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


 Setting the SCSI Bus Address
 ----------------------------
 There are four jumpers available for configuration of the SCSI ID:
 E1, E2, E3 and E4.


 Setting the SCSI ID
 -------------------
  +-------+----------+----------+----------+----------+
  |SCSI ID|    E1    |    E2    |   E3     |   E4     |

  +-------+----------+----------+----------+----------+
   Open means open circuit or high impedance. Ground means
   TTL logic low or logic ground.


 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. 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.
   +---------+------+---------------------+
   |   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 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 #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.


 Jumper E8 | Result
 ----------+----------------------------------------------------
   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.


 Setting the Bus Termination
 ---------------------------
 Remove the SCSI Terminators in all but the last drive in the chain.

CONNER   CFP-4207WD  PRODUCT MANUAL JUNE 1995 REV. A 501-084


 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

 - CSA 22.2#950, Safety of Electrically Energized Office Machines

 - IEC 380, Safety of Electrically Energized Office Machines

 - IEC 950, Safety of Information Technology Equipment Including
   Electrical Business Equipment

 - VDE 0805, VDE 0805 TIEL 100, VDE 0806

 - Complies with FCC Class B, Part 15, Subpart J
