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.

+----+---------------TP--+ \ Position A
Position 2
1 Enable Terminators [2]
With the jumper installed, the On-board (non-removable)
terminator circuits are enabled (connected to the I/O lines).
Default is jumper installed.
With the jumper NOT installed Terminator circuits are
disabled.
2 Jumper installed in position 2 enables the Delayed Motor
Start option (if jumper in position 3 is off). Motor start
delays is 16 times the drive ID number in seconds; i.e. drive
ID 0 starts immediately. Drive one starts 16 seconds later,
etc.
3 Jumper installed enables Motor Start option. The drive waits
for the Start unit command from the host before starting the
spindle motor. If no jumper is installed, drive operation de-
pends on whetheror not there is a jumper in position 2.
If jumpers 2 and 3 are both off, drive spins up with no delay
when power is applied.
Jumper 2 and 3 are installed
Drive spindle starts when Start Unit command received from
host. Delayed start feature is overridden and does not apply
when jumper 3 is installed.
4 Jumper installed means entire drive is write protected.
Jumper NOT installed means write protect is disabled
(default).
5 Jumper installed means parity checking by the drive is
enabled.
Jumper NOT installed
Drive does not report result of parity checking to host.
Default is jumper 5 installed.
6 RESERVED! Default is no jumper installed.
7/8 Jumper 7 and 8 OFF
No terminator power is connected to drive terminators or
SCSI bus I/O pin 26.
Jumper 7 ON and Jumper 8 OFF
Drive supplies its own terminator power only. Jumper in this
position is factory default for "N" models only.
Jumper 7 OFF and Jumper 8 ON
Drive supplies power to I/O pin 26 of SCSI bus; none to
internal terminators. When drives have differential I/O
circuits, a jumper on jumper 8 position may be needed to
power external terminators. The "ND" model drives have
differential I/O circuits which have no terminator circuits
on the drive.
Jumper 7 ON and Jumper 8 ON
Drive supplies terminator power to itself (internal
connection) and to I/O pin 26 of SCSI bus. This is a legal
jumper setting.
Position A ON
This horizontally positioned jumper across the two TP
positions nearest PCB edge, connects terminator power from
SCSI bus I/O pin 2 to the drive's internal termination.
OFF
See above explanations for jumper 7 and 8.
[2] "ND" models do not have terminators on the drive PCB, so these
jumpers are not applicable on those drives.

1,2,3 Either J5 or J6 (optional) may be used to select drive ID.
Both should not be used at same time, because at some future
time, settings may be changed, causing the drive to not
respond correctly. The factory installs no ID jumpers on J5 or
J6 (drive ID 0).
5 These pins used to connect a cable for a remote LED indicator.
Pin 3 (top, nearest HDA), the anode connection, connects in
the drive to the +5V supply through a pullup resistor. Pin 4
(bottom), the cathode connection connects in the drive to
signal common through the emitter-collector junction of a
transistor switch that controls the LED on/off condition.
6 Reserved.
On SCSI I/O drives either J6 (on the front of the drive) or J5 (on
the side behind the DC Power connector) may be used to set the drive
ID. To avoid possible incorrect ID setting, do not use both J5 and
J6 for ID selection.

Disc drive mounting
-------------------
The drive may be mounted in any orientation.
Mount to the host 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 surface of the chassis. The
minimum thread engagement for all mounting screws is .12 inch (3.05
mm). Tighten the screws evenly to a maximum torque of 6 in-lb (.675
NM). Do not over tighten or force when screw does not seem to screw
in easily (threads not correctly engaged).
SCSI interface cable connection
-------------------------------
Models Hawk 4 family are SCSI interface drives. System connection is
via a 50 pin SCSI connector. Some cables have a contrasting color
strip on one edge to indicate pin 1. Strain relief is recommended at
the cable in drives using cables. Do not block system cooling air
flow in routing of cables.
DC Power connection
-------------------
The drives receive DC power through a 4 pin connector mounted on the
PCB next to the SCSI I/O connector.
Bus termination
---------------
Model "N" drives have an active terminator IC that is permanetly
installed, but can be enabled or disabled by a jumper plug. If you
are installing a single drive, the terminator IC must remain
enabled. If you are installing multiple hard disc drives, disable the
termination IC on all the drives but the one connected to the end of
the SCSI I/O cable.
Model numbers that end in "ND" have differential I/O circuits. These
drives have no provisions for terminators on the drive PCB. The
system manufacturer must provide some external means of I/O line
termination. The "ND" model drives can provide power for external
terminators if the TP is installed on the last position on the last
position on the right end of J2.
Grounding
---------
Signal ground (PCB) and HDA ground are connected together in the
Hawk 4 family 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.
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.
Features
SEAGATE ST15230N/ND INSTALLATION GUIDE 77767474 REV. B 10/94
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 interface drives covered by this manual.
SCSI interface 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.
Initial set-up information
--------------------------
For the initial setup connect th ecables or plug into a mounted
connector (if applicable), set the drive ID on the bus and enable
or disable the I/O line terminator IC ("N" models).
