 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.

Features

CONNER CFP-2107 PRODUCT MANUAL 501-071 6/94, PRE-RELEASE REV. A

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.
