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


 E1/0E1-E3/0E3 SCSI ID
 ---------------------
 There are three jumpers available for configuration of the SCSI ID:
 E1, E2, and E3.

 An optional 2mm pin pitch right angle header is located on the front
 of the PCBA (opposite the SCSI interface connector) which allows
 changing the SCSI IDs while the drive is mounted in the system. The
 header includes three pins, 0E1, 0E2, and 0E3 which can alternatively
 be used to select the SCSI Bus address. This connector may also be
 used to cable the SCSI ID select to a remote switch. A receptacle
 connector AMPO P/N 111622-1 orr equivalent can be used to connect a
 ribbon cable to this header.
   +----------+-----------------------+
   | SCSI ID  |        Jumpers        |
   |          | E3/0E3| E2/0E2| E1/0E1|
   +----------+-------+-------+-------+
   |    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|
   +----------+-------+-------+-------+


 Disabling Spin-Up at Power On
 -----------------------------
 A jumper in the E5 location, disables spin up after power-on for
 applications where spin up sequencing is necessary. An optional 2mm
 pin pitch right angle header is located on the front of the PCBA
 (opposite the SCSI interface connector) which can alternatively be
 used to disable spin up. Disabling spin up on application of power
 can also be enabled by setting the DSPN bit in MODE SELECT page 00H
 (Operating Parameter).
   +---------+------+---------------------+
   |  E5/0E5 | DSPN | Result              |
   +---------+------+---------------------+
   |   IN    |  0   | Spin Disabled       |
   |   IN    |  1   | Spin Disabled       |
   |   OUT   |  0   | Spin up on Power On |
   |   OUT   |  1   | Spin Disabled       |
   +---------+------+---------------------+
 NOTE
 IN = Ground or TTL Low and OUT = Open or TTL High.


 Delaying Spin Up at Power On
 ----------------------------
 A jumper in the 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.)

   +---------+------+---------------------+
   |   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 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 #26, 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 #26,
 J2. The TERMPWR line can be disconnected from the drive by removing
 Jumper E8.


 Jumper E8   Result
   IN        TERMPWR (J2, Pin #26) connected to the drive's internal
             termination power.
   OUT       TERMPWR (J2, Pin #26) open circuit.


 Setting the Bus Termination
 ---------------------------
 This drive provides on-board Alternative 2 active termination for the
 SCSI bus. The termination resistors, which are contained in two
 Single Inline Packs (SIPs) should be removed from the drive unless it
 is a SCSI device at the physical end of the bus.

 NOTE
 The TERMPWR output of the drive is protected by a 1 Ampere fuse (F1).
 If external terminators are being powered from the drive and SCSI bus
 problems are suspected, verify that the fuse is still operational
 using a meter.

   |                 |
   +-----------------+

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


 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.

 Eight 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. The system integrator should allow
 ventilation to the drive to ensure reliable drive operation over the
 operating temperature range. The drive may be mounted in any
 orientation.


 Cabling the Drive CFP-1060D
 ---------------------------
 Connect the SCSI interface cable and the spindle synchronization
 cable (when needed).


 Cabling the Drive CFP-1060E
 ---------------------------
 The drive is intended for direct backplane connection to the SCA
 connector rather than through cabling.


 Attaching Power to the Drive CFP-1060E
 --------------------------------------
 The drive is powered through the SCA connector and is intended for
 direct backplane connection rather than through cabling.


 SCSI Bus Cable CFP-1060S
 --------------------------
 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 0.1 meter (4 inches).
 - There should be 0.3 meters (12 inches) of cable between drives.
 - The total cable length should not exceed 6 meters (20 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.


 SCSI Bus Cable CFP-1060W
 ------------------------
 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 0.1 meter (4 inches).
 - There should be 0.3 meters (12 inches) of cable between drives.
 - The total cable length should not exceed 3 meters (10 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.


 Attaching Power to the Drive CFP-1060S/W
 ----------------------------------------
 The drive has a 4-pin DC power connector, J4 mounted on the PCB. The
 recommended mating connector is AMP part number 1-480424-0 utilizing
 AMP pins, part number 350078-4 or equivalent.


 Mixing Wide and Narrow SCSI Devices on a SCSI Bus
 -------------------------------------------------
 It may sometimes be desirable to attach Narrow SCSI devices such as
 tape backup devices or CDROMs to the same SCSI Host Bus Adapter be-
 ing used to control Wide SCSI devices, such as the CFP-1060W.
 Intermixing of both Wide and Narrow SCSI devices on the same bus
 required special considerations:

 - The Narrow 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.

 Spindle Synchronization
 -----------------------
 The spindle rotation of up to 35 drives may be synchronized together
 by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 on connector J3
 or chaining pin 6 of the 2mm option header J5. The spindles are
 synchronized using a "floating master" concept, where the drives will
 synchronize to the first drive to reach full speed. The
 synchronization tolerance is 1%.


 Output Characteristics
 ----------------------
 The output drivers for Data, Parity, REQ and ACK are optionally
 active negation. When they are set for active negation, they have
 three states: asserted, negated and high impedance. The remainder of
 the signals have open collector (drain) outputs. The drive maintain a
 high impedance state during power-on and power-off cycles. The driven
 signals have the following output characteristics when measured at
 the drive connector:

 Active Negation Driver Output Signal Characteristics

 Signal Characteristic             | Value
 ----------------------------------+----------------------------
 Signal Assertion                  | 0.1 VDC to 0.5 VDC at 48 mA
 Minimum Driver Output Capability  | 48 mA (sinking) at 0.5 VDC
 Signal Negation                   | 2.0 VDC to 3.24 VDC at 7mA
                                   | 3.0 VDC at 20 mA

 Open Collector Driver Output Signal Characteristics

 Signal Characteristic             | Value
 ----------------------------------+----------------------------
 Signal Assertion                  | 0.0 VDC to 0.5 VDC at 45 mA
 Minimum Driver Output Capability  | 48 mA (sinking) at 0.5 VDC
 Signal Negation                   | 2.5 VDC to 5.25 VDC


 Input Characteristics
 ---------------------
 Signal Characteristic             | Value
 ----------------------------------+---------------------------
 Signal Assertion                  | 0.0 VDC to 0.8 VDC
 Signal Negation                   | 2.0 VDC to 5.25 VDC
 Input Load (low level)            | -20  A to 0.0 mA at 0.5 VDC
 Input Load (high level)           | 0.0 mA to 20  A at 2.7 VDC


 External Terminator Power CFP-1060E
 -----------------------------------
 The interface connector carries both power and ground so a separate
 TERMPWR interface line is not provided.


 Internal Termination CFP-1060E
 ------------------------------
 This version of the drive has no on-board termination so the drive
 must be externally terminated. Alternative 2 active termination is
 recommended. Alternative 1 passive termination is not suitable for
 this application.


 Cable Requirements CFP-1060E
 ----------------------------
 This version of the drive is designed to interface directly a mating
 connector which is on a passive back plane or directly into a
 motherboard. The same guidelines relative to impedance, stub length
 and distance between stubs apply for SCSI bus signal reliability.
 These guidelines may not be directly translated to a back plane
 design so these design rules are to eb viewed with respect to the
 intended purpose of controlling reflections and the propagation of
 signals down the bus. Since the characteristics for PCB signal traces
 are affected by trace width, proximity to ground, and trace routing,
 careful review of the back plane design and analysis of signal
 quality is highly recommended.


 Connector Requirements CFP-1060E
 --------------------------------
 The drive's connector will mate with a AMP Champ 2-557103-2 vertical
 receptacle or the AMP Champ 2-557101-1 right angle receptacle.


 Single Connector Attachment (SCA) Signal Definitions
 ----------------------------------------------------
 Power
 Four +12 Volt signals provide the +12 volt power to the drive. The
 current return for the +12 volt power is through the +12 Volt Ground
 signals. The maximum current that can be provided to the drive
 through the +12 Volt signal pins is 3 Amperes. The supply current and
 return current must be distributed as evenly as possible among the
 pins. The maximum current is while the drive motor is starting.

 Three +5 Volt signal pins provide +5 volt power to the drive. The
 current return for the +5 volt power is through the +5 Volt Ground
 pins. It is expected that the +5 Volt Ground will also establish the
 digital logic ground for the drive. The maximum current that can be
 provided to the drive through the +5 Volt signal pins is 2 Amperes.
 The supply current and return current must be distributed as evenly
 as possible among the pins.


 Spindle Sync CFP-1060E
 ----------------------
 The spindle rotation of up to 35 drives may be synchronized together
 by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 of each drive
 on connector J3. The spindles are synchronized using a "floating
 master" concept, where the drives will synchronize to the first drive
 to reach full speed. The synchronization tolerance is 1%.


 LED Out CFP-1060E
 -----------------
 The LED out signal is driven by the drive when the drive is perform-
 ing a SCSI operation. The LED out signal is designed to pull down the
 cathode of an LED. The anode is attached to the proper +5 volt supply
 through an appropriate current limiting resistor. The LED and the
 current limiting resistor are external to the drive.


 External Termination Power CFP-1060S
 ------------------------------------
 Power to the on-board terminators is provided by the higher of the
 voltage supplied at Pin #26, J2 or the voltage level at the 5 Volt
 power input to the drive minus one diode drop. The diode prevents
 back flow of current to the drive. Termination Power to external
 terminators can be supplied by the drive through pin 26, J2. The
 TERMPWR line can be disconnected from the drive by removing Jumper
 E8.


 Internal Termination CFP-1060S
 ------------------------------
 This drive provides on-board Alternative 2 active termination for the
 SCSI bus. The termination resistors, which are contained in two
 Single Inline Packs (SIPs) should be removed from the drive unless it
 is a SCSI device at a physical end of the bus.


 Cable Requirements CFP-1060S
 ----------------------------
 A 50 conductor cable no more than 6 meters (19.68 feet) cumulative
 length with at least 28 AWG wire size and a characteristic impedance
 of 70 to 100 ohms (84 ohms nominal) is required.


 Connector Requirements CFP-1060S
 --------------------------------
 The connector on the drive is a 50-position header which consists of
 2 rows of 25 male pins on 0.100 inch centers. The mating connector is
 a SCSI-2 Non-shielded Alternative 1, A-cable connector.


 External Terminator Power CFP-1060W
 -----------------------------------
 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 1 diode drop. The diode
 prevents back flow of current to the drive. 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.


 Internal Termination CFP-1060W
 ------------------------------
 This drive provides on-board Alternative 2 active termination for the
 SCSI bus. The termination resistors, which are contained in three
 Single Inline PAcks (Sips) should be removed from the drive unless it
 is a SCSI device at a physical end of the bus.


 Cable Requirements CFP-1060W
 ----------------------------
 A 68 conductor cable no more than 3 meters (9.84 feet) cumulative
 length with at least 30 AWG wire size and a characteristic impedance
 of 70 to 100 ohms (84 ohms nominal) is required.


 Connector Requirements CFP-1060W
 --------------------------------
 The connector on the drive is a 68-pin. The mating connector is a
 SCSI 3 Non-shielded P-cable connector.

 Overview of the Drives
 ----------------------
 The CFP1060 series are a family of high performance 3.5-inch low-
 profile (1.0 inch high) 1.06GB (formatted) disk drives. They all
 offer 9.0 millisecond average seek time for Reading, 9.5 millisecond
 seek time for Writing, with an average latency of only 5.55 ms. High
 capacity is achieved by utilizing a zone density recording
 technique using 9 recording zones at an areal density of 205 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. |   5.55 |
       +----------------------------------+--------+


 Error Correction
 ----------------
 The drive uses a three way interleaved 144-bit Reed-Solomon code to
 perform error correction and detection. For each 512-byte block,
 the on-the-fly error correction polynominal is capable of correcting:

 - one error burst of up to 22 bits in length

 - two error bursts each up to 11 bits in length


 ATTENTION!!!
 ============
 The Adapter for the CFP-1060 80pin SCA Model to 50pin SCSI exist with
 or without BRAZED terminators!


 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 5400 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.


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


 Buffer Management
 -----------------
 The 512K byte buffer is treated by the queuing code as two 240KB
 buffers (F0H sectors) to maximize coalescing. Look ahead reads are
 performed by the drive when there are no commands in the queue
 awaiting execution. Sequential read or write commands are coalesced
 into single commands to the background processor.
