 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.

 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   |

   |    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 |

   |  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).

     +-----J2-----+   pin 1  +12 VDC   5% AT 4.5A max. (power-up  10%)

   --+------------+-  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.
