 The drive will operate in all axis (6 directions).


 Mounting
 --------
 The drive can be mounted in the following positions listed below.

 - Top Side Down

 - Bottom Side Down

 - Right Side Down

 - Left Side Down

 - Rear Side Down

 Four mounting holes are provided on the bottom of the drive, and two
 mounting holes are provided on each side of the drive.

 The torque applied to the mounting screws must be 1.0 Newton-meters
   0.1 Newton-meters.

 WARNING
 The file's mounting frame is electrically isolated from the file's
 disk enclosure. The disk enclosure is not at ground potential. There-
 fore any user mounting scheme must not result in the disk enclosure
 being shorted to ground.


 Clearances
 ----------
 A minimum of 2mm clearance should be given to the bottom surface
 except at the bottom mounting holes. For proper cooling it is
 suggested that a clearance of 6mm be provided under the dile and on
 top of the file.

 NOTE
 Precaution must be taken so as not to block any vent holes on the
 side of the file.

 NOTE
 The top of the drive will not exceed the height dimension by more
 than 2 millimeters during a 35 G 20 millisecond drop.


 Mounting Hole Notes
 -------------------
 1. Maximum allowable penetration of noted screw to be 3.8 mm.

 2. Area defined by the noted dimensions requires a minimum of 2 mm
    clearance, excluding a 10 mm diameter area around the bottom
    mounting holes.


 Power Connector
 ---------------
 The DC power connector is designed to mate with a Molex 8981-4P4
 crimp connector, or a Molex A-70156-2000 insulated displacement
 connector, or their equivalent.

                    pin 4    + 5 VDC


 50-Pin SCSI Bus Connector
 -------------------------
 The SCSI signal connector is a 50-pin connector, MOLEX p/n 70246
 meeting ANSI/SCSI specification.


 SCSI Cable
 ----------
 The 0663 disk drive uses single-ended drivers and receivers which
 will permit cable lengths of up to 6 meters (19.68 feet).

 For a single-ended cabe a 50 conductor flat cable or a 25 signal
 twisted cable can be used with a maximum length of 6.0 meters, and a
 stub length not to exceed 0.1 meters.

 This file has a maximum internal stub length of 0.072 meters on all
 SCSI signals except -RST; the -RST signal has an internal stub length
 of 0.096 meters. To remain compliant with ANSI, the SCSI bus cable
 must not add more than 0.028 meters additional stub length to all
 SCSI signals except -RST, and no more than 0.004 meters additional
 stub length to -RST.


 SCSI Bus Terminators
 --------------------
 The file has no internal SCSI bus terminators. The user is
 responsible for properly terminating and powering the SCSI bus in the
 using system.

 DATA MATE DM500-06-0 or equivalent external terminator may be used
 for termination of the file.


 SCSI Bus Electrical Characteristics

 Control Electronics
 -------------------
 The drive is electronically controlled by an interface micro-
 processor, a servo control microprocessor, several logic modules,
 digital/analog converters, and various drivers and receivers. The
 control electronics performs the following major functions:

 Servo Microprocessor
 --------------------
 - Conducts a power-up sequence and calibrates the servo
 - Monitors various timers for head settle, servo failure, etc.
 - Issues signals to control accessing servo signal gating, recali-
   brating, track following, or error recovery (dependent on appro-
   priate input conditions).
 - Analyzes servo signals to provide closed loop control. These in-
   clude position error signal and estimated velocity.
 - Controls the voice coil motor power amplifier driver to drive the
   actuator to a desired position.
 - Constantly monitors error conditions of the servo and takes corres-
   ponding action if an error occurs.
 - Stores/Provides/Controls the velocity profile for the servo.
 - Monitors the actuator position and determines the target track for
   a seek operation.
 - Monitors the spindle speed during operation.

 Interface Microprocessor
 ------------------------
 - Controls and interprets all interface signals between the host
   controller and the drive.
 - Controls starting, stopping, and monitoring of the spindle.
 - Controls read/write accessing of the disk media, including defect
   management and error recovery.
 - Performs self-checkout (diagnostics)

 ECC Implementation: A Reed-Solomon Error Correcting Code of degree 5
 with 3-way interleaving is used to cover the data fields.


 Head/Disk/Spindle Assembly
 --------------------------
 The head and disk assembly (HDA) is assembled in a clean environment
 and contains the disks and actuator assembly. Air is constantly
 circulated and filtered when the drive is operational. Venting of the
 HDA is accomplished via an absolute breather filter.

 The HDA is shock mounted to minimize transmission of vibration
 through the chassis.

 The spindle is driven directly by an in-hub, brushless DC driver
 motor. The motor is dynamically balanced to ensure a low level of
 vibration. Dynamic braking is used to quickly stop the spindle.


 Actuator
 --------
 The read/write heads are mounted on the actuator. The actuator is a
 swing-arm assembly driven by a voice coil motor. A closed-loop
 positioning servo controls the movement of the actuator. A dedicated
 servo surface and head supplies feedback to the positioning servo to
 keep the read/write heads centered over the desired track. During
 seeks, the servo head provides track crossing information to the
 servo.

 The actuator assembly is balanced to allow vertical or horizontal
 mounting without adjustment.

 When the unit is stopped (via a SCSI command or power off condition)
 the actuator automatically moves the heads to a dedicated landing
 zone outside of the data area, where the actuator is locked.


 Hot plug/unplug support
 -----------------------
 If there is a need to plug or unplug the file while the power is
 active then the using system must assure that the ground pin makes
 contact first. This prevent a possible CMOS latch-up condition.
 During the hot "plug-in" event the 5 or 12 volt power supply voltage
 must not go out of tolerance in the high voltage direction. During
 the hot "unplug" event capacitors on the file will prevent inductive
 flyback voltages from increasing to the point of damage to the file.

 If the SCSI bus is connected while it has power active on any of it's
 lines then a power or signal glitch may occur on the bus. If any
 other devices are sharing the bus then this glitch may cause them to
 produce an error.

IBM       SCSI INSTALLATION

 SCSI Installation Guide Generic

 Installation requirements
 -------------------------
 To install a drive inside your computer or in an external storage
 enclosure for SCSI devices, you must have:

 1 The documentation that came with your computer or storage
   enclosure.

 2 The documentation that came with your hard drive.

 3 A small, flat blade screwdriver.

 4 A SCSI controller, which is either built into the system board or
   on an adapter inside your computer.

 5 An installation kit, if it is required for your computer. Contact
   your place of purchase if you are not sure.

 6 If you are installing this into a PS/2 computer, you will also need
   the up-to-date backup copy of your reference diskette and
   diagnostic diskette.

 WARNING: Do not open the static-protective bag containing the drive
 until instructed to do so. Static electricity can damage the drive.


 Hardware and software considerations
 Operating system
 ----------------
 The operating system and hardware are two of the factors that
 determine the number of drives a computer can support. The manuals
 for your computer and operating system can help you to determine the
 number and type of hard disk drives you can use.


 Power supply
 ------------
 Two factors that determine the number of internal drives that a
 computer or SCSI storage enclosure can support are:

 1 The available current of the power supply

 2 The nominal operating current of each drive installed

 Most computer power supplies have output over-current protection. If
 the total allowed current is exceeded, the power supply shuts down.
 The computer must be turned off and turned on again.

 SCSI ID Each SCSI device connected to a SCSI adapter must be assigned
 a unique SCSI identification number (ID). The ID you assign to this
 device depends on the number of SCSI devices connected to the SCSI
 adapter and the SCSI IDs already assigned to those devices.

 Note: All IBM SCSI controllers support SCSI IDs 6 through 0. (ID 7 is
 used for the SCSI controller.) Some SCSI controllers support SCSI IDs
 15 through 8. If your SCSI controller supports more than seven
 devices, then you can use SCSI IDs 15 through 8. If you are not sure
 if your SCSI controller supports more than seven devices, refer to
 the documentation that came with your SCSI controller for
 information.

 If you have an IBM PS/2 computer, you can view your SCSI ID settings
 by accessing the system programs. From the main menu, select Set
 configuration. The select Set and view SCSI configuration.
 Other computers might have utility programs that enable you to view
 the SCSI configuration, or you might have to physically inspect the
 installed SCSI devices to see how the IDs are set. For more
 information, refer to the documentation that came with your computer
 or SCSI controller.


 Handling precautions
 --------------------
 1 Turn off all attached devices first; then turn off the computer.

 2 Unplug all the power cords from electrical outlets before starting
   installation.

 3 Disconnect all power cables from your computer and attached devices
   before starting installation.

 4 Limit your movement. Movement can cause static electricity to build
   up around you.

 5 Handle the drive carefully and by the edges.

 6 Do not touch any exposed printed circuitry.

 7 Prevent other people from touching the components or the drive.

 8 When you are installing the drive, touch the static-protective
   package containing the drive to a metal expansion-slot screw or
   other unpainted metal surface on the computer, for at least 2
   seconds. (This drains static electricity from the package and your
   body.)

 9 When possible, remove the drive and install it directly into the
   computer without setting it down. If this is not possible, place
   the drive, component side up, on the static-protective bag on a
   flat surface until the drive is installed.

 10 Do not place the drive on the computer cover or on a metal table.


 Installing the drive
 --------------------
 These instructions guide you as you install the drive inside your
 computer or storage enclosure.

 Step 1. Setting the jumpers and terminators

 Note: Be sure you have chosen the SCSI ID before continuing. If you
       did not yet choose the SCSI ID, go to "SCSI IDs" above, then
       return here. Follow these steps to set the SCSI ID to match
       your chosen SCSI ID.

 1 Touch the static-protective bag containing the drive to a metal
   expansionslot cover on the computer. This drains any static
   electricity from the package and your body.

 2 Remove the drive from the static-protective bag, holding the drive
   by the edges. Do not touch any exposed components on the drive.

 3 Place the drive on the bag, on a flat surface.

 4 When the Auto Start feature is enabled, the hard disk drive motor
   starts as soon as the computer is turned on. Locate the Auto Start
   jumper by referring to the documentation that came with your drive.
   If the Auto Start jumper is not in place, the hard disk is started
   by a command from the SCSI controller. For drives installed in
   IBM computers or storage enclosures ensure that this jumper is off.
   The hard disk drive is started in a staggered sequence. This
   reduces the start-up load on the power supply. For non-IBM
   computer, refer to the documentation that came with your
   computer for further information.

 5 Set the SCSI ID that you selected. To remove a jumper, pull it
   straight off. To install a jumper, line up the two holes in the
   jumper with the appropriate two pins on the drive. Then push the
   jumper onto the pins until it is completely seated and covers
   both pins.

 6 Store any jumpers you do not use in a safe place, in case you need
   to change the SCSI ID for this drive later. WARNING: If you have
   extra jumpers, do not store them on any of the extra pins on the
   connector. Storing them on a set of pins could damage the drive.

 Step 2. Connecting the terminator
 The location of the drive you are installing inside the computer or
 storage enclosure determines whether you need to connect a terminator
 or put a jumper on the Enable Active Termination pins. Read the
 information in the following table to determine if you must install
 the terminator. For more information about termination, refer to the
 documentation that came with your computer.

 Note: A SCSI chain of devices consists of multiple SCSI devices
 connected by a SCSI cable to a SCSI controller.

 If the hard disk drive is:                   Then:
 The last physical device on a SCSI chain of  Install the terminator
 devices inside the computer.

 The last physical device on a SCSI chain of  Install the terminator
 devices inside an external storage enclosure.

 Step 3. Enabling term power
 If your drive has a jumper for term power and your SCSI controller is
 suppling term power, (check with the manufacturer of your controller)
 then you do not need to enable the term power. The jumper should be
 off. For help in locating the term power jumper, refer to the
 documentation that came with your drive.

 Step 4. Installing the drive
 For the specific information on installing a hard disk drive, refer
 to the documentation that came with your computer. You will be
 required to mount the drive inside your computer, and connect signal
 and power cables to the hard drive. When installed in an enclosure,
 the drive is attached by cable to the external connector of a SCSI
 controller. The controller can be either on a SCSI adapter or built
 into the system board inside of your computer.

 Note: Be sure to use the correct screws provided with your drive.
 Using the wrong ones might cause damage to the drive.

 Step 5. Completing the installation procedure
 The installation of the drive is complete. Reinstall the cover on the

 1 The cables are installed correctly

 2 No options or cables are loose

 3 The SCSI ID is properly set

 5 The terminators are properly installed

 Turn on all attached devices; then, turn on the computer. If you
 still have a problem, refer to the troubleshooting information in the
 documentation that came with your computer.

 Step 6. Update configuration
 Whenever you add or remove an option from your computer, you must
 update the configuration information. Your computer might have an
 automatic configuration program, or you might have to follow a
 specific procedure. For more information, refer to the documentation
 that came with your computer.

 Step 7. Preparing the drive for use
 Having successfully installed the hard disk drive, you need to
 prepare it for use. Depending on the operating system you are using,
 you might need to partition then format the hard disk. Refer to the
 documentation that came with your operating system for information on
 how to format your new drive. To make the drive just installed your
 primary drive, you might need to create a new system partition on the
 drive. For information on creating a new system partition, refer to
 the documentation that came with your operating system.
