ORCA OT512-S INSTALLATION MANUAL P/N 308120, JANUARY 17, 1992
Jumper Setting
==============
x = Factory default
The drive contains user selectable and factory select jumpers. The
factory select jumpers must be placed in the default position
specified for proper operation of the drive. Jumpers are read only
during initialization of the drive. If the jumper settings are
changed, the drive must be reset by powering it down or by issuing a
bus device reset command before the new settings will take effect.

User Jumpers
------------
The user selectable jumpers are defined below:
Remote Settings - J4/J5 - The Remote Settings are two groups of
jumpers that may be jumpered on the drive PCB or cabled to a remote
location for selection by the user.
Terminator Power - If jumper W5 is installed the drive will source/
receive terminator power to/from the SCSI bus.
Hard/Soft SCSI Reset - If jumper W6 is installed the hard reset SCSI
option is selected.
Enable Look Ahead Read - If jumper W8 is installed the look ahead
read option is enabled.
Enable Power On Sequence Up - If W10 is installed the drive will
automatically sequence up when power is applied. If W10 is not
installed the drive will require a Sequence Up command before the
drive will be spun up.

or externally via a 12-pin connector and cable (not provided).

SCSI ID Jumpers
---------------
Every peripheral device that is connected to the SCSI bus must have a
unique address (SCSI device ID). The disk drive SCSI ID is selected
by installing jumpers on J4 (1-2, 3-4, 5-6). SCSI ID 0 is the default
jumper selection.
+----------+-----------------------+ | SCSI ID | Jumpers | | | 5-6 | 3-4 | 1-2 | +----------+-------+-------+-------+ |x 0 | OPEN | OPEN | OPEN | | 1 | OPEN | OPEN | CLOSED| | 2 | OPEN | CLOSED| OPEN | | 3 | OPEN | CLOSED| CLOSED| | 4 | CLOSED| OPEN | OPEN | | 5 | CLOSED| OPEN | CLOSED| | 6 | CLOSED| CLOSED| OPEN | | 7 | CLOSED| CLOSED| CLOSED| +----------+-------+-------+-------+
J4 7-8 Disable Auto Sequence Up
--------------------------------
If auto sequence up is enabled (J4 7-8 Not installed), the drive will
delay six seconds after power is applied (multiplied by its SCSI ID)
before spin up begins.
J4 9-10 Write Protect
----------------------
Connecting J4-9 with a jumper to J4-10 will inhibit writing and
protect all previously written data.
Remote Ready
------------
This line may be used to operate a remote LED.
+5 Volts -------- This is five volts from the drive.
Block Size
----------
The block size can be selected through the Mode Select command or by
the jumper selection.
Block Size Jumpers +--------+--------+-----------------+ | J5 3-4 | J5 1-2 | Block Size | +--------+--------+-----------------+ | Out | Out | Via Mode Select | | Out | In | 256 bytes | | In | Out | 512 bytes | | In | In | 1024 bytes | +--------+--------+-----------------+
Disable Unit Attention
----------------------
Connecting J5-5 and J5-6 will disable the generation of Unit Atten-
tion after device reset.
Disable SCSI Bus Parity
-----------------------
Connection J5-7 and J5-8 will disable the checking of SCSI bus
parity.
Factory Jumpers
---------------
The factory use jumpers must be placed in the default position
specified for proper operation of the disk drive.
RP6/RP7 Termination
--------------------
The ORCA drive is shipped with a terminator installed to minimize
reflections and ensure maximum data integrity. In a daisy chain
configuration the first SCSI device and the last SCSI device must be
terminated. Other terminators must be removed. The OT512-S drive
will supply terminator power to the SCSI bus if jumper W5 is
installed. If a terminated drive loses power, terminator power will
be received through W5, if supplied by another SCSI device.
J6 Front Panel Interface (LED)
-------------------------------
The front panel indicator is a green LED that illuminates when the
drive is selected. It is connected via a internal cable to front
panel connector J6 on the bottom side of the PCBA. The front panel
(bezel) with LED and cable are an OPTION.

Notes on Installation
=====================
Drive Mounting Dimensions
-------------------------
Side mounting screws must not extend more than 1/16 inch past the
inside of the frame.
The drive may be mounted in any orientation using the industry
standard mounting configuration.
Sway space/ventilation clearance in the Z axis (through the spindle)
of .030" must be provided.
Drive Handling Guidelines
-------------------------
Do not drop the drive from any height. Set the drive down carefully
on a padded surface.
Carts used to transport drives should have soft rubber wheels to ab-
sorb shock. Foam pads should be placed under drives when transport-
ing.
Store and transport drives right-side up (long dimension horitontal
or flat, top up, and drive motor down). Drive must rest on a flat
surface. Do not put papers, etc. under the drive.
Do not dress or reposition components, wires, or cables.
Do not place drives in vertical position closer than two to three
inches apart to avoid hitting and breaking components.
Do not remove seals from the Head/Disk Assembly. This will result in
contamination which affects drive operation. Do not attempt to
disassemble the Head/Disk Assembly.
Do not place objects on top of the drive (especially metallic
objects).
Do not store the drive where a possibility exists of condensation
from humid air.
Shock and Vibration Precautions
-------------------------------
The drives must be handled in such a manner so as not to exceed the
Non-Operating and Installed, or Unpacked and Stored environmental
specifications.
Automatic Head Actuator Lock
----------------------------
This automatic lock requires no action by the user. When the drive is
powered down, the actuator locks onto a designated landing zone to
prevent head/media damage when shipped and handled according to
specifications.
Cable Connections
-----------------
The interface cables may not exceed six meters (19.7 ft.)
J2 DC Power
-----------
The drive power connector is a 4-pin connector, mounted on the
component side of the PCBA. The recommended mating connector is AMP
P/N 1-480424-0, utilizing AMP pins P/N 61314-4 (Strip) or P/N 60617-4
(Loose Piece).

--+------------+- pin 3 + 5 Volts Return
------------------- pin 4 + 5 VDC 5% AT 2.5A max.
J3 SCSI Interface
-----------------
J3 is a 50-pin right-angle socket header. The pins are numbered 1
through 50 with the odd pins located closest to the PCB. All odd
numbered pins are ground except pin 25, which is left open. It
receives a 50-pin flat cable socket connector. The recommended mating
connector is 3M O/N 3425-7050 or SAE RD6350-R5C.
