN VDE 0805/05.90 and EN 60950:1988 (IEC 950).
Low Level formatting
--------------------
All ST3600 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.
Partitioning and high level formatting
--------------------------------------
A drive can be sub-divided into "partitions" which behave as
individual drives within the system.
Read/Write head auto-park
-------------------------
Seagate disc drives described herein mentioned in this drive park the
heads automatically at power off. This feature requires no operator
intervention.
Write precompensation and reduced write current
-----------------------------------------------
Not required on Seagate SCSI or AT (IDE) interface drives covered by
this manual.
SCSI interface drives
---------------------
The SCSI interface handles both drive geometry and defect management
internally. In AT systems a drive type of zero, or 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 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 partiioning, and
FORMAT for high-level formatting.
AT (IDE) interface drives
-------------------------
Seagate AT interface drives mimic (translate) other drive geometries.
If none of the drive types offered by the CMOS supports the number of
heads, cylinders and sectors shown by the table, and your system
does not support a "user-defined" drive type, then select a drive
type in your system CMOS with a capacity which is less than or
equal to the capacity given in the "MBytes" section of the table.
Model MBytes (F) Cylinders R/W Heads Sectors/Track
ST3600A 528 1024 16 63
ST3500A 426 895 15 62
When specifying drive geometry to the systems CMOS different values
may be used for the Cylinders, Read/Write Heads and Sectors/Track
than those given below. However, the final drive capacity shown by
the CMOS cannot exceed the capacity shown in the MBytes column of the
table.
If your BIOS offers a "custom drive" or a "user-defined" drive type,
use one of the configurations listed in the previous table.
The CMOS calculation of drive capacity is based on a variation of the
number of bits in a megabyte, for purposes related to hexadecimal
addressing. When the drive geometry has been entered into the "user
defined" or "custom" drive type. This number should correspond with
the capacity listed in the MBytes column of the table.
Note that the drive will provide the user with full capacity as
specified in the MBytes (F) column of the table. The drive capacity
can be verified by using the CHKDSK utility provided with DOS after
the high-level formatting has been completed.
