 Jumper Setting
 ==============


 Setting the SCSI Bus Address
 ----------------------------
 There are four jumpers available for configuration of the SCSI ID:
 OE1, OE2, OE3 and OE4 on header J6.

 The 68-pin unified connector also has a standard 2mm pitch auxiliary
 header J5, which includes pins to allow remote selection of SCSI IDs.
 A receptable connector AMP P/N 1-111623-7 or equivalent can be used
 to connect a ribbon cable to this header.


 Setting the SCSI ID
 -------------------
  +-------+----------+----------+----------+----------+

   Open means open circuit or high impedance. Ground means
   TTL logic low or logic ground. The active signals are on
   the even numberd pins.


 Disabling Spin-Up at Power On
 -----------------------------
 A jumper in the J7:E5 location, disables spin up after power-on for
 applications where spin up sequencing is necessary. Disabling spin up
 on application of power can also be enabled by setting the DSPN bit
 in MODE SELECT page 00H (Operating Parameters). The Host must issue a
 Start UNIT command to cause the drive to spin up.
   +---------+------+---------------------+
   |  J7:E5  | DSPN | Result              |
   +---------+------+---------------------+
   |   IN    |  0   | Spin Disabled       |
   +---------+------+---------------------+
   |   IN    |  1   | Spin Disabled       |
   +---------+------+---------------------+
   |   OUT   |  0   | Spin up on Power On |
   +---------+------+---------------------+
   |   OUT   |  1   | Spin Disabled       |
   +---------+------+---------------------+


 Delaying Spin Up at Power On
 ----------------------------
 A jumper in the J7:E6 location, delays spin up on power-up by the
 value of the drive's SCSI ID multiplied by 4 seconds (i.e. SCSI ID 4
 will delay 16 seconds). Delaying spin up on application of power can
 also be enabled by setting the SDLY bit in MODE SELECT page 00H
 (Operating Parameters).

   +---------+------+---------------------+
   | J7:E6   | SDLY | Result              |
   +---------+------+---------------------+
   |   IN    |  0   | Spin Delayed        |
   +---------+------+---------------------+
   |   IN    |  1   | Spin Delayed        |
   +---------+------+---------------------+
   |   OUT   |  0   | Spin up on Power On |
   +---------+------+---------------------+
   |   OUT   |  1   | Spin Delayed        |
   +---------+------+---------------------+


 Disabling the SCSI Bus Parity
 -----------------------------
 SCSI parity is always enabled in both directions, unless the J7:E7
 Parity disable jumper is installed. Installing the jumper will cause
 the drive to ignore SCSI bus Parity In but it will continue to
 generate SCSI bus parity out.


 Disabling SCSI Bus Terminator Power (TERMPWR)
 ---------------------------------------------
 Power to the on-board terminators is provided by the higher of the
 voltage supplied at Pin #17, 18, 51 & 52, J2 or the voltage level at
 the 5 Volt power input to the drive minus one diode drop. Termination
 Power to external terminators can be supplied by the drive through
 Pin #17, 18, 51 & 52, J2. The TERMPWR line can be disconnected from
 the drive by removing Jumper E8.

   IN      | TERMPWR (J2, Pin #17, 18, 51 & 52) connected to the
           | drive's internal termination power.
 ----------+----------------------------------------------------
   OUT     | TERMPWR (J2, Pin #17, 18, 51 & 52) open circuit.



 Using the J5 Auxiliary Connector
 --------------------------------
 External logic cabled to the J5 connector may be used to control
 certain characteristics of the drive or access signals.

  | 11   | +5V    |  12   | -FAULT  |
  +------+--------+-------+---------+

 -SEL0
 Bit 0 of the binary coded SCSI ID selection input. This signal has a
 value of 0 when it is negated and a value of 1 when it is asserted
 for the purpose of selection or arbitration.

 This signal is latched within 250 msec of the application of valid
 power to the drive or optionally the negation of -RST.

 If SCSI ID SEL0 is intended to be selected, the host must provide a
 low impedance connection from -SEL(0) to -XTFALT or to ground, while
 the ID is being latched, through an appropriate means.

 -XTFAULT
 This signal is intended to drive an LED to indicate and external
 fault condition has occurred. This signal is held asserted following
 the application of power or optionally the negation of -RST during
 initialization while the SCSI ID is being read. This signal is not
 supported but meets the requirements of negating the signal while the
 ID is being read.

 -SEL1
 Bit 1 of the binary coded SCSI ID selection input. This signal has a
 value of 0 when it is negated and a value of 2 when it is asserted
 for the purpose of selection or arbitration.

 This signal is latched within 250 msec of the application of valid
 power to the drive or optionally the negation of -RST.

 If SCSI ID SEL1 is intended to be selected, the host must provide a
 low impedance connection from -SEL1 to -VUNIQ or to ground, while
 the ID is being latched, through an appropriate means.

 -VUNIQ
 This signal is an open-collector output available for Vendor Unique
 usage. This signal is not supported but meets the requirement of
 negating the signal while the ID is being read.

 -SEL2
 Bit 2 of the binary coded SCSI ID selection input. This signal has a
 value of 0 when it is negated and a value of 4 when it is asserted
 for the purpose of selection or arbitration.

 This signal is latched within 250 msec of the application of valid
 power to the drive or optionally the negation of -RST.

 If SCSI ID SEL2 is intended to be selected, the host must provide a
 low impedance connection from -SEL2 to -SPSYNC or to ground, while
 the ID is being latched, through an appropriate means.

 -SPSYNC
 This signal used to provide a spindle rotation synchronization re-
 ference. This drive does not support spindle synchronization.

 This signal meets the requirement of negating the signal while the ID
 is being read.

 -SEL3
 Bit 3 of the binary coded SCSI ID selection input. This signal has a
 value of 0 when it is negated and a value of 8 when it is asserted
 for the purpose of selection or arbitration.

 This signal is latched within 250 msec of the application of valid
 power to the drive or optionally the negation of -RST.

 If SCSI ID SEL3 is intended to be selected, the host must provide a
 low impedance connection from -SEL3 to -XTACTV or to ground, while
 the ID is being latched, through an appropriate means.

 -XTACTV
 This signal is an open collector output intended to drive an LED to
 indicate the device is active. This signal is negated while the SCSI
 ID is being read.

 -GROUND
 This signal is connected to the drive's logic ground.

 +5 Volts
 This signal provides 5 volts of DC power to drive LEDs and is current
 limited by a 120 ohm resistor.

 -FAULT
 The assertion of this signal will cause the drive to stop any media-
 altering activity, which may result in the drive asserting -XTFALT or
 -VUNIQ, or both. This signal is intended to be used as a power
 failure warning and/or as a write protect input. This signal is not
 supported by this drive.


 Setting the Bus Termination
 ---------------------------
 All SCSI bus signals are common among all devices connected to the
 bus. All signal lines must be terminated at both ends of the bus with
 a terminator. The termination points define the end of the bus. This
 drive does not provide internal termination capability.

 Notes on Installation
 =====================

 Mounting the Drive
 ------------------
 The drive is designed to be used in applications where the unit may
 experience shock and vibrations at greater levels than larger and
 heavier disk drives will tolerate.

 The design features which allow greater shock tolerance are the use
 of rugged heads and media, a dedicated landing zone, closed loop
 servo positioning and specially designed motor and actuator
 assemblies.

 Six side, or four bottom base mounting points are provided to the
 customer. The drive is mounted using 6-32 UNC -2B X 0.16 maximum
 insertion length screws.


 Attaching Power to the Drive
 ----------------------------
 The drive has a 4-pin DC power connector, J4 which is part of the
 Unified Connector, mounted on the PCB. The recommended mating
 connector is AMP part number 1-480424-0 utilizing AMP pins, part
 number 350078-4 or equivalent.


 SCSI Bus Cable
 --------------
 The cable should meet the following guidelines, particulary with FAST
 SCSI-2 systems:

 - Do not route the data cable next to the drive PCB or any other high
   frequency or large current switching signals. Improper drive opera-
   tion can result from improper cable routing.

 - Cable stubs should not exceed 0.2 meter (8 inches).

 - There should be 0.3 meters (12 inches) of cable between drives.

 - The total cable length should not exceed 25 meters (82 feet) and
   may have to be reduced if a mixture of round and flat cable are
   used.

 - Do not tightly bundle excess flat cable against each other since
   this promotes cross coupling of signals on the cable. Use spacers
   to maintain a minimum of 0.050 inches (1.27mm) gap between cable
   runs.

 - Do not clamp the cable tightly against a metal chassis since this
   will degrade the signal. Use spacers or a non-flammable insulation
   material to maintain a gap between the chassis and the cable.


 Mixing Wide and Narrow SCSI Devices on a SCSI Bus
 -------------------------------------------------
 It may sometimes be desirable to attach Narrow Differential SCSI
 devices such as tape backup devices or CDROMs to the same SCSI Host
 Bus Adapter being used to control Wide Differential SCSI devices.
 Intermixing of both Wide and Narrow Differential SCSI devices on the
 same bus required special considerations:

 - The Narrow Differential SCSI devices must be placed at the physical
   end of the bus.

 - The high byte of the SCSI data bus must be terminated at the
   transition adapter from the 34-pair wire to the 25-pair wire.

 - The cable impedance of the 34-pair wire and the 25-pair wire should
   be as closely matched as possible.

 - The 68-pair cable with 30 AWG wire uses four wires to carry
   TERMPWR, which must be joined to wire 26 of the 25-pair wire, if
   terminator power has to be carried over the cable.

 -----------
 All SCSI bus signals are common among all devices conected to the
 bus and the signal lines must be terminated at both ends of the bus
 with a terminator. The termination points define the end of the bus.
 This drive does not provide internal termination capability.


 External Terminator Power
 -------------------------
 Termination Power to external terminators can be supplied by the
 drive through Pin #17, 18, 51, & 52, J2. The TERMPWR line can be
 disconnected from the drive by removing Jumper E8. The following
 table describes the electrical characteristics of the TERMPWR line
 when it is used to supply power to an external terminator.

 TERMPWR Electrical Output Characteristics

 Signal Characteristic             | Value
 ----------------------------------+-------------------------------
 Supply voltage                    | 4.06 VDC to 4.56 VDC
                                   | (dependent on power supplied to
                                   | the drive)
 Minimum source capability         | 1000 mA


 Internal Termination
 --------------------
 The CP4207WD does not provide on-board termination.


 External Termination
 --------------------
 All assigned signals (except TERMPWR, RESERVED and GROUND) must be
 terminated at each ed of the bus with a terminator network. The
 Resistor tolerances in the terminator network must be  5% or less.
 The characteristic impedance of differential terminators is 122 ohms.

 Overview of the Drives
 ----------------------
 The CFP4207 series is a family of high performance 3.5-inch 4.2GB
 (formatted) disk drives. They all offer 9 millisecond average seek
 time for Reading, 9.5 millisecond seek time for Writing, with an
 average latency of only 4.17ms. High capacity is achieved by
 utilizing a zone density recording technique using 15 recording
 zones at an areal density of 317 Mbits per square inch. These drives
 feature high performance while maintaining low power consumption to
 reduce power supply current and system cooling requirements in disk
 arrays.

 They are designed to operate on the Small Computer System Interface
 (SCSI) and are SCSI-2/3 command compatible. The mechanical and major
 electronic components are identical between the models and differ
 only in the host interface implementation.


 Firmware
 --------
 The drive's firmware can be considered in two parts. The first part
 principally reside in the ROM for the 68HC16 background processor.
 This processor is responsible for:

 - starting the spindle motor and maintaining precise rotational speed

 - controlling track following and actuator motion during seeking

 - managing background R/W activity

 - power management

 - monitoring the overall health of the drive.

 The interface processor's control microcode resides in both ROM and
 RAM. The RAM portion of the microcode can be upgraded in the field
 with using software. The interface processor firmware functions
 include:

 - reporting drive status and error conditions to the host

 - manage operating parameters for the drive

 - parsing the Command Descriptor Block and checking for illegal
   fields

 - converting the LBA to CHS and initiating read and write operations
   to the background processor

 - defect management

 - serial port communications

 Since parsing/decoding of commands and execution of the Read/Write
 functions are handled by separate processors, command execution can
 be overlapped in multiple initiator or Tagged Command Queuing
 environments. Functions such as seek re-ordering and command coalesc-
 ing can also be overlapped when the drive is operating with a host
 environment capable of supporting Tagged Command Queuing.

       |Latency                msec. avg. |   4.17 |
       +----------------------------------+--------+


 Error Correction
 ----------------
 The drive uses a three way interleaved 96-bit Reed-Solomon code to
 perform error correction. An additional 48-bit Cyclic Redundancy
 Code (CRC) provides additional miscorrection detection. For each
 512-byte block, the on-the-fly error correction polynominal is
 capable of correcting:

 - one error burst of up to 41 bits in length

 - two error bursts each up to 17 bits in length

 The miscorrection probability is less than 1 bit in 10(24) bits
 transfered.


 Read/Write Heads and Disks
 --------------------------
 Data is recorded on 95mm diameter disks trough 3370-type 50% nano-
 slider thin film heads with transverse pressure contour (TPC) air
 bearing surfaces. The TPC air bearing surface allows the head to
 fly at a uniform height regardless of radial position. This improves
 data reliability and allows the serial density to be more uniform
 with radius. The CFP4207 series contains the sputterd thin film
 disks with twenty data surfaces and twenty read/write heads.

 At power-down, the heads are automatically retracted to the inner
 diameter of the disk and are latched and parked on a landing zone
 that is inside the data tracks.


 Head Positioning System
 -----------------------
 The read/write heads are supported by a mechanism coupled to a
 rotary voice coil actuator.


 Drive Motor and Spindle
 -----------------------
 A brushless DC direct-drive motor assembly is mounted on the drive's
 base. The motor rotates the drive's spindle at 7200 RPM. The motor/
 spindle assembly is dynamically balanced to provide minimal
 mechanical runout to the disks. A dynamic brake is used to provide
 a fast stop to the spindle motor and return the heads to the landing
 zone when power is removed.


 Safety Standards
 ----------------
 The drive is designed to comply with relevant product safety
 standards, including:

 - UL 478, 5th edition, Standard for Safety of Information Processing
   and Business Equipment

 - UL 1950, Standard for Safety of Information Technology Equipment

 - CSA 22.2#220, Information Processing and Business Equipment
