 There are no jumpers to set on the model CFP2107E drive since all the
 necessary control signals are on the SCA connector. This drive is
 intended for applications where the drive is configured at the inter-
 face when drive is plugged into the interface connector.

 Disabling Spin-Up at Power On
 -----------------------------
 Spin up upon application of power to the drive can be diasabled by
 grounding the RMT_START line on the interface. 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.

 RMT_START |DSPN |Result
 ----------+-----+-------------------
 Ground    | 0   |Spin Disabled
 Ground    | 1   |Spin Disabled
 Open      | 0   |Spin Up on Power On
 Open      | 1   |Spin Disabled


 Delaying Spin Up at Power On
 ----------------------------
 Grounding the DLYD_START signal on the interface delays spin up on
 power-up by the value of the drive's SCSI ID multiplied by 4 seconds.
 Delaying spin up on application of power can also be enabled by
 setting the SDLY bit in MODE SELECT page 00H (Operating Parameters).

   +-----------------+

 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
 -----------------
 The drive is intended for direct backplane connection to the SCA
 connector rather than through cabling.


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


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


 Internal Termination
 --------------------
 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
 ------------------
 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
 ----------------------
 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
 ------------
 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
 -------
 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.

 Overview of the Drives
 ----------------------
 The CFP2107 series is a family of high performance 3.5-inch low-
 profile (1.0 inch high) 2.1GB (formatted) disk drives. They all offer
 8.5 millisecond average seek time for Reading, 9.0 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 144-bit Reed-Solomon code to
 perform error correction, plus a 6 bit CRC. 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.
