Jumper Setting
==============
Setting the SCSI Bus Address
----------------------------
There are four jumpers available for configuration of the SCSI ID:
E1, E2, E3 and E4.
The 68-pin unified connector includes a standard 2mm pitch auxiliary
header which includes pins to allow remote selection of SCSI IDs. A
receptacle connector Amp P/N 1-111623-7 or equivalent can be used to
connect a ribbon cable to this header.
The following table defines the relationship between the jumpers or
the pins on J5 and SCSI ID:
Setting the SCSI ID ------------------- +-------+----------+----------+----------+----------+ |SCSI ID|E1 / Pin 1|E2 / Pin 3|E3 / Pin 5|E4 / Pin 7| +-------+----------+----------+----------+----------+ | 0 |OUT/OPEN |OUT/OPEN |OUT/OPEN |OUT/OPEN | | 1 |IN /GROUND|OUT/OPEN |OUT/OPEN |OUT/OPEN | | 2 |OUT/OPEN |IN /GROUND|OUT/OPEN |OUT/OPEN | | 3 |IN /GROUND|IN /GROUND|OUT/OPEN |OUT/OPEN | | 4 |OUT/OPEN |OUT/OPEN |IN /GROUND|OUT/OPEN | | 5 |IN /GROUND|OUT/OPEN |IN /GROUND|OUT/OPEN | | 6 |OUT/OPEN |IN /GROUND|IN /GROUND|OUT/OPEN | | 7 |IN /GROUND|IN /GROUND|IN /GROUND|OUT/OPEN | | 8 |OUT/OPEN |OUT/OPEN |OUT/OPEN |IN /GROUND| | 9 |IN /GROUND|OUT/OPEN |OUT/OPEN |IN /GROUND| | 10 |OUT/OPEN |IN /GROUND|OUT/OPEN |IN /GROUND| | 11 |IN /GROUND|IN /GROUND|OUT/OPEN |IN /GROUND| | 12 |OUT/OPEN |OUT/OPEN |IN /GROUND|IN /GROUND| | 13 |IN /GROUND|OUT/OPEN |IN /GROUND|IN /GROUND| | 14 |OUT/OPEN |IN /GROUND|IN /GROUND|IN /GROUND| | 15 |IN /GROUND|IN /GROUND|IN /GROUND|IN /GROUND| +-------+----------+----------+----------+----------+ 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
---------------------------
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.
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.
J5 Auxiliary Connector Signal Definitions +---------------+-----------------+ |Pin Signal | Pin Signal | |Number Name | Number Name | +------+--------+-------+---------+ | 1 | -SEL0 | 2 | -XTFAULT| | 3 | -SEL1 | 4 | -VUNIQ | | 5 | -SEL2 | 6 | -SPSYNC | | 7 | -SEL3 | 8 | -XTAXTV | | 9 | -ENTERM| 10 | -GROUND | | 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. The pins for all of the drives which are to be synchronized
must be connected together. The drives must be of like model to
operate. 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%.
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.

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.
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 0.1 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.
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 samne SCSI Host Bus Adapter be-
ing used to control Wide SCSI devices. 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

External Terminator Power
-------------------------
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
--------------------
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
------------------
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
----------------------
The connector on the drive is a 68-pin. The mating connector is a
SCSI 3 Non-shielded P-cable connector.

CONNER CFP-2105 PRODUCT MANUAL 501-072 PRE-RELEASE REV. A, JULY 199
Overview of the Drives
----------------------
The CFP2105 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.
